Why do you want prefixes on all your tables? This is generally not a best practice. If the idea is to group them it would be better to use a schema instead of prefixes.

If you are deadset on doing this then I would use sys.tables to help you build the sql.

SELECT 'aaa_' + name FROM sys.tables T WHERE type = 'U'

Sorry, I was not clear enough. I need to update table name.

From TableA, TableB to aaa_TableA, aaa_TableB.

Thanks.

You do realize that this will break every piece of code you have, correct?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

well you alreayd got the advice that this is a bad idea, but here you go: you know that this will break any views, functions or procedures referencing these tables, of course:

SELECT

'EXECUTE sp_rename '''

+ schema_name(schema_id)

+ '.'

+ name

+ ''',''aaa_'

+ name + ''';'

FROM sys.tables T WHERE type = 'U'
