SQL script to “copy” a database

Question

I want to write a SQL script that will copy a database on the same server. I could do a backup/restore, but I think it might be faster to just \"copy\" somehow. Does anyon

Answer 1

Here is a version of the code Tony posted which works in SQL Server 2005

USE master
GO
-- the original database (use 'SET @DB = NULL' to disable backup)
DECLARE @DB varchar(200)
SET @DB = 'GMSSDB'
-- the backup filename
DECLARE @BackupFile varchar(2000)
SET @BackupFile = 'c:\temp\backup.dat'
-- the new database name
DECLARE @TestDB varchar(200)
SET @TestDB = 'GMSSDBArchive'
-- the new database files without .mdf/.ldf
DECLARE @RestoreFile varchar(2000)
SET @RestoreFile = 'c:\temp\backup'
-- ****************************************************************
-- no change below this line
-- ****************************************************************

DECLARE @query varchar(2000)
DECLARE @DataFile varchar(2000)
SET @DataFile = @RestoreFile + '.mdf'
DECLARE @LogFile varchar(2000)
SET @LogFile = @RestoreFile + '.ldf'
IF @DB IS NOT NULL
BEGIN
SET @query = 'BACKUP DATABASE ' + @DB + ' TO DISK = ' + QUOTENAME(@BackupFile, '''')
EXEC (@query)
END
-- RESTORE FILELISTONLY FROM DISK = 'C:\temp\backup.dat'
-- RESTORE HEADERONLY FROM DISK = 'C:\temp\backup.dat'
-- RESTORE LABELONLY FROM DISK = 'C:\temp\backup.dat'
-- RESTORE VERIFYONLY FROM DISK = 'C:\temp\backup.dat'
IF EXISTS(SELECT * FROM sysdatabases WHERE name = @TestDB)
BEGIN
SET @query = 'DROP DATABASE ' + @TestDB
EXEC (@query)
END
