$this->db->simple_query();
===========================
-This is a simplified version of the $this->db->query() function. It ONLY
-returns TRUE/FALSE on success or failure. It DOES NOT return a database
-result set, nor does it set the query timer, or compile bind data, or
-store your query for debugging. It simply lets you submit a query. Most
-users will rarely use this function.

+It returns whatever the database drivers' "execute" function returns.
+That typically is TRUE/FALSE on success or failure for write type queries
+such as INSERT, DELETE or UPDATE statements (which is what it really
+should be used for) and a resource/object on success for queries with
+fetchable results.
+
+::
+
+ if ($this->db->simple_query('YOUR QUERY'))
+ {
+ echo "Success!";
+ }
+ else
+ {
+ echo "Query failed!";
+ }
+
+.. note:: PostgreSQL's pg_exec() function always returns a resource on
+ success, even for write type queries. So take that in mind if
+ you're looking for a boolean value.
