hi,
I think its not possible to do......
Try to do the following one...
For this U should add another column in TableC.
Key_IDa is foreign key and references to Table A PK.
Key_IDb is foreign key and references to Table B PK.
Why dont you check with the Wizard options availed from SSMS.
For relationships btwn tables ,Creating Foreign Keys........
🙂
Thanks!
