MSSQL Recover users after restore

Save the below script into a stored procedure, and you can call this after restoring a database, but you can also just copy this into a query.
Don’t forget that the query should be using the newly restored database.

EXEC sp_change_users_login 'report'--See all orphaned users in the database.
DECLARE @OrphanedUsers TABLE
(
  IndexKey Int IDENTITY(1,1) PRIMARY KEY,
  UserName SysName,--nVarChar(128)
  UserSID  VarBinary(85)
)
INSERT INTO @OrphanedUsers
    EXEC sp_change_users_login 'report'

DECLARE @CRLF as nVarChar
    SET @CRLF = CHAR(10) + '&' + CHAR(13)--NOTE: Carriage-Return/Line-Feed will only appear in PRINT statements, not SELECT statements.
DECLARE @Sql as nVarChar(MAX)
    SET @Sql = N''
DECLARE @IndexKey as Int
    SET @IndexKey = 1
DECLARE @MaxIndexKey as Int
    SET @MaxIndexKey = (SELECT COUNT(*) FROM @OrphanedUsers)
DECLARE @Count as Int
    SET @Count = 0
DECLARE @UsersFixed as nVarChar(MAX)
    SET @UsersFixed = N''
DECLARE @UserName as SysName--This is an orphaned Database user.

WHILE (@IndexKey <= @MaxIndexKey)
  BEGIN
    SET @UserName = (SELECT UserName FROM @OrphanedUsers WHERE IndexKey = @IndexKey)
    IF 1 = (SELECT COUNT(*) FROM sys.server_principals WHERE Name = @UserName)--Look for a match in the Server Logins.
      BEGIN
        SET @Sql = @Sql + 'EXEC sp_change_users_login ''update_one'', [' + @UserName + '], [' + @UserName + ']' + @CRLF
        SET @UsersFixed = @UsersFixed + @UserName + ', '
        SET @Count = @Count + 1
      END
    SET @IndexKey = @IndexKey + 1
  END

PRINT @Sql
EXEC sp_executesql @Sql
PRINT   'Total fixed: ' + CAST(@Count as VarChar) + '.  Users Fixed: ' + @UsersFixed
SELECT ('Total fixed: ' + CAST(@Count as VarChar) + '.  Users Fixed: ' + @UsersFixed)[Fixed]
EXEC sp_change_users_login 'report'--See all orphaned users still in the database.
