Re: Referential Constraint

CREATE TABLE ROB/DCHILD
(DCHILDKY CHAR ( 1) NOT NULL,
MYKEY INT NOT NULL WITH DEFAULT,
SOMEDATA CHAR ( 30) NOT NULL WITH DEFAULT,
PRIMARY KEY (DCHILDKY),
FOREIGN KEY (MYKEY) REFERENCES ROB/DMASTER
(MYKEY) ON DELETE NO ACTION ON UPDATE NO ACTION,
CHECK (SOMEDATA >='A' and SOMEDATA <='Z' ))

Worked fine.
