Hi all,
Im using InfmxCli and i cant execute a query like that:
SELECT a, MAX(b) FROM tabA
GROUP BY a
HAVING MAX(b) = SELECT c FROM tabC
It gives the follow message:
[Informix] [Odbc Informix Driver] General error. Syntax error,
SQLExecute: Failed to execute statement.
If i use:
SELECT a, MAX(b) FROM tabA
GROUP BY a
HAVING MAX(b) = 1
it works, but when i put a select instruction it gives an error.
Anyone can help me?
Thanks in advance, Nuno Pimenta
Query with HAVING
Dont know about Datastage, but the syntax I use for this query in Informix
is:
SELECT a, MAX(b)
FROM tabA
GROUP BY a
HAVING MAX(b) in (SELECT c FROM tabC )
You cannot use = because "select c from tabc" can return more than one row
Hope this helps
Dirk
