Hi All,

I have two tables :

1. TableA
    PurchaseOrderNo
    ItemNo
    Qty_A
    Unit_B

2. TableB
    PurchaseOrderNo
    ItemNo_A
    ItemNo_B
    Qty_B
    Unit_b
    ......

How could I set foreign key TableB to TableA for PurchaseOrderNo and ItemNo_A ?

Thank you.

Hi Jogos,

ALTER TABLE TDPOJUALBRGCUSTOMER2012 ADD CONSTRAINT FK_TDPOJUALBRGCUSTOMER2012_Nomor_OA, BarangCode  FOREIGN KEY(Nomor_OA, BarangCode) REFERENCES TDPOJUAL2012(Nomor_OA, BarangCode)

What's wrong with my code ?

TDPOJUALBRGCUSTOMER2012_Nomor_OA, BarangCode.

Should be used what code ?

Thank you.

I also try below :

ALTER TABLE TDPOJUALBRGCUSTOMER2012 ADD CONSTRAINT FK_TDPOJUAL2012_TDPOJUALBRGCUSTOMER2012  FOREIGN KEY(Nomor_OA, BarangCode) REFERENCES TDPOJUAL2012(Nomor_OA, BarangCode)

Exception :

There are no primary or candidate keys in the referenced table 'TDPOJUAL2012' that match the referencing column list in the foreign key 'FK_TDPOJUAL2012_TDPOJUALBRGCUSTOMER2012'. Could not create constraint. See previous errors.

Thank you.
