Hi,
I'm using JSDK 2.0 and IBM JDK 1.3 on RedHat Linux 6.2
As i test my servlet, I got errors saying count(*) column not found in a query like this
SELECT COUNT(*) FROM MyTable
in my rs.getint("COUNT(*)"); in oracle it works fine, in postgresql it doesn't. how should i handle aggregate functions in SQL then?
Thanks

What version of rostgres do you use?
SELECT COUNT(*) FROM MyTable works pretty well in postgres 6.5.1 and
later.
Perhaps problem is in java?

Offhand I'd guess that the returned column heading is "count" not
"COUNT(*)". Use an AS clause if you want to be sure about the
column heading of a SELECT result...

Hello
Try this way:
SELECT COUNT(*) as no FROM MyTable
rs.getint("no");
Or
SELECT COUNT(*) FROM MyTable
rs.getInt(0); (or (1))
