Tag: Database

This is a complete configurable metascript, prepared to create detach statements, file move statement and re-attach statements for every database in your instance.
You have only to configure the final destination for datafiles and the database list you want to migrate.

The final generated script for every database selected will be something like this (remembar to use ALT-T to use text output mode in Management Studio)

============================================================
  DATABASE: myTestDB
============================================================
 
--  1) DETACH DATABASE
 
USE [master]
GO
ALTER DATABASE [myTestDB] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
EXEC master.dbo.sp_detach_db @dbname = N'myTestDB', @keepfulltextindexfile=N'false'
GO
 
--  2) DATAFILE OS MOVING
 
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB_log.LDF" L:LogPath'
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB.mdf" D:DataPath'
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB_2.ndf" D:DataPath'
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB_3.ndf" D:DataPath'
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB_4.ndf" D:DataPath'
exec xp_cmdshell 'move "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmyTestDB_5.ndf" D:DataPath'
 
--  3) ATTACH DATABASE
 
CREATE DATABASE [myTestDB] ON 
( FILENAME = N'L:LogPathmyTestDB_log.LDF' ),
( FILENAME = N'D:DataPathmyTestDB.mdf' ),
( FILENAME = N'D:DataPathmyTestDB_2.ndf' ),
( FILENAME = N'D:DataPathmyTestDB_3.ndf' ),
( FILENAME = N'D:DataPathmyTestDB_4.ndf' ),
( FILENAME = N'D:DataPathmyTestDB_5.ndf' ) 
FOR ATTACH
GO
