Hi!

I've been looking all around without finding. Here's my question : is this possible to do a nested query with DBI/oracle ?

Here's my query : 

SELECT TROUBLE_TICKET_NUM FROM 
(SELECT TROUBLE_TICKET_NUM FROM TICKETTABLE WHERE TROUBLE_TICKET_NUM >
+ '123456789' AND WORK_GROUP='abc' ORDER BY TROUBLE_TICKET_NUM ASC)
WHERE ROWNUM <= 4

This is executed instantly in my Oracle client (toad). But in a script, that just hangs there forever. Basically, it doesn't get to the fetchall_arrayref statement.

$odstthandle = $dbttods->prepare($qry) or die $dbttods->errstr;
$odstthandle->execute() or die $odstthandle->errstr;
$billets = $odstthandle->fetchall_arrayref or die $odstthandle->errstr
+;

Is that even possible to do ? If so any way to troubleshoot whats taking so long ? If not, any alternative than DBI ?

Thanks for your time !
