How to fix all orphaned SQL Logins



If you do lots of database restores from one server to another you may often come across server logins becoming "orphaned" from their associated database users. There is an easy fix for this by using sp_change_users_login but what if there are multiple logins that have become orphaned?

The cursor below should fix them all for you:

-----------------------------------------
-- Auto fix all orphaned user accounts
-----------------------------------------
DECLARE @SQL VARCHAR(MAX) 
SET @SQL =
       'DECLARE @userVar VARCHAR(30)
              DECLARE users CURSOR
              FOR
              SELECT NAME
              FROM sys.database_principals
              WHERE type = ''s''
                     AND NAME NOT IN (
                           ''guest''
                           ,''sys''
                           ,''INFORMATION_SCHEMA''
                           ,''dbo''
                           )     
              OPEN users   
              FETCH NEXT
              FROM users
              INTO @userVar 
              WHILE @@FETCH_STATUS = 0
              BEGIN
                     EXEC sp_change_users_login ''auto_fix''
                           ,@userVar
                     FETCH NEXT
                     FROM users
                     INTO @userVar
              END   
              CLOSE users
              DEALLOCATE users'

EXEC(@SQL)

Generate scripts to attach multiple databases

There is a handy little "by product", if you like, when running queries which means you can quickly generate scripts to do different things. Below is an example of generating multiple "attach" commands that you can copy from the results pane into the main SSMS window for execution. I have found this very handy in the past:


SELECT 'CREATE DATABASE ['+name+'] ON ( FILENAME = N''F:\MSSQL\Data\'+name+'.mdf'' ), ( FILENAME = N''E:\MSSQL\Log\'+name+'_log.ldf'' )  FOR ATTACH GO ' FROMmaster.dbo.sysdatabases WHEREnamenotin('master','msdb','model','tempdb')
ORDERBYname

How to move the Microsoft Assessment and Planning Toolkit (MAP) database to a different drive

The Microsoft Assessment and Planning Toolkit (MAP) is a very useful tool for scanning your network to find instances of SQL Server plus all manner of detailed information about the installed product, OS and hardware it sits on.

There is an issue with it the database it uses to store the data it collects, however. Assuming you don't have an instance called MAPS on your server, the product will install using LocalDB (a cut down version of SQL Server Express) and puts the databases on your C: drive. If you then scan a large network you could easily expand the database to 10GB which may cause issues on a server when that drive is often one of the smallest. However, there is a simple solution: connect to LocalDB using Management Studio, detach the databases, move to a different drive, set permissions on the new location if required and reattach the database. How do you connect to LocalDB? Here you go:

Connect to (localdb)\MAPTOOLKIT

The Purge SQL Agent Job for MDW takes a long time to complete

I use the dbWarden alerts to inform me if a SQL job is taking longer to complete than normal and I got one this morning:
I noticed by looking at the history this purge job was gradually taking longer and longer to complete each day since I installed it again (see mylast post on this):
