List pgsql-sql
Hi,

I tried the write up the following SQL statement:

result1 from sql1 = (1,2,3,4,5)
result2 from sql2 = (4,5)
result3 = result1/result2 (or is it result2/result1) = (1,2,3)

What do I have to do to get the (1,2,3) result?  I tried "query EXCEPT
query", but it seems like EXCEPT needs both tables in queries to be of
the same number of columns and column types.  And (any, all, exist)
doesn't seem to be a right solution.

Thanks for help.
