[Zope] formatting tuple to feed to mysql

I'm have a tuple that I want to pass to a zSQL query to so I can based on items in the tuple. I get the sequence from a zSQL query that selects a single field, and I'm postprocessing it with the following: <dtml-let SelectedIDs="[ai[0] for ai in queries.selectDOdocIDs().tuples()]"> Which puts the sequence in brackets like this: [211, 873, 515, 516, 589] but mysql seems to want them in parenthesis... because when I try this select ThemeWords.* from DocThemes, ThemeWords where DocThemes.DocID in <dtml-var SelectedIDs> and DocThemes.ThemeID = ThemeWords.ID I get a KeyError. Also, is it possible to pass a list using dtml-sqlvar? thanks -- David
