Restore all SQL databases in a Directory to Instance using a Script
Have you ever done a sql production server migration to different server for any reason? How many databases you had to backup and restore to the new server? On my previous script (How to backup All Databases in SQL Instance using Script); I shared how to back all dbs to an instance using one script.
Now since we backed up all dbs, we still need to restore them and doing that manually is a very long process. The following query should allow you to restore all SQL databases in a Directory and has the .BAK extension to a SQL instance
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sp_CSS_RestoreDir]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[sp_CSS_RestoreDir]
GO

-- Procedure Name: sp_CSS_RestoreDir
-- Purpose: Restore one or many database backups from a single directory. This script reads all
-- database backups that are found in the @restoreFromDir parameter.
-- Any database backup that matches the form %_db_% will be restored to
-- the file locations specified in the RestoreTo... parameter(s). The database
-- will be restored to a database name that is based on the database backup
-- file name. For example Insurance_db_200305212302.BAK will be restored to
-- a database named Insurance. The characters preceeding the '_db_' text determines
-- the name.
--
-- Input Parameters: @restoreFromDir - The directory where the database backups are located
-- @restoreToDataDir - The directory where the data files (i.e. MDF) will be restored to
-- @restoreToLogDir - The directory where the log files (i.e. LDF) will be restored to. If
-- this parameter is not provided then the log files are restored to @restoreToDataDir.
-- @MatchFileList - set to 'Y' to restore to same directory structure contained in the backup,
-- also allows for secondary data files 'ndf' to to be in a different dir than mdf files
-- @DBName - restore just this one database - selects the latest bak file
--
-- Output Parameters: None
--
-- Return Values:

-- Sample Execution: exec sp_CSS_RestoreDir 'C:\sqldb\sql_backup', 'C:\sqldb\sql_data', 'C:\sqldb\sql_log' (if you use declare/set option then you don't have to use this command to restore)

-- Alternate Execution: exec sp_CSS_RestoreDir 'C:\sqldb\sql_backup', @MatchFileList = 'Y' (if you use declare/set option then you don't have to use this command to restore)
