Enough said.

How To Get The Database Name For The Current User Process

This question pops up frequent enough so here are 4 ways to return the database name for the current user process

First up is the fastest method. this will run on SQL Server 200 and 2005

SELECT DB_NAME()


Next up is getting the name by joining the sys.dm_exec_requests dmv and sys.sysdatabases. this runs on SQL Server 2005 only

SELECT s.name
FROM sys.dm_exec_requests d
JOIN sys.sysdatabases s on d.database_id = s.dbid
WHERE session_id = @@SPID

Here is something similar, this also runs only on SQL Server 2005

SELECT name
FROM sys.sysdatabases
WHERE dbid = DB_ID()


And we end with something that runs on both SQL Server 2005 and 2000
SELECT name
FROM master..sysdatabases
WHERE dbid = DB_ID()


But like I said before you should always use DB_NAME()

SQL Server 2005 Performance Dashboard Reports Available For Download

The SQL Server 2005 Performance Dashboard Reports are Reporting Services report files designed to be used with the Custom Reports feature introduced in the SP2 release of SQL Server Management Studio. The reports allow a database administrator to quickly identify whether there is a current bottleneck on their system, and if a bottleneck is present, capture additional diagnostic data that may be necessary to resolve the problem. For example, if the system is experiencing waits for disk IO the dashboard allows the user to quickly see which sessions are performing the most IO, what query is running on each session and the query plan for each statement.

Common performance problems that the dashboard reports may help to resolve include:
- CPU bottlenecks (and what queries are consuming the most CPU)
- IO bottlenecks (and what queries are performing the most IO).
- Index recommendations generated by the query optimizer (missing indexes)
- Blocking
- Latch contention

The information captured in the reports is retrieved from SQL Server's dynamic management views. There is no additional tracing or data capture required, which means the information is always available and this is a very inexpensive means of monitoring your server.

Reporting Services is not required to be installed to use the Performance Dashboard Reports.

Keep in mind that the SQL Server instance being monitored must be running SP2 or later.

R.I.P Visual FoxPro

Where is the wake ;-) Finally this thing is about to die, no more having to deal with 40 tables because each FoxPro table has a 2GB limit. And don’t get me started with exclusively locked tables either. I think that I will listen to die, die my darling by Metallica while I finish this post. Here are some of the lyrics

Die, die, die my darling
Dont utter a single word
Die, die, die my darling
Just shut your Foxy eyes (I replaced pretty with Foxy)

So for all you FoxPro lovers, there is a great new site (so there is hope for you ;-)) VFP-Conversion

Think Outside the Fox-Den!

map of the world, based on the frequency of its locations mentioned in books.


Here is something interesting and it has to do with data. Inside Google Book Search has some neat maps of the world based on the frequency of its locations mentioned in books. From the site:
We've all seen views of the Earth from space, where the numerous pinpoints of light on the ground combine to yield a speckled map of the world. I wanted to show the Earth viewed from books, where individual mentions of locations in books combine to yield another interpretation of the globe. The intensity of each pixel is proportional to the number of times the location at a given set of coordinates is mentioned across all of the books in Google Books Search.


Here is the link: http://booksearch.blogspot.com/2007/03/earth-viewed-from-books.html

how to save a whole heap of money on SQL Server 2000 licenses

I Just read this on the daily WTF (which got renamed to Worse Than Failure the other day)
An insurance company decides to install the trial version of SQL server 2000 on their production box because they don't want to pay the license. After 6 months they backup all the data, wipe out the hard drive (reimage) and install the trial version again, restore all the databases and are good to go for another 6 months...ROFL
Why not just use developer edition? You are violating the license anyway, it will at least save you the hassle of reinstalling every 6 months...

How To Make A FileGroup Read Only in SQL Server 2005

How to make a filegroup read only in SQL Server 2005? This question popped up today on tek-tips. This is how you do that: First we will create a new database named TestFilegroup. Next we will add a filegroup named Test1FG1 which contains a file named test1dat3.
The next step is to do an alter database modift filegroup readonly command
Here is the complete script

USE master
go

--Create New DB For Testing
CREATE DATABASE TestFilegroup
go


--Create FileGroup
ALTER DATABASE TestFilegroup
ADD FILEGROUP Test1FG1;

--Add file to fileGroup
ALTER DATABASE TestFilegroup
ADD FILE
(
NAME = test1dat3,
FILENAME = 'c:\t1dat3.ndf',
SIZE = 5MB,
MAXSIZE = 100MB,
FILEGROWTH = 5MB

)
TO FILEGROUP Test1FG1

--Make FileGroup ReadOnly
ALTER DATABASE TestFilegroup
MODIFY FILEGROUP Test1FG1 Read_Only;

Use Read_Only not ReadOnly because the keyword READONLY will be removed in a future version of Microsoft SQL Server. Avoid using READONLY in new development work, and plan to modify applications that currently use READONLY. Use READ_ONLY instead.




Now what happens when you try to create a table on filegroup Test1FG1?
USE TestFilegroup
GO
CREATE TABLE abc (id INT) ON Test1FG1

You will see the following error message
Server: Msg 1924, Level 16, State 2, Line 1
Filegroup 'Test1FG1' is read-only.

You can use sys.filegroups and check the is_read_only column to find out if a filegroup is read only
SELECT is_read_only
FROM sys.filegroups
WHERE name = 'Test1FG1'

Here is the result
is_read_only
------------
1




Using NTFS Compression with Read-Only User-defined Filegroups and Read-Only Databases
SQL Server 2005 supports NTFS compression of read-only user-defined filegroups and read-only databases. You should consider compressing read-only data in the following situations:
You have a large volume of static or historical data that must be available for limited read-only access.
You have limited disk space.
