Table Constraint to reject record on insert

sharpeApr 26 2013 — edited Apr 26 2013

Is it possible to create a table constraint that would reject records not meeting a specific constraint condition?

I need to reject records being inserted to my Induction_Info table where the bundle does not exist in my Bundle table, but on only when Induction_Info.Project_Code = 'TEST'. Is this possible?

I've attempted this:

ALTER TABLE EXFC.INDUCTION_INFO ADD 
CONSTRAINT chk_induction_info$bundle
 CHECK (bundle in(select bundle from bundle)) ENABLE
 VALIDATE

But when I attempt to compile I get the message:

ORA-02251: subquery not allowed here

I don't even know if what I'm attempting is possible. Can you help? I'd certainly appreciate any help. Thanks.
