Clearing the MDS tables of data

Hi All,

I'm new to MDS and am having issues to say the least!

Everytime I run the load packages that I have built into the MDS staging the tables, in MDS_Staging, get cleared down and then repopulated. When the MDS database gets new data it appends it and does not clear down the data that is already in the database and is there fore hold duplicate rows.

Is there a way of truncating the tables in the MDS database before populating again with the new data from the MDS_Staging database so as to not hold duplicate rows?

Thanks everybody!
