In some of my previous posts I explained the undocumented stored procedures "sp_msforeachdb" and "sp_msforeachtable" that allow you to massively perform changes on all databases and tables within a SQL Server instance.
But isn't it handier to generate dynamic T-SQL for doing that? I believe it is!
By using some of the catalog views in SQL Server 2005 or later you can easily do that.
The idea is to use a basic SELECT statement and then dynamically build the T-SQL expression that eventually will generate the desired T-SQL code.
Here are some examples (before running the code, right-click in the query window, then select "Results To" and finally "Results to Text"):
Example 1: See the physical files used for each database
Example 2: Change the schema owner for all tables within a database
Example 3: Change the schema owner for all stored procedures within a database
Example 4: See all the views for each database
Example 5: Change the compatibility level for all the databases to 100 (SQL Server 2008)
Example 6: Set all the databases to READ ONLY mode
Example 7: Set all the databases to READ/WRITE mode
... and the list goes on!
When using this technique along with the information retrieved from the catalog views, the possibilities are endless!
Yes, you still need to manually execute each generated T-SQL statement but the good thing is that the statements are being generated dynamically and by manually executing them, you have more control over your SQL Server instance.
I hope this helps!
Until next time!
