Posted on by
Hi all,
 
I am loading a custom table from a SQL Server view. It contains about 90,000 rows. Is there a way to clear the rows prior to a  new iteration of the dataflow? I have tried to create a unique key for the incoming rows without success. COuld I do it through .net, Powershell, VBS, etc?
