Question

I have two tables. One is a table of users with a unique id field, and the other is a table of data, with a column that holds the user id of whoever generated that piece of data.

I want to do something like SELECT data,genned_by FROM datatable; but I want to replace the results for genned_by with SELECT username FROM users WHERE id = genned_by

So that the results from the query changes the userid into a username that corresponds with the other table.

I did some research and figured INNER JOIN might be what I’m looking for, but I’m left very unsure of how to use it after reading it. Help?

Answer 1

SELECT datatable.data,users.username 
FROM datatable, users
WHERE users.id = datatable.genned_by
