Question

When I import a DUMP into an SQlite3 database I manually have to activate the foreign_keys again afterwards.

PRAGMA foreign_keys = ON;

When creating a dump the dump looks like this:

PRAGMA foreign_keys = OFF;
BEGIN TRANSACTION;
[...]
COMMIT;

When I add the activation command manually it is ignored:

PRAGMA foreign_keys = OFF;
BEGIN TRANSACTION;
[...]
COMMIT;
PRAGMA foreign_keys = ON;

Is there a way to reactivate the foreign_keys automatically when a Dump is imported?

Answer 1

The PRAGMA foreign_keys = ON; does activate foreign keys.
However, this setting is not stored in the database.
You have to execute this pragma for every new connection to the database.
