No version of iBATIS has ever actively converted types. If it worked in
iBATIS 2, it was strictly by luck. It was never a feature though.
You shouldn't need to specify the JDBC type in the example you give though,
because it's not nullable (that query would be invalid with a null value).
You would only get that error if you actually pass a null into the query.
Because Java is strongly typed, iBATIS embraces that, while hopefully
striking a balance of simplicity and avoids duplicate type definition where
possible.
