Execute Data Loader IDL from a Query tool script

I have created a data-loader script and saved as an idl-file.
Can I start this script with a command from a scrript in the Query tool?

No, there is currently no way to directly execute an IDL-file of Invantive Data Loader in the Invantive Query Tool or Invantive Data Hub.

As an alternative, a framework like:

bulk insert into <TARGETTABLE>
select ...
from   <SOURCETABLE>

can be used.

There are currently no plans to add this functionality, since most users directly code their data loads in the Query Tool using synchronize, create or replace table and/or bulk insert.
