How to generate scripts to alter location of all databases

This is is a handy piece of TSQL code which generates a list of TSQL commands that can be used to alter the location of all user databases to the path specified. It assumes that the filenames for the data file and log file will match the database name plus ".mdf" for the former and "_log.ldf" for the latter.

This can be executed while the SQL service is running and will only take effect after it has been restarted. You will of course have to physically copy the files to the new location when the service is down.


USE master;
GO

SELECT
'ALTER DATABASE [' + name
+ ']
MODIFY FILE ( NAME = [' name + '], FILENAME = ''F:\MSSQL\Data\' + name + '.mdf'' );
ALTER DATABASE [' + name
+ ']
MODIFY FILE ( NAME = [' + name +'_Log], FILENAME = ''E:\MSSQL\Log\' + name + '_Log.ldf'' );
GO
'
FROM sysdatabases
WHERE [sid] <> 0x01
ORDER BY name

How to move the Microsoft Assessment and Planning Toolkit (MAP) database to a different drive

The Microsoft Assessment and Planning Toolkit (MAP) is a very useful tool for scanning your network to find instances of SQL Server plus all manner of detailed information about the installed product, OS and hardware it sits on.

There is an issue with it the database it uses to store the data it collects, however. Assuming you don't have an instance called MAPS on your server, the product will install using LocalDB (a cut down version of SQL Server Express) and puts the databases on your C: drive. If you then scan a large network you could easily expand the database to 10GB which may cause issues on a server when that drive is often one of the smallest. However, there is a simple solution: connect to LocalDB using Management Studio, detach the databases, move to a different drive, set permissions on the new location if required and reattach the database. How do you connect to LocalDB? Here you go:

Connect to (localdb)\MAPTOOLKIT

Generate scripts to attach multiple databases

There is a handy little "by product", if you like, when running queries which means you can quickly generate scripts to do different things. Below is an example of generating multiple "attach" commands that you can copy from the results pane into the main SSMS window for execution. I have found this very handy in the past:


SELECT 'CREATE DATABASE ['+name+'] ON ( FILENAME = N''F:\MSSQL\Data\'+name+'.mdf'' ), ( FILENAME = N''E:\MSSQL\Log\'+name+'_log.ldf'' )  FOR ATTACH GO ' FROMmaster.dbo.sysdatabases WHEREnamenotin('master','msdb','model','tempdb')

The AcquireConnection method call to the connection manager failed with error code 0xC0202009

I had one of those annoying problems with executing a SSIS package that took up most of the morning today (and a couple of hours yesterday) where you get an error which many people have had, but none of their solutions work. I guess it is such a generic error code it can relate to many different issues hence dozens of different (wrong) suggestions. What confused matters was that although it completed successfully in SSDT, it failed when being validated on our newly created SSISDB Catalog. I didn't know whether it was a problem with the package and/or its parameters or the SSISDB Catalog installation or Environment.

If you haven't set up an Integration Services Catalog (a new feature of SQL 2012) yet I definitely think it is worth looking at. I found an excellent guide here that takes you through it all.

In our case we had two connection managers, the source was a table in a SQL Server 2012 database and the destination a table in an Access 2010 database. The server with the Int…
