Top SQL Server Google Searches For January 2006
These are the top SQL Searches on this site for the month of December. I have left out searches that have nothing to do with SQL Server or programming. Here are the results...
MS SQL zero fill
"Trouble Checker" "SQL Server"
sql server management studio
auto increment
SQL books
"dts step by step"
SSPI
sp_removedbreplication
sql server
SQl server books
triggers
sql login
sql security
I decided to blog about some of these searches, I see a lot of searches for books nowadays and also for login problems. I did create 2 posts about the login problems so that's covered for now. I will feature more books from now on

SQL Server Site Geo Map For January 2006
These are the countries where the bulk of the visitors for this blog are coming from. As you can see most of the visitors are from the US and Europe, Asia is in third place. When I look at the maps day by day I also see some visitors from Africa and the Middle East but you need more than one visitor per city in order for it to show up in the monthly map.

Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. SQL 2005
I am seeing a lot of searches on this blog or reaching this blog from MSN/Google with this search “SQL 2005 Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.” So this is what causes the problem: your SQL Server has been setup with windows authentication only. In order to make it mixed mode authentication right click on the server name in enterprise manager select properties and click on the security tab. Select SQL server and Windows Authentication mode(see picture…) and that will fix it The cool thing about SQL server 2005 is that you can script this out so that you can run the code on multiple servers instead of going to all the servers and clicking etc. Just click on script and code like the one below will be generatedUSE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2

NULL Trouble In SQL Server Land
I am seeing a lot of searches for SQL + Nulls from this site so I decided to blog about it
Before I start I would like to point out that all the code will behave this way if ANSI_NULLS is set to on ,not to off
CREATE TABLE testnulls (ID INT)
INSERT INTO testnulls VALUES (1)
INSERT INTO testnulls VALUES (2)
INSERT INTO testnulls VALUES (null)
CREATE TABLE testjoin (ID INT)
INSERT INTO testjoin VALUES (1)
INSERT INTO testjoin VALUES (3)
--We get back value 1 here
SELECT * FROM testjoin WHERE ID IN(SELECT ID FROM testnulls)
--Nothing is returned
SELECT * FROM testjoin WHERE ID NOT IN(SELECT ID FROM testnulls)
--Value 3 is returned
SELECT * FROM testjoin WHERE ID NOT IN(SELECT ID FROM testnulls WHERE ID IS NOT NULL)
--value 3 is returned
SELECT * FROM testjoin j
WHERE NOT EXISTS (SELECT n.ID
FROM testnulls n
WHERE n.ID = j.ID)
--value 3 is returned
SELECT j.* FROM testjoin j
LEFT OUTER JOIN testnulls n ON n.ID = j.ID
WHERE n.ID IS NULL
--a count of 3 is returned
SELECT COUNT(*) FROM testnulls
-- a count of 2 is returned, the count ignores NULL values
SELECT COUNT(id) FROM testnulls
--By using coalesce the count is also 3
SELECT COUNT(COALESCE(id,0)) FROM testnulls
--all 3 rows are returned
SELECT * FROM testnulls
-- 1 row is returned
SELECT * FROM testnulls
WHERE ID = 1
-- only 1 row is returned the row with the NULL value is ignored
SELECT * FROM testnulls
WHERE ID <> 1
-- Now both rows that are not 1 are returned
SELECT * FROM testnulls
WHERE ID <>1
OR ID IS NULL
-- Now both rows that are not 1 are returned also
SELECT * FROM testnulls
WHERE COALESCE(ID,0) <> 1
Some more NULL Fun
You can''t compare NULL with anything
Since both values are unknown even a comparison with another NULL is unknown
DECLARE @v INT
DECLARE @v2 INT
SELECT @v =NULL,@v2 = NULL
IF @v = @v2
SELECT 'yes'
ELSE
SELECT 'No'
Be carefull with forgetting to initialize parameters while building string
DECLARE @SQL VARCHAR(500)
DECLARE @Id INT
SELECT @SQL = 'SELECT * FROM testnulls
WHERE ID =' + CONVERT(VARCHAR,@Id)
SELECT @SQL

Format SQL Server Decimal Data
Yesterday someone posted a question in the SQL server
microsoft.public.sqlserver.programming news group about formatting decimal data. The person did not want trailing zeros or a decimal point if the amount was whole
The trick to do this is convert the decimal point to a space, rtrim it and then convert the space to a decimal. When you do that the trailing decimal point will vanish. The same applies for trailing zeros of course
output
.25000
.50000
1.00000
1.50000
2.00000
3.00000
desired output
0.25
0.5

Use XP_CMDSHELL To Get All File Names With Size In A Directory
To get all the files with their filesize in a directory use xp_cmdshell with a temporary table
After the temporary table is populated you will be able to sort the result set any way you like
CREATE TABLE #tempList (Files VARCHAR(500))
INSERT INTO #tempList
EXEC MASTER..XP_CMDSHELL 'dir c:\ '
--delete all directories
DELETE #tempList WHERE Files LIKE '%<dir>%'
--delete all informational messages
DELETE #tempList WHERE Files LIKE ' %'
--delete the null values
DELETE #tempList WHERE Files IS NULL
--get rid of dateinfo
UPDATE #tempList SET files =RIGHT(files,(LEN(files)-20))
--get rid of leading spaces
UPDATE #tempList SET files =LTRIM(files)
--split data into size and filename
SELECT LEFT(files,PATINDEX('% %',files)) AS Size,
RIGHT(files,LEN(files) -PATINDEX('% %',files)) AS FileName
FROM #tempList

Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. SQL 2000
I am seeing a ton of searches on this blog or reaching this blog from MSN/Google with this search “Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.” So this is what causes the problem: your SQL Server has been setup with windows authentication only. In order to make it mixed mode authentication right click on the server name in enterprise manager select properties and click on the security tab. Select SQL server and Windows (see picture…) and that will fix itI will monitor the searches and write more stuff about things that people are searching for.

Kill All Connections To Your SQL Server Database
Sometimes you need to restore a database and put it in single user mode but you can't because people are still using it. I will show you 2 ways to accomplish that
The first way is to loop through the sysprocesses table and kill all the processes one by one. The second way is to do an alter statement on the DB
--loop through the sysprocesses
DECLARE @sysDbName SYSNAME
SELECT @sysDbName = 'northwind'
SELECT IDENTITY(int, 1,1)AS ID,spid
INTO #LoopProcess
FROM master..sysprocesses
WHERE dbid = DB_ID(@sysDbName)
DECLARE @SPID SMALLINT
DECLARE @SQL VARCHAR(255)
DECLARE @MaxID INT, @LoopID INT
SELECT @LoopID =1,@MaxID = MAX(ID) FROM #LoopProcess
WHILE @LoopID <= @MaxID
BEGIN
SELECT @SPID = spid FROM #LoopProcess WHERE ID = @LoopID
SELECT @SQL = 'KILL ' + CONVERT(VARCHAR, @SPID)
EXEC( @SQL )
SELECT @LoopID = @LoopID +1
END
DROP TABLE #LoopProcess
--alter the DB by making it single user (all transaction will be rolled back)
ALTER DATABASE northwind SET SINGLE_USER WITH ROLLBACK IMMEDIATE
--do your restore here
-- Make the DB multi user again
ALTER DATABASE northwind SET MULTI_USER

Improve Your SQL Server Skills By Helping Others
Participating in forums and newsgroups is a great way to improve your SQL Server skills. You will see other people's problems and if you are just starting out then just relax and read the responses. The responses are most likely from a SQL Server MVP and these are top-quality. You will see many familiar authors in the MS public newsgroups such as Kalen Delaney, Itzik Ben-Gan, Adam Machanic, Louis Davidson and more. I have encountered SQL Server problems and remembered that I read about this on a SQL Server newsgroup and that a person posted a solution, from then on it's quick Google search and there you have it.
MS Public SQL Server Newsgroups
microsoft.public.sqlserver.newusers
microsoft.public.sqlserver.programming
microsoft.public.sqlserver.server
And a full list here
BTW these newsgroups can also be accessed by a newsreader as NTTP
Besides the newsgroups I also participate in the SQL Server Tek-Tip Forums for programming and administration What's great about Tek-Tips is the fact that people give stars to people who post a useful solution. So this will give you more incentives to post a good solution. You can also write searchable FAQ's

Like I said before you don't have to post solution but do at least spend some of your time reading the solutions to people's problems because sooner or later you might encounter them yourself.

sp_MSforeachtable
Find out fragmentation levels for all tables in your database by running the undocumented stored procedure sp_MSforeachtable
-- Create temp table
CREATE TABLE #fraglist (
ObjectName CHAR (255),
ObjectId INT,
IndexName CHAR (255),
IndexId INT,
Lvl INT,
CountPages INT,
CountRows INT,
MinRecSize INT,
MaxRecSize INT,
AvgRecSize INT,
ForRecCount INT,
Extents INT,
ExtentSwitches INT,
AvgFreeBytes INT,
AvgPageDensity INT,
ScanDensity DECIMAL,
BestCount INT,
ActualCount INT,
LogicalFrag DECIMAL,
ExtentFrag DECIMAL)
--Insert fragmentation level information
sp_MSforeachtable 'insert into #fraglist exec(''DBCC showcontig (''''?'''') with tableresults '') '
--Get all the info back
SELECT * FROM #fraglist
After you have run this you can determine which tables should be defragmented by looking at the AvgFreeBytes, ScanDensity, LogicalFrag and ExtenFrag columns

Find All Tables Without Triggers In SQL Server
Sometimes you want to change tables by adding columns, dropping or changing column types
You want to make sure that there aren't any tables that have triggers on them so that stuff doesn't start to break after you make these changes
I present two ways to accomplish that, the first way is by joining the INFORMATION_SCHEMA.TABLES view with the sysobjects system table.
The second way is to do a self join on the sysobjects system table. Both of these queries will return the same result
SELECT t.TABLE_NAME FROM INFORMATION_SCHEMA.TABLES t
LEFT JOIN(SELECT OBJECT_NAME(o.parent_obj) AS TableName
FROM sysobjects o
WHERE OBJECTPROPERTY(o.[id], 'IsTrigger') = 1
) tr ON t.TABLE_NAME= tr.TableName
WHERE tr.TableName IS NULL
AND TABLE_TYPE ='BASE TABLE'
ORDER BY t.TABLE_NAME
SELECT s1.name FROM sysobjects s1 LEFT JOIN sysobjects s2 ON
s1.id =s2.parent_obj
AND s2.xtype = 'TR'
WHERE s2.name IS NULL
AND s1.xtype = 'U'
ORDER BY s1.name

ISNUMERIC SQL Server Trouble
If you use the ISNUMERIC function to determine if a value is numeric you might be in for a surprise
Run the 3 lines of code below and you will see what I mean
DECLARE @S VARCHAR(50)
SET @S = CHAR(9) --- @S NOW CONTAINS THE TAB CHARACTER
SELECT ISNUMERIC(@S), ISNUMERIC(CHAR(9)),ISNUMERIC('1D2'),ISNUMERIC('D')
As you can see TAB is returned as numeric as well the value 1D2
A better way to test for this would be with LIKE and %[a-z]%
If you run the example below you will see that the select statement with the ISNUMERIC function or LIKE returns one row more than the statement with LIKE and ISNUMERIC combined
CREATE TABLE #foo (Value VARCHAR(20))
INSERT INTO #foo
SELECT '1' UNION ALL
SELECT '3' UNION ALL
SELECT 'B' UNION ALL
SELECT '2' UNION ALL
SELECT '33.331' UNION ALL
SELECT 'adad1' UNION ALL
SELECT '1d2' UNION ALL
SELECT '^' UNION ALL
SELECT '17777.999'
--returns ^
SELECT * FROM #foo
WHERE Value NOT LIKE '%[a-z]%'
--returns 1d2
SELECT * FROM #foo
WHERE ISNUMERIC(Value) = 1
--returns correct result
SELECT * FROM #foo
WHERE Value NOT LIKE '%[a-z]%'
AND ISNUMERIC(Value) = 1
Run the 3 lines of code below and you will see what I mean
DECLARE @S VARCHAR(50)
SET @S = CHAR(9) --- @S NOW CONTAINS THE TAB CHARACTER
SELECT ISNUMERIC(@S), ISNUMERIC(CHAR(9)),ISNUMERIC('1D2'),ISNUMERIC('D')

Compare Tables With Tablediff
In SQL Server 2005 there is a new utility to compare the data in two tables these can be in different tables and different servers.
The utility is Tablediff
The location is Program Files\Microsoft SQL Server\90\COM\tablediff.exe
From BOL:
The tablediff utility is used to compare the data in two tables for non-convergence, and is particularly useful for troubleshooting non-convergence in a replication topology. This utility can be used from the command prompt or in a batch file to perform the following tasks:
A row by row comparison between a source table in an instance of Microsoft SQL Server acting as a replication Publisher and the destination table at one or more instances of SQL Server acting as replication Subscribers.
Perform a fast comparison by only comparing row counts and schema.
Perform column-level comparisons.
Generate a Transact-SQL script to fix discrepancies at the destination server to bring the source and destination tables into convergence.
Log results to an output file or into a table in the destination database.
Look it up in Books On Line

Troubleshooting Performance Problems in SQL Server 2005
It is not uncommon to experience the occasional slow down of a SQL Server database. A poorly designed database or a system that is improperly configured for the workload are but several of many possible causes of this type of performance problem. Administrators need to proactively prevent or minimize problems and, when they occur, diagnose the cause and take corrective actions to fix the problem. This article provides step-by-step guidelines for diagnosing and troubleshooting common performance problems by using publicly available tools such as SQL Server Profiler, System Monitor, and the new Dynamic Management Views in SQL Server 2005
There is also a word document versionf for download
If you are a SQL Server 2005 developer/administrator then this is a must read
You will be introduced to new views such as sys.dm_exec_sql_text, sys.dm_exec_cached_plan, Sys.dm_db_index_operational_stats and sys.dm_db_index_usage_stats
Below is a short list of what is covered in the article
Resource Bottlenecks
Tools for resolving resource bottlenecks
CPU Bottlenecks
Excessive compilation and recompilation

SQL Server Site Geo Map For December
These are the countries where the bulk of the visitors for this blog are coming from. As you can see most of the visitors are from the US and Europe, Asia is in third place. When I look at the maps day by day I also see some visitors from Africa and the Middle East but you need more than one visitor per city in order for it to show up in the monthly map. I only started Google Analytics at the end of November To see the November geo map click here

Format SQL Server Money Data Type
Sometimes you want to have your money fields properly formatted with commas like this: 13,243,543.57
You can use the CONVERT function and give a value between 0 and 2 to the style and the format will be displayed based on that
Below is an example
DECLARE @v MONEY
SELECT @v = 1322323.6666
SELECT CONVERT(VARCHAR,@v,0) --1322323.67 Rounded but not formatted
SELECT CONVERT(VARCHAR,@v,1) --1,322,323.67 Formatted with commas
SELECT CONVERT(VARCHAR,@v,2) --1322323.6666 No formatting
If you have a decimal field it doesn't work with the convert function. The work around is to cast it to money
DECLARE @v2 DECIMAL (36,10)
SELECT @v2 = 13243543.56565656
SELECT CONVERT(VARCHAR,CONVERT(MONEY,@v2),1) --13,243,543.57 Formatted with commas
You can use the CONVERT function and give a value between 0 and 2 to the style and the format will be displayed based on that

DECLARE @v MONEY

How To Resolve A Deadlock
I stumbled upon this SQL Server technical bulletin and it gives one example of how to resolve a deadlock. Typical methods you can use to resolve deadlocks include:
Adding and dropping indexes.
Adding index hints.
Modifying the application to access resources in a similar pattern.
Removing activity from the transaction like triggers. By default, triggers are transactional.
Keeping transactions as short as possible.
I won't go into details here since you can read it all at the following link (SQL Server technical bulletin - How to resolve a deadlock)
Also check out the following deadlock links
Deadlocking
Handling Deadlocks
Minimizing Deadlocks
Troubleshooting Deadlocks
Lock Compatibility
And of course if you really want to know everything about locking I recommend the following book (in PDF format): Hands-On SQL Server 2000 : Troubleshooting Locking and Blocking by Kalen Delaney (Inside SQL Server 2000)

SQL Query Optimizations
Below are a couple of small SQL query optimization tips
I have include the execution plan pictures for some of the queries so that you can see the difference
Don’t use * but list the columns
SELECT pub_name,city FROM dbo.publishers instead of SELECT * FROM dbo.publishers
If you would have a covering index on the columns pub_name and city then the table would not be accessed at all and all the data would be returned from the index. This would also reduce the logical reads. You can use STATISTICS IO to find out how many logical reads you would have
SELECT pub_name,city FROM dbo.publishers
Table 'Products'. Scan count 1, logical reads 1, physical reads 0, read-ahead reads 0.
SELECT * FROM dbo.publishers
Table 'Products'. Scan count 1, logical reads 7, physical reads 0, read-ahead reads 0.
Don’t use arithmetic operators on a column in the where clause
You will get an index scan instead of a seek
SELECT * FROM Orders WHERE OrderID*3 = 33000
SELECT * FROM Orders WHERE OrderID = 33000/3
Don’t use functions on a column in the where clause
You will get an index scan instead of a seek
SELECT * FROM Orders WHERE LEFT(CustomerID,1) ='V'
SELECT * FROM Orders WHERE CustomerID LIKE 'V%'
Don’t convert a datetime column in the where clause
SELECT * FROM Orders WHERE OrderDate = '1996-07-04'
SELECT * FROM Orders WHERE CONVERT(CHAR(10),OrderDate,120) = '1996-07-04'
As you can see the query is many time faster if you don't convert

Test SQL Server Login Permissions With SETUSER
Sometimes you get a request to create a login and you want to test the permissions before letting the user know that he can use the login. you just don't feel like login in and trying to run some SQL statements for every user.
With the SETUSER statement you can eliminate that. Here is some code that explains how to use it
--Create the user
EXEC sp_addlogin 'Albert', 'food', 'pubs'
EXEC sp_adduser 'Albert'
CREATE TABLE dbo.test(id INT identity,datefield DATETIME)
INSERT INTO test
SELECT GETDATE()
SELECT * FROM test -- as dbo
-- let's run the select as Albert
SETUSER 'Albert'
SELECT * FROM test -- as albert
Now you should get this error
Server: Msg 229, Level 14, State 5, Line 1
SELECT permission denied on object 'test', database 'pubs', owner 'dbo'.
execute just the SETUSER statement and you can drop Albert since the user will be reset to the original user
SETUSER
EXEC sp_dropuser 'Albert'
EXEC sp_droplogin 'Albert'
or close the query window and in another window execute the code below to drop Albert
You have to do this in another window since as Albert you don't have permissions to do this
EXEC sp_dropuser 'Albert'
EXEC sp_droplogin 'Albert'
With the SETUSER statement you can eliminate that. Here is some code that explains how to use it
--Create the user
EXEC sp_addlogin 'Albert', 'food', 'pubs'
EXEC sp_adduser 'Albert'
CREATE TABLE dbo.test(id INT identity,datefield DATETIME)
INSERT INTO test
SELECT GETDATE()
SELECT * FROM test -- as dbo
-- let's run the select as Albert
SETUSER 'Albert'
SELECT * FROM test -- as albert
Now you should get this error
Server: Msg 229, Level 14, State 5, Line 1
SELECT permission denied on object 'test', database 'pubs', owner 'dbo'.
execute just the SETUSER statement and you can drop Albert since the user will be reset to the original user
SETUSER
EXEC sp_dropuser 'Albert'
EXEC sp_droplogin 'Albert'
or close the query window and in another window execute the code below to drop Albert
You have to do this in another window since as Albert you don't have permissions to do this
EXEC sp_dropuser 'Albert'
EXEC sp_droplogin 'Albert'

Fun With SQL Server Update Triggers
Below is some code that will show how to test for updated field values in an update trigger. As you can see the IF UPDATE (field) is true even when the values don’t change. Another thing to keep in mind is that if a value changes from NULL to something else and vice-versa, and you are comparing deleted and inserted tables without using COALESCE or ISNULL it won’t return those rows. Run the code below to see what I mean
CREATE TABLE TestTrigger (TestID INT identity,
name VARCHAR(20),
value DECIMAL(12,2) ,
CONSTRAINT chkPositiveValue CHECK (value > 0.00) )
INSERT INTO TestTrigger
SELECT 'SQL',500.23
CREATE TRIGGER trTest
ON TestTrigger
FOR UPDATE
AS
IF @@ROWCOUNT =0
RETURN
IF UPDATE(value)
BEGIN
SELECT '1', * FROM deleted d JOIN inserted i ON d.testid =i.testid
SELECT '2',* FROM deleted d JOIN inserted i ON d.testid =i.testid
AND i.value <> d.value
SELECT '3',* FROM deleted d JOIN inserted i ON d.testid =i.testid
AND COALESCE(i.value,-1) <> COALESCE(d.value,-1)
END
GO
--Let's update the value to 100
UPDATE TestTrigger SET value = 100 WHERE testid =1
--we get back all 3 rows
--Let's run the same statement
UPDATE TestTrigger SET value = 100 WHERE testid =1
--we get back the first row
--Let's really update
UPDATE TestTrigger SET value = 200 WHERE testid =1
--we get back all 3 rows
--Let's update with NULL
UPDATE TestTrigger SET value =NULL WHERE testid =1
--we get back rows 1 and 3, row 2 is not returned because it can't compare it
--Let's update with NULL again
UPDATE TestTrigger SET value =NULL WHERE testid =1
--we get back row 1
--Let's update with 300
UPDATE TestTrigger SET value =300 WHERE testid =1
--we get back rows 1 and 3, row 2 doesn't return because it can't compare NULL to 300
--Let's update with 500

Keep Your Statistics Up To Date
I had a scheduled job that runs every hour and took about a minute to complete. Somehow for no good reason this job suddenly takes hours and hours to finish. There was nothing done to the server, no service packs or patches. I checked fragmentation with DBCC SHOWCONTIG and it looked fine. I checked for blocking by running sp_who2 and there was no blocking going on. Now I was puzzled, what could have caused this? The table is not huge, about 50000 rows. Then I decided to update the statistics by running UPDATE STATISTICS and the problem went away immediately. The strange part is that there was such a huge difference in excution time, if it was double or triple I would understand but this was hunderds times slower. I don't have auto update statistics enabled because I have huge tables and can not have SQL server running sp_updatestats in the middle of the day. I have added this one table to the statistics job that I currently have and will monitor if the stats are up to date

SQL Server 2000 Undocumented Procedures For Files, Drives and Directories
Below are some undocumented SQL Server 2000 procedures for information about files, drives and directories.
You should not depend on this because they might me deprecated in the future, but if you want to find out fast if a file exists, what the size is and other things I think that they are good to use since it saves you some scripting or using terminal services
returns the network name of the server
master..xp_getnetname
Returns 1 if a file exists, 1 if the file is a directory and 1 if a parent directory exists
master..xp_fileexist 'C:\Program Files\Microsoft SQL Server\MSSQL\readme.txt'
Lists all the subdirecories of a given path including the level of the path
master..xp_dirtree 'C:\Program Files\Microsoft SQL Server\MSSQL\'
Lists a directory's immediate sub directory (1 level down)
master..xp_subdirs 'C:\Program Files\Microsoft SQL Server\MSSQL\'
List the file detals for a file, the following fields are returned
Alternate Name,Size,Creation Date, Creation, Time Last Written, Date Last Written, Time Last Accessed,

Use OBJECTPROPERTY To Find Out Table Properties
How many times did you open up a table in design view to find out if a table has
a delete trigger
a clustered index
an identity column
a primary key
a timestamp
a unique constraint
etc etc?
There is an easier way to find out all this info by using the OBJECTPROPERTY function
You will have to get the object id from the table to pass it into the OBJECTPROPERTY function.
To get the object id you can use the OBJECT_ID function.
Run the code below in the Northwind database to see how it works
USE Northwind
DECLARE @objectID INT
SELECT @objectID =OBJECT_ID('customers')
select OBJECTPROPERTY(@objectID,'TableDeleteTrigger') AS 'Table Has A Delete Trigger',
OBJECTPROPERTY(@objectID,'TableHasClustIndex') AS 'Table Has A Clustered Index',
OBJECTPROPERTY(@objectID,'TableHasIdentity') AS 'Table Has An Identity Column',
OBJECTPROPERTY(@objectID,'TableHasPrimaryKey') AS 'Table Has A Primary Key',
OBJECTPROPERTY(@objectID,'TableHasTimestamp') AS 'Table Has A Timestamp',
OBJECTPROPERTY(@objectID,'TableHasUniqueCnst') AS 'Table Has A Unique Constraint',
OBJECTPROPERTY(@objectID,'IsAnsiNullsOn') AS 'ANSI NULLS Is Set To ON'
Lookup OBJECTPROPERTY in Books On Line to find out about additional properties

SQL Server 2005 Launch In Philadelphia
I have attended the SQL Server 2005 Launch In Philadelphia. It was very informative I learned some stuff I didn't know and saw some usefull implementations of the new features. There were about 30-40 vendors present. The one vendor that I hoped would be there was not. This company is red-gate and they are the makers of a product called SQL Compare I have used this product for about 2 years now and was hoping to speak to someone and letting them know how much I liked their product. The Architecting Scalable Flexible and Secure Database Systems track was interesting as well as all the others. What kind of goodies did you receive here? Of course everyone received SQL 2005 Standard and Visual studio 2005 Standard Editions. Also included was Windows 2003 Server R2 RC1, Biztalk server 2006 CTP, A free exam voucher, free Biztalk 2006 Developer Edition download (after registering for the beta download) and a shirt of course (ironically Philadelphia is not mentioned on the shirt).
Perhaps the best give away was the Launch 2005 Resource DVD, it is packed with all kinds of stuff. For SQL Server these are

SQL Server 2005 Book Rant
I have 2 store credits one for Borders and the other one for Barnes and Noble. So I decided to buy the Pro SQL server 2005 and SQL Server 2005 Administrators Companion this Saturday. I first went to Barnes and Noble and no books. So that already damped my mood. Next I decided to go to Borders and the same thing no books either. This really made me furious, how long does it take for a store to get the books? I wanted instant gratification and I can’t have any. So I went home and ordered them on Amazon I just hope I will get them by Wednesday.

Cannot add, update, or delete a job that originated from an MSX Server
Well this is one of those very friendly error messages that when you look at it you know immediately what is going on. Of course I am being sarcastic here. This happened to a client who was migrating their servers and backed up all the SQL server Databases and restored them on the new machine they bought. What happened is this, they named the new machine differently than the old machine. When you look at the jobs you can see them (and that’s about it). You can not delete, update or run these jobs. Unfortunately renaming the server was not an option for the client. I looked in the sysjobs table in the msdb database and found out that the name stored was the old servers name
SELECT originating_server FROM msdb..sysjobs
I then updated the originating_server fields in the table with the new server name value and everything was fine after that. As far as I know this doesn't effect SQL server 7 since it stores (local) in the originating_server column
SELECT originating_server FROM msdb..sysjobs

Pad Numbers By Using CASE, LEFT And CONVERT
Let's say you have a table with integer values below 100000 and you want them in the same format with leading zeros. For example 500 has to be 000500 and 1 has to be 000001
How do you do this in SQL server?
Below are two ways to accomplish this.
CREATE TABLE #ValueTable (value INT)
INSERT INTO #ValueTable
SELECT 1
UNION ALL
SELECT 500
UNION ALL
SELECT 4000
UNION ALL
SELECT 50000
--Use CASE, LEN and CONVERT to pad the values
SELECT value,CASE LEN(value)
WHEN 1 THEN '00000' + CONVERT(VARCHAR,value)
WHEN 2 THEN '0000' + CONVERT(VARCHAR,value)
WHEN 3 THEN '000' + CONVERT(VARCHAR,value)
WHEN 4 THEN '00' + CONVERT(VARCHAR,value)
WHEN 5 THEN '0' + CONVERT(VARCHAR,value)
ELSE CONVERT(VARCHAR,value)
END AS Formattedvalue
FROM #ValueTable
--Use LEFT, LEN and CONVERT to pad the values
SELECT value,LEFT('000000',(6 -LEN(value )))
+ CONVERT(VARCHAR,value) AS Formattedvalue
FROM #ValueTable
I have received a comment from Rob Farley who was so kind to point out to me that I should have used RIGHT instead of left
Here is the code he supplied
--Use RIGHT to pad the value
SELECT value, RIGHT('000000' + CONVERT(VARCHAR,value),6) AS FormattedValue
FROM #ValueTable
How do you do this in SQL server?
Below are two ways to accomplish this.
CREATE TABLE #ValueTable (value INT)
INSERT INTO #ValueTable
SELECT 1
UNION ALL
SELECT 500
UNION ALL
SELECT 4000
UNION ALL
SELECT 50000
--Use CASE, LEN and CONVERT to pad the values
SELECT value,CASE LEN(value)
WHEN 1 THEN '00000' + CONVERT(VARCHAR,value)
WHEN 2 THEN '0000' + CONVERT(VARCHAR,value)
WHEN 3 THEN '000' + CONVERT(VARCHAR,value)
WHEN 4 THEN '00' + CONVERT(VARCHAR,value)
WHEN 5 THEN '0' + CONVERT(VARCHAR,value)
ELSE CONVERT(VARCHAR,value)
END AS Formattedvalue
FROM #ValueTable

SELECT value,LEFT('000000',(6 -LEN(value )))
+ CONVERT(VARCHAR,value) AS Formattedvalue

Formatting Data By Using CHARINDEX And SUBSTRING
Let's say you have names stored in the format [Klein, Barbara] but would like it to be [Barbara Klein]
How do you accomplish that in SQL?
SQL provides 2 useful functions (CHARINDEX And SUBSTRING)
Run the code below to see how they work
CREATE TABLE Names (ID INT identity not null,NameField VARCHAR(50), ProperNameField VARCHAR(50))
INSERT INTO Names
SELECT 'Klein, Barbara',NULL
UNION ALL
SELECT 'Smith, John',NULL
UNION ALL
SELECT 'Jackson, Michael',NULL
UNION ALL
SELECT 'Gates, Bill',NULL
UPDATE Names
SET ProperNameField =SUBSTRING(NameField,CHARINDEX(',',NameField) + 2,
LEN(NameField) - CHARINDEX(',',NameField))
+ ' ' + LEFT(NameField,CHARINDEX(',',NameField)-1)
SELECT * FROM Names

Finding ASCII, Numbers and Alphabet Characters In SQL Server Tables
SQL Server has limited support for regular expressions,
You can run the code below to see what some of the results are by searching for data while using regular expressions
CREATE TABLE AsciiTest (id INT identity, TextField VARCHAR(50))
INSERT INTO AsciiTest
SELECT '%&&&123%#$#$'
UNION ALL
SELECT 'safdsfsdrfsdfse'
UNION ALL
SELECT '12121212'
UNION ALL
SELECT '1212asasas'
UNION ALL
SELECT '%&&&%#$#$'
UNION ALL
SELECT '4564gg565656'
UNION ALL
SELECT '12'
--No Alphabet Characters
SELECT * FROM AsciiTest
WHERE TextField NOT LIKE '%[a-Z]%'
--Starting with a number
SELECT * FROM AsciiTest
WHERE TextField LIKE '[0-9]%'
--Ending with a number
SELECT * FROM AsciiTest
WHERE TextField LIKE '%[0-9]'
--Numbers and characters
SELECT * FROM AsciiTest
WHERE TextField LIKE '%[0-Z]%'
--Only non alphabet/numbers characters
SELECT * FROM AsciiTest
WHERE TextField NOT LIKE '%[0-Z]%'
--some non alphabet/number characters
SELECT * FROM AsciiTest
WHERE TextField LIKE '%[^0-Z]%'
-- ASCII Code 38 (&)
SELECT * FROM AsciiTest
WHERE TextField LIKE '%' + char(38) + '%'
You can run the code below to see what some of the results are by searching for data while using regular expressions
CREATE TABLE AsciiTest (id INT identity, TextField VARCHAR(50))
INSERT INTO AsciiTest
SELECT '%&&&123%#$#$'
UNION ALL
SELECT 'safdsfsdrfsdfse'
UNION ALL
SELECT '12121212'
