Syntax COUNT + HAVING in Informix

Hi,

I try to do the following query (which I thought is plain SQL), but it results in an error:

SELECT person_id
FROM job_function
GROUP BY person_id
HAVING COUNT(person_id) > 1

(IN NL: Give me all person_id's of those rows in the table that have this person_id more than once, which means, "Give me all persons with more than one function").

The database complains that the syntax is not OK. It isn't usefull, but when I put a distinct inside the COUNT, the answer of course is wrong, but the syntax seems right.... It seems the problem is a COUNT(field) is not supported, whereas a COUNT(*) is supported.

The database used is a very stripped Informix that was delivered with the Netscape Enterprise 2.0 webserver, with LiveWire Pro....

I think it's just a difference in syntax....

Cheers,


George

George,

I have tried it with a Access Database via ODBC and the syntax you use works with me fine! So don't make any typing errors!!

Maybe you should try to use COUNT(*) instead of using COUNT( person_id) the result should be the same.

Well, the answer stinks, but what the heck (hack). Basically you're right.
