Can you split/explode a field in a MySQL query?

Question

I have to create a report on some student completions. The students each belong to one client. Here are the tables (simplified for this question).

CREATE TAB         


        

Answer 1

There's an easier way, have a link table, i.e.:

Table 1: clients, client info, blah blah blah

Table 2: courses, course info, blah blah

Table 3: clientid, courseid

Then do a JOIN and you're off to the races.
