Error receiving from socket when data truncation occurs

Question

I am using a PreparedStatement that has a "character" column of a set length (2). It also has a constraint set up of valid entries (H, AS, AR).
When I put valid data into the field, the update works fine. If I enter invalid data of the correct length it gives me the constraint error. However if I put an entry that is too long (and of course is not valid), I get the socket error. I am using setString since there is no setChar, which seems to work fine except in this situation.
My prepared statement has 41 fields to "set". If I cut the number of
fields down to 26, I start getting the CLI0109E String data right truncation. SQLSTATE=22001 error on the field in question. If I set 27 fields on the PreparedStatement, the program never returns from the
executeUpdate();
Any sugguestions?

Answer 1

Validate the length before putting it in the statement.
