Hello pgsql listers, I've got a problem that is similar to, but I don't think identical to, a cross tab query. My data looks like: ID | CAT 1 | A 1 | B 2 | A 2 | C So for each ID there may be many CAT (categories). The client wants it to look like: ID | CATS 1 | A,B 2 | A,C Where each ID is unique in the results, and the CAT values are concatenated with a comma separator.
There are about 100 unique CAT values. They only way I can see to do it is programatically with a for loop. But before I do that I wanted to bounce it off the fine minds that inhabit this list.
