TRUNCATE, like other DDL, cannot be directly used in a PL/SQL program (required execute immediate)

yes, you're using the wrong tool

where are your data coming from?

you probable either need to user exp/imp to move the data (assuming you don't have a live DB LINK connection between the databases -- if you do, then you likely just need to do an INSERT ... SELECT), or, as suggested, use SQL*Loader

(i guess this thread would have been a lot shorter if we asked these questions in the first place!)
