I am trying to setup some contraints in Oracle 8i and for some reason
I am getting told by Oracle that ID is not a primary key and it errors
out on that. However in the attached SQL, I set the column ID as a PK
up top along with PQUESTIONID. Where might my error lie in this SQL?
It errors out before it gets to the very last constraint, so erroring
out on the second to last constraint.
--Remove QDEPNDENCY PK
ALTER TABLE QDEPENDENCY DROP CONSTRAINT PK_QDEPENDENCY;
--Add new QDEPENCY PK
ALTER TABLE QDEPENDENCY ADD CONSTRAINT PK_QDEPENDENCY PRIMARY KEY (ID,
PQUESTIONID);
--Add QDEPENDLISTS PK
ALTER TABLE QDEPENDLISTS ADD CONSTRAINT PK_QDEPENDLISTS PRIMARY KEY
(QDEPENDID, LISTITEMID);
-- Add constraint for deletion of Dependents
ALTER TABLE COILSAFE.QDEPENDLISTS
ADD CONSTRAINT REM_QDEPENDLISTS
FOREIGN KEY (QDEPENDID)
REFERENCES COILSAFE.QDEPENDENCY (ID)
ON DELETE CASCADE;
-- Add constraint for deletion of Questions
ALTER TABLE COILSAFE.QDEPENDENCY
ADD CONSTRAINT REM_QDEPENDENCY
FOREIGN KEY (PQUESTIONID)
REFERENCES COILSAFE.FRMQUESTIONS (ID)
ON DELETE CASCADE;
