Query : Running A Job/step In A Loop For ALL Databases

Hi,

I've written a job to export user and database permissions for all
d/b's on a server. As you can see below, the T-SQL commands are the
same for each d/b. Can anyone assist with regard to re-writing this so
that any new d/b's added do not require ammending the job (loop)?

Thx,

GC.

use master
go
SELECT db_name()
EXEC sp_helpuser
EXEC sp_helprotect NULL, NULL, NULL, 'o s'
use msdb
go
SELECT db_name()
EXEC sp_helpuser
EXEC sp_helprotect NULL, NULL, NULL, 'o s'
use test1
go
SELECT db_name()
EXEC sp_helpuser
EXEC sp_helprotect NULL, NULL, NULL, 'o s'
use test2
go
SELECT db_name()
EXEC sp_helpuser
EXEC sp_helprotect NULL, NULL, NULL, 'o s'
