enum ReferentialAction: string

What a foreign key says should happen when the row it points at moves.

Only CASCADE and SET NULL let the statement stand; the rest say the parent was not free to move, so the statement is refused.

Cases§

case NoAction = 'NO ACTION'

case Restrict = 'RESTRICT'

case Cascade = 'CASCADE'

case SetNull = 'SET NULL'

case SetDefault = 'SET DEFAULT'
