Home: Perl Programming Help: DBI: a INTERSECT kind of question

toshesh Novice Feb 9, 2004, 6:17 AM Post #1 of 4 (7495 views) a INTERSECT kind of question Can't Post Hi, I was wondering if anyone know how to perform a database search(query) by matching specified number of colums (not all columns) to intersect with another query and at the same time get the data that doesnt intersect. Something like below: select test1, test2, test3 from test intersect test1, test2, test4 from test;

In PostgeSQL, you could do exactly what you posted and it would work, but in MySQL it gets way complicated. This sort of thing totally depends on which database you are using. -localfilmmaker Spencer Christensen

But you were close. Try this: select test1, test2, test3 from test intersect select test1, test2, test4 from test; -localfilmmaker Spencer Christensen
