Bug with wrong SQL

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') AND uid=4 AND type='advimage'' at line 1 query: SELECT nid FROM drgr_node WHERE nid in() AND uid=4 AND type='advimage' в файле /www/sites/all/modules/advimage/advimage_ref/advimage_ref.module в строке 206.

We need check array is empty there while doing implode and do not do db_query() if nothing to select.
