Hi,

There are some schemas missing in test database when compared to production database.
Schema count in production is 50 but in test it is only 30.It is difficult to find out those
missing schemas in test database.
Could you give an alternate method to find out those missing schemas in test database
instead of cross checking one by one in database manually.

Thanks,
Jack

I don't know about you, but I'm quite sure I'd manually find differences in a matter of a couple of minutes (which would, probably, be faster than coding the same thing, which might include creating a database link & writing a query (don't forget debugging)).

What, 50 vs. 30? Print two pieces of paper, sorted alphabetically, and you're done instantly.

[EDIT] If you insist, use MINUS set operator for two

Code: [Select all] [Show/ hide]

select username from all_users

@Jack14, if you are wondering how to get the list of all users, use SPOOL in SQL*Plus to get the result of the query LF suggested. You will get to see the difference of 20 users right away.

For instance, using "diff".
