 ==== 2nd usage ====
+The second usage requires the construction of the array ''$override'', which can then be passed into the function. The ADODb values are then set to those values. The function returns null in this case. Best practice for usage of this function is to call it in the first way.
+<code php>
+/*
+ * database connection assumed
+ */
+/*
+ * Start a database transaction
+ */
+$db->startTrans();
+/*
+ * Update some value successfully
+ */
+$db->Execute('UPDATE some_table (field_1) VALUES "abcd");

+ Do some other work, which makes us decide to rollback the transaction
+<code php>
+if ($resultOfWork == false) {
+    $currentStatus = $db->ignoreErrors();
+    /*
+     * Force the transaction to fail
+     */
+    $currentStatus[1] = false;
+    $db->ignoreErrors($currentStatus);
+}
+$db->completeTrans();
