OnDeleteAction enum

ON DELETE policy for foreign-key columns. Maps directly to SQLite's ON DELETE CASCADE / SET NULL / RESTRICT / NO ACTION clauses (and to EF Core's OnDelete enum, for parity).

Values

cascade → const OnDeleteAction

Cascade: when the parent row is deleted, the dependent rows are also deleted (recursively).

setNull → const OnDeleteAction

Set null: when the parent row is deleted, the FK column on the dependent rows is set to NULL. The column MUST be nullable.

restrict → const OnDeleteAction

Restrict: the DB rejects the DELETE of the parent row if any dependent row references it.

noAction → const OnDeleteAction

No action (the default): no ON DELETE clause is emitted. The DB uses its own default (which is NO ACTION in SQLite).
