[Zope] SQL wizard compatible with gadfly?

Dear all, I have 5 tables and I was import it into gadfly database because CVS parsing is too slow (2 minutes per query at P4-1,5Ghz). I was import that tables into gadfly database, but parsing without SQL is slow too. I was try ZVisualQuery from ZDataQueryKit, but gadfly does not accept "JOIN" sql command. So my question is - which ZopeSQL wizard is compatible with gadfly? Many thanks, -- Jaroslav Lukeš -- Tento e-mail nemůže obsahovat VIRY jelikož nepocházi z virózního systému M$ Windows!
