Thread: Detect referential integrity structure

Detect referential integrity structure

From

Hi,

I've a big/complex database (Adempiere - www.adempiere.org ) where I'd
like to delete some rows from some tables (delete a client and its
data from the ERP database).
All tables are in one schema (adempiere).
There are some foreign keys/constraints.
I've following options:

- disable all constraints, doing the delete, enable all constraints.
- find out the "right sequence" and do the delete -s.

Does anyone have such an algorythm, or a method of disabling all the
constraints? We have 8.3.7 right now. The solution will be published
into the Adempiere wiki / contributed to the project as well.

Thanks in advance,
Akos Gabriel

Perhaps another option:

Alter the references to ON DELETE CASCADE as seen here
