Hi Friends,
I have 10 Databases .
Irefresh these databases from PROD to TEST server.

I need to automate the find and fix orphand users task.
Can any help me in getting the script for this.
Here i want to use update_one to fix the orphand user...bacause my task is to map the existing logins to the user...no need to create logins.
Breif information.

Hi Sam,

Are you able to recreate the logins on the TEST server so the SIDs are the same as the PROD? This would then remove the need to do this.

You probably already know but can reverse engineer CREATE LOGIN statements for logins that include their SID and hashed password using sp_help_revlogin, as per below article:

here's the basics of it: generate the orphans from the meta data:

/*--Results

ALTER USER [z_AppDB_reports] WITH LOGIN = [z_AppDB_reports];

ALTER USER [medical] WITH LOGIN = [medical];

*/

SELECT 'ALTER USER ' + quotename(dbloginz.name) + ' WITH LOGIN = ' + quotename(svloginz.name) + ';'

from sys.database_principals dbloginz

LEFT OUTER JOIN sys.server_principals svloginz

on dbloginz.name = svloginz.name

WHERE dbloginz.type IN ('S')

AND dbloginz.name NOT IN('dbo','guest','INFORMATION_SCHEMA','sys')

and svloginz.name is not null and dbloginz.sid <> svloginz.sid

to do it as a single script, server wide, you'd have to add a cursor i guess, but it's certainly doable.

The best way to do this is to script out the users and their permissions while the test databases are in a good state.

Then:

1. restore from PROD

2. drop all prod users in the databases

3. create all the test users in the databases and grant them their permissions
