Hi List,
I am having trouble trying to figure out
how to get the result listed at the bottom.
I have 3 tables units, types of units which has a description of the units,
and a table that list associations of the units. I can't figure out
how to do the proper joins. Any pointers would be appreciated.
SELECT us.udevice, ts.descr, ud.udevice, td.descr FROM assoc AS a LEFT JOIN units AS us ON a.src_id = us.uid LEFT JOIN types AS ts ON us.utype = ts.id LEFT JOIN units AS ud ON a.dest_id = ud.uid LEFT JOIN types AS td ON ud.utype = td.id;
Thanks Oliver - that worked perfectly.
