Description Liangent 2013-09-04 16:59:16 UTC 
Normally it looks sane to write:

wfGetDB(DB_SLAVE)->selectSQLText('objectcache','objectcache.keyname');

but with database prefix set to "pf_", the resulting SQL becomes:

SELECT objectcache.keyname FROM `pf_objectcache`

which doesn't work.
Comment 1 db [inactive,noenotif] 2013-09-08 09:18:57 UTC 
in this case you must not use the full name of the column, because it is not ambigious

As workaround you can set alias yourself:

wfGetDB(DB_SLAVE)->selectSQLText(array( 'oc' => 'objectcache' ),'oc.keyname');
