$groupPairs = $this->_getDb()->fetchPairs(' SELECT group_id, group_name FROM apms2_group WHERE group_id IN (?) ', $groups);
$groups is '1,2'
If I replace IN (?) with IN (1,2) (for testing) it works properly and fetches multiple pairs. But if I use a prepared statement ($groups is also 1,2) it returns the first value only.
I've tried Zend_Debug::dump to ensure $groups is correct, it is.
Also doesn't work with:
WHERE group_id IN (' . $this->_getDb()->quote($groups) . ')
