I have a problem, for which I'm sure there is a simple answer but I can't see it.
I've a table called "test" with following rows: id
1000 1000 1000 1000 1001 1001 1002 1002 1003 1003 1003
I want to get the smallest wsid having the smallest amount of rows.
Result set I want is:
wsid rowcnt
----------- -----------
1001 2
The following returns all the rows that have the smallest amount of
rows, but how to get only the smallest wsid?
select wsid, count(wsid) as rowcnt
from test
group by wsid
having count(wsid) = min(count(wsid))
wsid rowcnt
----------- -----------
1001 2 1002 2
Adding wsid = min(wsid) to having clause does not help.
Thank you in advance Received on Thu Aug 16 2001 - 15:26:54 CEST
