What he's doing is joining a table that doesn't share a key with the table to which it is being joined, but does relate to the data.
e.g. we have business, divisions and people tables, where people belong to a division, and divisions belong to a business. Also, people belong to a business (in his model).
He is (I think) doing something like this:
Code:
SELECT * FROM people JOIN business ON business.id = 1 WHERE people.business_id = 1
It would work, but I question the model, even if I did make it up myself.
If this is what is being planned, then the manual will tell you how to turn off backticks for certain functions (e.g. select and query, I think).
