You can't have it both ways. Since all TRUNCATE TABLE does is to deallocate
the extents, it cannot check whether you violate any constraints. It can
only check whether there is a possibility for this to happen. I.e., there
are referencing foreign keys.

There are two options:
1) Drop constraints, truncate tables, load data, reapply constraints.
2) Do not drop constraints, and use DELETE to remove the data.
