We upgraded to JDBC Build 309 on PostgreSQL 8.0 from
JDBC Build 307 on PostgreSQL 7.4 and setObject now fails
on PGInterval
1)
if myPgInterval != null
Originally code: myPreparedStatement.setObject(i, myPGInterval)
It throws SQLException "Unknown type null"
We tried: myPreparedStatement.setObject(i, myPGInterval, Types.OTHER)
It throws "Unknown type null"
if myPgInterval == null
Original code: myPreparedStatement.setObject(i,myPGInterval)
It throws "setObject(i,null) is not supported. Instead, use setNull(i,type) or setObject(i,null,type)"
We tried: myPreparedStatement.setNull(i, Types.OTHER)
It throws "setNull(i, Types.OTHER) is not supported; use setObject(i,null, Types.OTHER) instead"
We tried: myPreparedStatement.setObject(i,myPGInterval,Types.OTHER)
It throws "setNull(i, Types.OTHER) is not supported; use setObject(i,null, Types.OTHER) instead"
How should setObject be coded with a PGInterval ?
2)
With JDBC Build 309, setObject requires an SQL Type when object == null,
this makes setObject(i, object) useless.
Why do JDBC requires an SQL Type when the same statement can be processed by psql
without the SQL type specified?
Why is a standard JDBC method setObject(i, object) rendered useless?
Is it supported by other DBMS?
Thanks
