All of this pertains to PostgreSQL 7.1.3 and the jdbc3 development driver that I downloaded today and also the stable driver.
I am using an updateable ResultSet and insertRow() to insert a row, which works fine.
I then do a refreshRow() and try to retrieve the auto-generated primary key, which doesn’t work. I just get back a null value. I am currently using the oid to re-select the row as a workaround, but want a database-independent way of getting the key.
Sample code:
ResultSet uprs = stmt.executeQuery("SELECT * FROM login WHERE 1=0");
uprs.moveToInsertRow();
uprs.updateObject(“email”, email);
uprs.insertRow();
uprs.next();
uprs.refreshRow();
String loginId = uprs.getString(); // returns null
Note that the same thing happens if I leave out the ‘uprs.next()’. (As an aside, this is a bug because the refreshRow() should fail if next() is not called; the java docs state that refreshRow() should fail on the insert row).
Can anyone confirm that the code I’m using should return the generated primary key from the database? I’ve looked at the driver code (AbstractJdbc2ResultSet.java) and couldn’t see why this wasn’t working.
Thanks,
Joel
