Hi. I am developing a site for a gentleman and have to use access as the DBMS. I need to insert some data into the database. Usually when I have one main table (e.g., Users) and need to also insert data into some dependant tables (e.g., Orders) where the ID from Users is a foriegn key of the dependant table, I use the mysql function mysql_insert_id to get the last inserted ID.

I was wondering if anyone had an equivelent way to obtain the last inserted ID from a Jet Access DB? I could just insert it and turn around and do a select getting the largest ID, but that is risky if another gets inserted by another user. Any ideas?

Thanks a lot.

you can have a form/subform pair to solve your problem. You can find lot of examples on using form and subform in Microsoft Solutions sample database.

sorry, but that's not the solution.
I need to convert data from one DB to another - with slightly different sructure. It seems to me that forms help /subform wontin this case http://www.access-programmers.co.uk/ubb/smile.gif

Just an idea, but how about adding a Now() field to the table? That way all you have to do is find the record with the latest value in the Now() field and return the ID...

???

Why not store the LAST INSERTED ID into a public long tye variable each time time a record is created, then you can get the number any time you want it.

Another alternative is to store it in a one record table each time so you can retrieve it in a query without using a function.

The first option is the best as the variable will be stored locally and thus eradicate the risk of another record being entered in the mean time.
