jQuery Intellisense in VS 2008

I have been working with the jQuery in VS 2008 and I needed jQuery intellisense support.
Since the process in not straightforward, I decided to document it here:
1) Install VS 2008 SP1
2) Install VS 2008 Patch KB958502 to Support "-vsdoc.js" Intellisense Files
You can download it for here
3) Download the jQuery-vsdoc.js from the official download page here
Use the Documentation: Visual Studio link.
4) Save the jquery-vsdoc.js file in the same folder of the jquery.js file in your project and make sure its naming prefix matches the jquery file name
5) There is no intellisense support in user controls (ascx) unless the jQuery.js file is included. Since normally we don't want to include the jQuery file in the ascx there is a workaround:


<% if (false) {%>
<% script src="js/jquery.js" type="text/javascript"><% /script>
<% } %>

How to delete a temporary table in TSQL

How to: Restore a SQL Server database with TSQL

The task of restoring a SQL Server database with a TSQL script is as simple as executing the following script:

RESTORE DATABASE [MyDatabase]
FROM DISK = N'C:\Backup\MyDatabase.bak'
WITH  FILE = 1,
MOVE N'MyDataLogicalName' TO N'D:\DatabasesData\MyDatabase.mdf', 
MOVE N'MyLogLogicalName' TO N'D:\DatabasesLog\MyDatabase_log.ldf', 

The only problem with the previous script is that if there are any open connections to the database the following error is generated:

Exclusive access could not be obtained because the database is in use.

To fix the issue one solution is to put the database in single user mode before the backup.

-- Put the database in single user Mode
ALTER DATABASE MyDatabase
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE

-- Restore the Database
RESTORE DATABASE MyDatabase FROM DISK ...

-- Put the database back in multiuser mode
ALTER DATABASE MyDatabase SET MULTI_USER
GO

If this script fails, execute the last statement to put the data base back in multiuser mode.

To simply restore the database use:
-- Put the database in single user Mode
ALTER DATABASE MyDatabase
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE
-- Restore the Database
RESTORE DATABASE MyDatabase FROM DISK = N'C:\Backup\MyDatabase .bak' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
-- Put the database back in multiuser mode
ALTER DATABASE MyDatabase SET MULTI_USER
GO

How To: Change the tempdb data files location

To change the tempdb data files location:
1) Determine the logical file names for the tempdb database.
The logical name for each file is contained in the NAME column.

2)Change the location of each file using ALTER DATABASE.
USE master
GO
ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev, FILENAME = 'E:\DBData\tempdb.mdf')

ALTER DATABASE tempdb MODIFY FILE (NAME = templog,FILENAME = 'E:\DBData\templog.ldf')
GO
3) Stop and restart SQL Server.

Fix: Saving changed to a table not permitted on SQL Server 2008

An error message occurs when you try to save table chnages in SQL Server 2008 Management Studio:
Saving changes is not permitted. The changes that you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created.

This problem occurs when the Prevent saving changes that require the table re-creation option is enabled.

To disable it:
1) Open SQL Server Management Studio (SSMS).
2) On the Tools menu, click Options.
3) Click Designers.
4) Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note that if you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

This is a bug from microsoft, more information here.

when a user is being dropped that owns a schema in the database.

Now locate the schema(s) the user you want to delete is the owner, right click and select properties. In the General you can see the schema owner, change it to the new owner (dbo for example).

When the user you want to delete has no schemas owned you can delete it.
