How many nested SELECT's

[JHausmann]

It would seem it's going to be application specific. I do not know the Access limit but SQL server 6.x can access up to 16 tables, total, at one time (7.0 can do 32). This means the total of tables in the from clause from *any* query (main or sub). I would guess that Access would be no greater than SQL Server. I could be wrong.

Thanks!
