you have joined pid on cid, in your dummy table it worked correctly, because pid and cids are same on relation table, but you are doing wrong, you should join cids from both table

No, no, and once again no. Why did you do the query in one long line? This absolutely unreadable after few words of query... you should do enter after every SQL keyword.

Shouldn't that inner join condition be "p.c_id"?
Thanks!
