That would not help Daniel, because there is no cast here. You've got
an untyped string literal which is going to be directly interpreted as
a constant of the destination column's datatype.
There are any number of easy ways to fix this if we were allowed to
change the SQL being spit out by the application ... but that's exactly
what he doesn't feel he can do.
