Table B-5 says that you can do "setObject(n, new Boolean(value),
Types.SMALLINT)" and the driver will convert the Boolean to a SMALLINT.
See section 220.127.116.11 ("Type Conversions Using the Method setObject") in
As far as I know, the driver supports this case correctly.
I suspect that Hibernate is using setBoolean(), or passing a Boolean to
the setObject() variant that does not take a Types constant. In both of
these cases the driver will pass the parameter to the backend typed as a
boolean, which will produce an error like the above if actually needs to
be some other type.
