Description

The following SQL statement works as expected without an error:
—
update T_Professor set weight_In_B_D = ((((weight_In_B_D + 10) - 5) *
4) / 2) where (id = 1)
—

But the same statement as a PreparedStatement throws an exception:
–
update T_Professor set weight_In_B_D = ((((weight_In_B_D + ?) - ?) *
?) / ?) where (id = ?)
–

–

(The connection is made to an embedded in memory instance.)

The values must be explicitly casted to decimal to get it working (even when the values are set as BigDecimal):
–
update T_Professor set weight_In_B_D = ((((weight_In_B_D + cast(? as decimal)) - cast(? as decimal)) *
cast(? as decimal)) / cast(? as decimal)) where (id = ?)
