I guess my code is more messed up than I thought. I'll try and clarify
your points:
*What am I trying to achieve?*
In the db there are people (given by the auth_user table). From those
people there are ones who are hierarchically above them and supervise
them.They are called Supervisors. All people have mobile and phone
extensions(numbers) . As far as my query goes, I'm getting the Supervisor'
numbers and the people's numbers associated with the Supervisor. What I'm
trying to accomplish: returning only the Supervisor' numbers.
*Would it make more sense to have it like this?*
I'm curious,why would a second table(extension_member) be needed?I think I
will also need the extension_number in the 'extension' table since that
table stores all the phone and mobile extensions.
*Why would you check the first name and last name when you already compared
the ID with person?*
Now I am the one a bit confused. The comparison between the ID and the
person was to connect both tables and then I would filter by the user I
wanted. But now I'm not sure If I've been doing this correctly...?
*Why would you use "like" for an integer field?*
It's the only way I know to check if a number begins as 9 or ~9 . Is there
a simpler/optimised way?Also, as an aside, is there a way to use regular
expressions in queries?
Thank you for all the help!
