Hi guys,

I have two table a "Module" table and a "StaffModule" I'm wanting to display a list of modules by which staff are present on the staffmodule mapping table.

I've tried

from Module join Staffmodule sm with ID = sm.MID

with no luck, I get the following error

Path Expected for join!

however I thought I had the correct join too allow this but obviously not can any one help

StaffModule HBM
