Subject Re: [ib-support] Cascading Updates and Deletes?

Hi, Darin!

You have to create a constraint for the detail table and set update and delete cascade.
Example: You have a MASTER table and a DETAIL table.

CREATE TABLE MASTER(
IDMASTER INTEGER NOT NULL,
FIELDA VARCHAR(10),
CONSTRAINT PKMASTER PRIMARY KEY(ID)
);

CREATE TABLE DETAIL(
IDMASTER INTEGER NOT NULL,
IDDETAIL INTEGER NOT NULL,
CONSTRAINT PKDETAIL PRIMARY KEY(IDMASTER, IDDETAIL)
);
ALTER TABLE DETAIL ADD CONSTRAINT FKDETAIL_MASTER FOREIGN KEY(IDMASTER) REFERENCES MASTER(IDMASTER) ON UPDATE CASCADE ON DELETE CASCADE;

I hope I can help you...

Regards,
Giovani.

Does Firebird have Cascade Update Releated Fields and Cascade Delete
Related Fields like MS SQL Server?
