In SMT, When I write SQL statements in the Exdesc: box while I am creating PI tags, why do I need to use the PI types like PI_VALUE and PI_TIMESTAMP and things like that? I tried making tags without that and it did not work, but I restricted the values I selected to be PI_VALUES, then it worked. Why?
