    How to do it...
    Follow these steps to create a subroutine to store QVD then drop a table:
    Before the load statement for Table1, add the following script:
    Sub StoreAndDrop(vTableName)
    Store [$(vTableName)] into [$(vTableName).qvd];
    Drop Table [$(vTableName)];
    End Sub
    After the Table1 load and before the Table2 load, add the following line of script:
    Call StoreAndDrop('Table1');
    After the Table2 load, add the following line of script:
    Call StoreAndDrop('Table2');
    Reload the script. There should be no data in the document and two QVD files should have been created in the same folder as the QVW file.
