Perform a conditional update & insert

Perform a conditional update & insert

 Components Required: Data Flow Task, Conditional Split, Lookup Transform or Merge Join, OLE DB Command Transform

Solution: Use the lookup Transform or Merge Join to detemine if the row exists on the destination and ignore a failed match. If the row yields blank
on the key, then you know the row should be inserted into the target (by Conditional Split). Otherwise, the row is a duplicate or an update. Determine if the row
is an update by comparing the source value to the target value in the Conditional Split. The update can be done by an OLE DB Command Transform or by loading the data
into a staging table.
