Can i run a query and use the delete statement_**


Yeah you can but only against table items.

ex: I have a data table named TestDT and want to clear its contents


additionally, you can use update queries to update properties on objects

ex: I want to update a points alarm source where it's ID = 12345

UPDATE CPointAlg SET AlarmSource = 'Test Pt Alarm Source' WHERE ID = 12345

I don't believe you can do a DELETE from against property/metadata values so you'd end up running an update and setting the value to empty ( '' )


Just to expand on the above comment, look up Server.Query in the help for how to actually execute the queries.
