Deleting Datawindow Columns

I am using a data store that has 13 columns with data in them. I want to destroy five of them. I know that there is a PB command to do this:
dw_object.Modify("Destroy column colname")
I cannot get this syntax to work. The return code is good for the modify statement but when I do a column count after the 5 modify statement there are still 13 columns; there should only be 8. Why won't it work?

This is because you are only destroying the visual representation of the data. The underlying result set is still the same as when the datawindow was generated.

The only way to achieve this is to rebuild the datawindow at runtime. Take a look at the syntax from SQL command.
