do you mean to be using the case() function , that produces the CASE expression ? It's a standalone function not part of the "func." construct: http://www.sqlalchemy.org/docs/core/expression_api.html?highlight=case#sqlalchemy.sql.expression.case The error you're getting is due to func.case() just being a generic function, the incoming tuple is interpreted as "send straight to the DBAPI" and then it all goes wrong. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
