Remarks
This method initializes an iterator to point to the beginning of a collection. If this method is called for same Oracle Database 10g collection instance, then this method resets the iterator to point back to the beginning of the collection. The OraCollection object automatically reinitializes the iterator when the underlying collection changes due to a dynaset row navigation or a parameter Refresh method.
After you call the InitIterator method, you need to call the IterNext method or the first element in the collection repeats an extra time.
