That said I know how to do this in MySQL. After you have done

  $cursor = $dbh->prepare("insert into table (a, b) values (?, ?)");
  $cursor->execute($a_var, $b_var);
[download]

  $id = $dbh->{mysql_insertid};
[download]

In a previous version of DBD::mysql the variable was just $dbh->{insertid}.

Don't try to get the last inserted id by "select max(id) from table" this will work short term, but get you into no end of trouble later. You could make it work by locking the table before your insert I guess.

It would be useful if this was standardised in DBI if possible. I personally build all my tables using autoincrementing id's and $dbh->{mysql_insertid} for joining them.

Look at your documentation for DBD::DB2 and see if it offers anything similar!

Okay, a co-worker of mine finally tracked down the answer. Just posting here in case any one else is interested in the answer:

1. Turn off auto-commit ($dbh->{'AutoCommit'} = 0)
2. Do insert
3. SELECT id FROM table WHERE id = INTEGER(IDENTITY_VAL_LOCAL())
4. Commit changes

Naturally, id is the field that is auto-incremented and table is the table you just inserted into.

Share and Enjoy.
