Question

I have two tables…

groupid   membership_list   managerid
-------------------------------------
0         /0//1//2/         2
1         /2/               2

userid    username
------------------
0         ben
1         tom
2         dan

I’d like to display a table to for example the user ‘ben’ that is a list of the groups they are a member of that looks like this…

groupid   membership_list   managername
---------------------------------------
0         /0//1//2/         dan

.. so basically replacing ‘manager_id’ with the username for that id. I’ve been hacking away at this but I can’t work it out – my SQL skills are clearly a bit lacking – how can I do this?

SELECT groupid, membership_list, managerid FROM blah WHERE membership_list LIKE '%/?/%'

… is about as far as I’ve got.

Answer 1

SELECT t1.groupid, t1.membership_list, t2.username
FROM table1 t1
INNER JOIN table2 t2 ON t1.managerid = t2.userid

That should do it. Or am I missing something here??
