View OrphanedUsersFixByName.sql
/* NJohnson9402 / natethedba.wordpress.com
An example of how to check for orphaned database users (users that do not map to a server login).
Basically the idea here is to take the output of `sys.sp_helpuser` and utilize it to find & fix.
There are much cooler ways out there, such as dbatools.io/functions/repair-dbaorphanuser/, but
I have occasionally seen these not work in odd situations. Plus, if your login names and user names
don't exactly match, this method could be extended to enter custom mappings-- you'd simply add a new
column to #HelpUser, say [NewLoginName], and use that in the 'fix-it' statement-generator query.

View RenameDatabaseByBackupDetachAttach.sql
/* NJohnson9402 / natethedba.wordpress.com
An example of how to rename a database by work-around involving backup, restore, detach, attach.
Basically the idea here is that 'OriginalDB' is in heavy use, and can't tolerate much "downtime",
but "readonly time" is OK for a bit.
Drive letters for clarification in this case: 'D' for slow data, 'L' for slow tlog,
'E' for fast data, 'M' for fast tlog. The 'fast' storage system is our destination.
