Some months ago i wrote about retrieving auto generated values with JDBC from an Oracle Database: JDBC: Get autogenerated keys on a Oracle DB.
The solution i presented in the previous article doesn’t run in a Oracle Java Stored Procedure.
To accomplish this, use a callable statement like this:
final String sql = "BEGIN INSERT INTO foobar(id, b) VALUES (id.nextval, ?) RETURNING id INTO ?; END;"; CallableStatement cs = connection.prepareCall(sql); stmt.setString(1, "bar"); stmt.registerOutParameter(2, Types.INTEGER); stmt.executeUpdate(); rv = rs.getInt(2); |
This way you get the id generated by the sequence id without first selecting and then using it.
