In MSSQL there is a command called SCOPE_IDENTITY() which returns the id of the last inserted row. There is probably something similar in whatever dbms you are using.

Otherwise I would need some more information about our environment.

How can I get efficiently the id of the last insterted row?
A the moment I am using :
SELECT MAX(id) from table.
Which isn't efficient.

How can i do it more efficiently but stay database agnostic.
