in reply to Last Insert ID in MS Access

You may be able to run

and pass that through to the underlying table. I found it by googling for MS Access and last insert id. One would think the DBD::ODBC documentation should help too, but I found it a bit opaque on this topic. In many advanced SQL dialects you can also say something like
INSERT INTO MyTable (x,y) VALUES (1,2) RETURNING rowid;
Then retrieve the rowid by fetching from the statement handle, if the DBI driver permits this.

    This article suggests that the correct syntax is SELECT @@IDENTITY, and that you should open a second connection to get it. This is presumably problematic with multiple users, so it is as effective (and unreliable) as MAX(ID) would be. I think you could probably lock the table for update and unlock the table after getting the last id.

      I think you'll find it doesn't work if run in a "second connection". I think you just need to ensure it is run as a new statement in the same connection after any outstanding commit.
