Remarks

JetUpdate is the final step in performing an insert or an update. The update is begun by calling JetPrepareUpdate(JET_SESID, JET_TABLEID, JET_prep) and then by calling JetSetColumn(JET_SESID, JET_TABLEID, JET_COLUMNID, [], Int32, SetColumnGrbit, JET_SETINFO) one or more times to set the record state. Finally, JetUpdate(JET_SESID, JET_TABLEID, [], Int32, Int32) is called to complete the update operation. Indexes are updated only by JetUpdate or and not during JetSetColumn.
