Why might this be? If I omit count(*) from the query it runs fine, or if I use count(*) in a query involving only a single table, it also works.
try this: select foo.id, bar.name, count(*) as cnt from foo, bar where (foo.id = bar.id) group by foo.id
The returned columns from an SQL query have to be named something that Zope can deal with (and have to be uniquely named).
Hmmm... I did what you suggested and am still getting the same error message. Maybe this is a bug in ZMySQLDA? As a workaround, I wrote an External Method that uses the python MySQL module directly to execute the query, without problems. --Rick
