[cx-oracletools-users] CopyData.ph without a PK or unique constraint?

Hi,

I'm attempiting to use cx_OracleTool's CopyData.py script to copy data
between two tables on separate Oracle schemas/instances.

I get the error:

No primary or unique constraint found on table.


I don't know much about Oracle, to be honest, but from what I can tell the
tables don't seem to have any PK constraint or anything like that defined.

The merits of this aside, I think it's simply been setup that way for
expediency, and it's unlikely to change anytime nearterm.

Is there any way to get copyData.py to run in this scenario without a PK
constraint?

Cheers,
Victor
