Re: Another Query Problem

I tried this query and I couldn't get it to work. It may be that I'm not substituting in proper infd or it may be the version of SQL+ I'm using (for BTW is SQL*Plus: Release 8.1.5.0.0) or if the query is somehow flawed. I would appreciate if anyone else could take a look at this and see if they can make sense of it all. Again, what i'm looking for is a query that will return how many times each value (in this case character strings) appear in 3 columns of a table. (& the additional constraint of only returning the character strings (& the # of occurences) that are greater or equal to 3).

Thanks Again!
