Three Way To List All Databases On Your Server

Sometimes you want to print out a document with all the databases that exists on one server so that you can compare this against another server for example
Listed below are three ways to accomplish this by using a system table, a system view and an undocumented stored procedure

First Way
Use the INFORMATION_SCHEMA.SCHEMATA system view

SELECT CATALOG_NAME FROM INFORMATION_SCHEMA.SCHEMATA
WHERE CATALOG_NAME NOT IN('master','msdb','tempdb','model')
ORDER BY CATALOG_NAME

Second Way
Use the sysdatabases system table in the master database

SELECT name FROM master..sysdatabases
WHERE name NOT IN('master','msdb','tempdb','model')
ORDER BY Name

Third way
Use the undocumented sp_MSForEachDB procedure

CREATE TABLE #AllDB (Name VARCHAR(100))
INSERT INTO #AllDB
EXEC sp_MSForEachDB 'IF ''?'' NOT IN (''master'', ''model'', ''msdb'', ''tempdb'')
SELECT ''?'' '
SELECT * FROM #AllDB

Convert Float Stored As Varchar To Numeric

An interesting problem came up today in the microsoft SQL Server DTS newsgroup
A person tried to convert a varchar value to numeric and got the following message "Error converting data type varchar to numeric."
The problem is that the value stored as varchar is a float and then SQL Server is not able to convert this to a numeric datatype
So first you have to convert to float and then to numeric


DECLARE @Value VARCHAR(50)
SELECT @Value = '5.9499999999999997E-2'

--Error converting data type varchar to numeric.
SELECT CONVERT(NUMERIC(21,20),@Value)

--This works after converting to float first
SELECT CONVERT(NUMERIC(21,20),CONVERT(FLOAT,@Value))


--No problems here since the value in the varchar field can be converted to numeric
DECLARE @Value2 VARCHAR(50)
SELECT @Value2 = '5.9499999999999997'

SQL Server And Business Intelligence Podcast

Channel 9 on MSDN has added another SQL server podcast yesterday, this one is about SQL Server And Business Intelligence

XML In SQL Server 2005 Podcast

XML in SQL Server 2005
Channel9 at MSDN.com has a great SQL Server 2005 and XML podcast
From the page: "How much code have you seen that is devoted to simply shredding XML and storing it in a database? What if you didn't need to do that anymore? What if you could store XML in all of it's unstructured hierarchical goodness and just leave it at that? Well my friend, you are in luck because on this episode Shankar Pal of the SQL Server team is going to tell you all about the details of the great new XML support in SQL Server 2005."

Sort A SQL Server Table With CASE Or CHARINDEX

Let's say you have a table with states in your database, you only have 3 values NY, ME and SC.
You want to order the result like this: first NY followed by SC and ME last.
You can do that in two different ways
One: use a case statement in your order by
Two: use Charindex in your order by
Let's see how that works

CREATE TABLE #TEST (
STATE CHAR(2))

INSERT INTO #TEST
SELECT 'ME' UNION ALL
SELECT 'ME' UNION ALL
SELECT 'ME' UNION ALL
SELECT 'SC' UNION ALL
SELECT 'NY' UNION ALL
SELECT 'SC' UNION ALL
SELECT 'NY' UNION ALL
SELECT 'SC'

-- order by using CASE

SELECT *
FROM #TEST
ORDER BY CASE STATE
WHEN 'NY' THEN 1
WHEN 'SC' THEN 2
ELSE 3
END

--Order by using CHARINDEX
SELECT *
FROM #TEST
ORDER BY CHARINDEX(STATE,'NY-SC-ME')

--or without NY since CHARINDEX will return 0 for NY and it will be first
SELECT *
FROM #TEST
ORDER BY CHARINDEX(STATE,'SC-ME')


--the problem is of course if you have more values and you only want to have NY and SC showing up first and second
--let's insert 2 more rows
INSERT INTO #TEST
SELECT 'IL'
UNION ALL
SELECT 'CA'

-- Now the CHARINDEX Order doesn't work
-- the trick is to make it Descending and switch the states around
SELECT *
FROM #TEST
ORDER BY CHARINDEX(STATE,'SC-NY') DESC

or this way

--Order by using CHARINDEX DESC
SELECT *
FROM #TEST
ORDER BY CHARINDEX(STATE,'ME-SC-NY') DESC

User Definded Functions And GETDATE() (nondeterministic built-in functions )

I have read on Louis Davidson's blog a post about UDF and being able to use GETDATE() in a UDF in SQL server 2005. I wasn't aware of that so I would like to bring it to your attention
In SQL server 2005 you are able to use the following nondeterministic built-in functions in Transact-SQL user-defined functions:
CURRENT_TIMESTAMP
GET_TRANSMISSION_STATUS
GETDATE
GETUTCDATE
@@PACK_SENT
@@PACK_RECEIVED
@@MAX_CONNECTIONS
@@PACKET_ERRORS
@@CONNECTIONS
@@TIMETICKS
@@CPU_BUSY
@@TOTAL_ERRORS
@@DBTS
@@TOTAL_READ
@@IDLE
@@TOTAL_WRITE
@@IO_BUSY

So let's get started and test it out, I will create 2 UDF's one that uses GETDATE() and one that uses DATEADD() and GETDATE()

CREATE FUNCTION fnNonDeterministic ()
RETURNS DATETIME
AS
BEGIN
RETURN GETDATE()
END
GO

CREATE FUNCTION fnNonDeterministicAdd (@Days int)
RETURNS DATETIME
AS
BEGIN
RETURN DATEADD(d,@Days,GETDATE())
END
GO

--Let's see what the ouput is
SELECT dbo.fnNonDeterministic() AS DateReturned,
dbo.fnNonDeterministicAdd(2) AS DateAddReturned

Use CHARINDEX, LEN and SUBSTRING To Find Data Between Characters

Let's say you get data in the following format aaaa/bbbb/cccc/dddd/eeee
What you need from this file is just the data between the first and the last forward slash (in thid case bbbb)
If there is no slash in the file then grab all the data, if there is only 1 slash then grab everything after that slash
This was actually one of the questions that I have answered on tek-tips so yes data like this does exist.
How do you attack such a problem?
First you have to find the first slash, you do that by using CHARINDEX, CHARINDEX will return the position where the first slash is located, then you use CHARINDEX again with SUBSTRING to find the Second slash, finally you use SUBSTRING with the LEFT function and the difference between the 2 CHARINDEX calls as the length
I used a replace function at the beginning to check if there is more than 1 slash or not and then a case statement later on depending on the outcome of that replace function
Let’s see how I did it

--Create some test data
CREATE TABLE #test (ValueField VARCHAR(50))
INSERT INTO #test
SELECT ' /aaaa' UNION ALL
SELECT ' /yyyy/bbbb ' UNION ALL
SELECT 'zzzzz/c/defgh ' UNION ALL
SELECT 'VVVVV'

--This is our delimiter
DECLARE @Delimiter CHAR(1)
SET @Delimiter = '/'

--Show the whole field and the extracted value
SELECT ValueField AS Originalvalue,
CASE WHEN LEN(ValueField) -LEN(REPLACE(ValueField,@Delimiter,'')) > 1
THEN LEFT(SUBSTRING(ValueField,CHARINDEX(@Delimiter,ValueField)+1 ,LEN(ValueField)),CHARINDEX(@Delimiter,SUBSTRING(ValueField,CHARINDEX(@Delimiter,ValueField)+1 ,LEN(ValueField)))-1)
ELSE SUBSTRING(ValueField,CHARINDEX(@Delimiter,ValueField)+1 ,LEN(ValueField))END AS ExtractedValue
FROM #test

How To Check For A Certain Time With SQL

Sometimes you have jobs and you don't know how long they will run
Let's just assume here that the job has 2 steps
You run step 1 and it takes x hours, you only want to run step 2 if it's before 5:45 AM because some other job will start at 6:00 AM and you don't want those 2 jobs hitting the same table at the same time (a real world scenario might be different of course, this is just a simplified version)

I hardcoded 05:45:00.000 here, you can of course store this in a parameter or even in a table so that you only have to change it in one place


--Get today's date
DECLARE @CurrentDateTime DATETIME
SET @CurrentDateTime = GETDATE()

-- create a 2nd parameter and append the time that you need to check for
DECLARE @TimeToChek DATETIME
SELECT @TimeToChek = CONVERT(VARCHAR,@CurrentDateTime,101) + ' 05:45:00.000'



IF (@CurrentDateTime <= @TimeToChek)
-- It is before 5:45 AM
BEGIN
SELECT 'before 5:45am' OutputStatus,
@CurrentDateTime AS CurrentTime,
@TimeToChek AS TimeToCheck
END
ELSE
-- it is before 5:45 AM
BEGIN
SELECT 'Not before 5:45am' OutputStatus,
@CurrentDateTime AS CurrentTime,
@TimeToChek AS TimeToCheck
END

Check If Temporary Table Exists

How do you check if a temp table exists?
You can use IF OBJECT_ID('tempdb..#temp') IS NOT NULL
Let's see how it works

--Create table
USE Norhtwind
GO

CREATE TABLE #temp(id INT)

--Check if it exists
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END

--Another way to check with an undocumented optional second parameter
IF OBJECT_ID('tempdb..#temp','u') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END



--Don't do this because this checks the local DB and will return does not exist
IF OBJECT_ID('tempdb..#temp','local') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END


--unless you do something like this
USE tempdb
GO

--Now it exists again
IF OBJECT_ID('tempdb..#temp','local') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END

--let's go back to Norhtwind again
USE Norhtwind
GO


--Check if it exists
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END

now open a new window from Query Analyzer (CTRL + N) and run this code again
--Check if it exists
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
BEGIN
PRINT '#temp exists!'
END
ELSE
BEGIN
PRINT '#temp does not exist!'
END


It doesn't exist and that is correct since it's a local temp table not a global temp table


Well let's test that statement
--create a global temp table
CREATE TABLE ##temp(id INT) --Notice the 2 pound signs, that's how you create a global variable

--Check if it exists
IF OBJECT_ID('tempdb..##temp') IS NOT NULL
BEGIN
PRINT '##temp exists!'
END
ELSE
BEGIN
PRINT '##temp does not exist!'
END

It exists, right?
Now run the same code in a new Query Analyzer window (CTRL + N)

--Check if it exists
IF OBJECT_ID('tempdb..##temp') IS NOT NULL
BEGIN
PRINT '##temp exists!'
END
ELSE
BEGIN
PRINT '##temp does not exist!'
END

And yes this time it does exist since it's a global table

SQL:Format Data From Numberformat To Timeformat

Sometimes you have data that's in a number format and you need to show it in a time format. Instead of 2.25 you need to show 02:15
In that case you can use a combination of CONVERT and DATEADD
Run the examples below to see how it works

DECLARE @a DECIMAL(6,2)
SELECT @a = 3.00
SELECT @a AS OldValue,
CONVERT(CHAR(5), DATEADD(ss, @a * 3600, 0), 108) AS TimeFormatted

SELECT @a = 3.15
SELECT @a AS OldValue,
CONVERT(CHAR(5), DATEADD(ss, @a * 3600, 0), 108) AS TimeFormatted

SELECT @a = 3.25
SELECT @a AS OldValue,
CONVERT(CHAR(5), DATEADD(ss, @a * 3600, 0), 108) AS TimeFormatted


SELECT @a = 3.75
SELECT @a AS OldValue,
CONVERT(CHAR(5), DATEADD(ss, @a * 3600, 0), 108) AS TimeFormatted

Varchar To Varbinary And Vice Versa

I have received an email from someone in Taiwan who looked at the contact me blog entry and wanted to know how I ‘encrypted’ my email address like that. Well there really is not much to it, you just convert the email string to varbinary. Then you convert it back to varchar to get the string back
For example if my email address is abc@qwerty.NotCom then you would do
SELECT CONVERT(VARBINARY(17),'abc@qwerty.NotCom')

This would return 0x616263407177657274792E4E6F74436F6D

Then you do
SELECT CONVERT(VARCHAR(17),0x616263407177657274792E4E6F74436F6D)
to see the string again
Of course you will have to increase the size of the varchar and the varbinary field if it exceeds 17 bytes

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 generated

USE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2
GO

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
