Using sp_MsForEachDb and sp_MsForEachTable Together

Ever wanted to run a T-SQL command on every user table in every user database? Here's how to nest the undocumented sp_MsForEachTable system stored procedure inside the undocumented sp_MsForEachDB system stored procedure.

DECLARE @Sql NVARCHAR(4000) = 
      'IF EXISTS (SELECT * FROM sys.databases WHERE name = ''''#'''' AND owner_sid = 0x01) RETURN '
    + 'RAISERROR(''''Reclaiming space on table ' + QUOTENAME('#') + '.?'''', 10, 1) WITH NOWAIT '
    + 'USE ' + QUOTENAME('#') + ' '
    + 'DBCC CLEANTABLE(''''#'''', ''''?'''', 10000) WITH NO_INFOMSGS '

SET @Sql = 'USE ' + QUOTENAME('#') + ' EXEC sp_MsForEachTable ''' + @Sql + ''''

EXEC sp_MsForEachDb @Sql, @replacechar = '#'

The trick is the @replacechar parameter to the sp_MsForEachDb stored procedure: it's how we keep the placeholders for the database and the table separate. If there's an easier way, I'd love to see it.

Rebuild All Indexes on All Tables

Here's a small script to rebuild all the indexes on all the tables in a given database:

EXEC sp_MsForEachTable 'USE [YourDatabase]  PRINT ''?''  DBCC DBREINDEX (''?'', '' '', 70)'

Be sure to read Books OnLine about "DBCC DBREINDEX" - it's probably not something you want to do during peak hours.
