Forum OpenACS Q&A: Re: Strange query performance when using <b>UNION</b>

Hmmm.. looks like you could be onto something there. AskTom has an article about this

In 8i the parameter is called _COMPLEX_VIEW_MERGING and it's undocumented. I'll play around a bit with this on test before touching production. This is starting to look quite hairy indeed....

Thanks for the wisdom Dirk!
