Re^2: Query takes 895ms in TOAD but 42s in DBI

Thanks for the replies. I will get round to profiling it when i can get the module installed.

I cant use coalesce as i dont have access to the schema. Even just doing the query without printing to stdout or files takes 42 seconds.

regards, Joe

COALESCE is a function you put into your query that takes the first non-NULL value. As for what's going on ... You said this returns a cursor. What happens in TOAD if you subsequently run through all the rows in the cursor? I suspect that DBD::Oracle is doing just that while TOAD isn't. My criteria for good software: Does it work? Can someone else come in, make a change, and be reasonably certain no bugs were introduced?	[reply]
