CASCADE
Remarks
If you specify
CASCADE
when creating a Foreign Key, Pervasive PSQL uses the
DELETE CASCADE
rule. When a user deletes a row in the parent table, Pervasive PSQL deletes the corresponding rows in the dependent table.
Use caution with delete cascade. Pervasive PSQL allows a circular delete cascade on a table that references itself. See examples in
Delete Cascade
in
Advanced Operations Guide
.
