백업 파일로부터 DB를 새로 복원할 때 곤란한 점은 일일이 DB의 User와 SQL서버의 Login을 매핑해 줘야 한다는 점이다.

아래 스크립트를 사용하면 이 작업을 한번에 처리할 수 있다.


1. User와 Login의 Sync가 맞지 않는 내역이 있는지 확인

DECLARE @nvcCollation sysname;

DECLARE @nvcStmt nvarchar(4000);

DECLARE @tblTemp table (

       DBName sysname NOT NULL,

       UserName sysname NOT NULL,

       LoginName sysname NOT NULL

);

 

SET @nvcCollation = CAST(DatabasePropertyEx('master', 'Collation') AS sysname);

SET @nvcStmt = N'

USE [?];

SELECT ''?'', A.name, B.loginname

FROM sys.sysusers A

       INNER JOIN master.dbo.syslogins B ON A.name COLLATE ' + @nvcCollation + N' = B.Name

       INNER JOIN master.dbo.sysdatabases C ON C.name = ''?''

WHERE A.issqluser = 1 AND (A.sid IS NOT NULL AND A.sid <> 0x0)

       AND SUSER_SNAME(A.sid) IS NULL

       AND (C.status & 32) =0 --loading

       AND (C.status & 64) =0 --pre recovery

       AND (C.status & 128) =0 --recovering

       AND (C.status & 256) =0 --not recovered

       AND (C.status & 512) =0 --offline

       AND (C.status & 1024) =0 --read only

ORDER BY A.name';

 

INSERT @tblTemp EXEC sp_msforeachdb @nvcStmt;

 

SELECT * FROM @tblTemp;

 

2. 위 스크립트에서 레코드가 반환된다면 => User와 Login을 Sync해 주기

DECLARE @nvcCollation sysname;

DECLARE @nvcStmt nvarchar(4000);

 

SET @nvcCollation = CAST(DatabasePropertyEx('master', 'Collation') AS sysname);

SET @nvcStmt = N'

USE [?];

DECLARE @nvcUserName sysname;

DECLARE @nvcLoginName sysname;

 

DECLARE SyncDBLogins CURSOR FOR

       SELECT A.name AS userName, B.loginname AS loginName

       FROM sys.sysusers A

             INNER JOIN master.dbo.syslogins B ON A.name COLLATE ' + @nvcCollation + N' = B.Name

             INNER JOIN master.dbo.sysdatabases C ON C.Name = ''?''

       WHERE A.issqluser = 1

             AND (A.sid IS NOT NULL AND A.sid <> 0x0)

             AND suser_sname(A.sid) IS NULL

             AND (C.status & 32) =0 --Loading

             AND (C.status & 64) =0 --pre recovery

             AND (C.status & 128) =0 --recovering

             AND (C.status & 256) =0 --not recovered

             AND (C.status & 512) =0 --offline

             AND (C.status & 1024) =0 --read only

       ORDER BY A.name;

 

OPEN SyncDBLogins;

 

FETCH NEXT FROM SyncDBLogins INTO @nvcUserName, @nvcLoginName;

 

WHILE @@FETCH_STATUS = 0

BEGIN

       EXEC sp_change_users_login ''update_one'', @nvcUserName, @nvcLoginName;

    FETCH NEXT FROM SyncDBLogins INTO @nvcUserName, @nvcLoginName;

END;

 

CLOSE SyncDBLogins;

 

DEALLOCATE SyncDBLogins;'

 

EXEC sp_msforeachdb @nvcStmt;
