MySQL, to correctly render the SET clause among multiple columns with the same name across tables. This also changes the name used for the bound parameter in the SET clause to "<tablename>_<colname>" for the non-primary table only; as this parameter is typically specified using the :class:`.Column` object directly this should not have an impact on applications. The fix takes effect for both :meth:`.Table.update` as well as :meth:`.Query.update` in the ORM. [ticket:2912]
