Home -> Community -> Mailing Lists -> Oracle-L -> RE: Union quries: INTERSECT, MINUS, etc
At a previous job, I used MINUS as part of a package to perform
automated testing of transaction processing. Compared actual result set
with expected result set via minus. IF rows returned then if failed and
returned rows were written to error table for review. Worked well for
what we needed it to do.

Subject: Union quries: INTERSECT, MINUS, etc
I'm doing research for an article on union queries. I'm interested in finding examples of problems that were solved using UNION, UNION ALL, INTERSECT, or MINUS, with the latter two being of special interest because I don't see them used very often. If you can think of an interesting problem you've solved using one of these keywords, I'd love to hear about it.
