php - How to inner join 3 tables using mySQL? -


i have joined 2 tables below correctly

select m.id mid, c.id cid members m inner join companies c on m.id=c.id

and wanted add 3rd table also, can not working.

select m.id mid, c.id cid, u.id uid members m inner join companies c on m.id=c.id inner join users u on m.id=u.id

what missing here?

switch them inner joins left joins.

if use inner join, , result not exist in 3 tables, excluded, appearing fail/not return results.

select m.id mid, c.id cid, u.id uid  members m  left join companies c on m.id=c.id  left join users u on m.id=u.id

that should take care of issues seeing.
