I have 3 tables :
--table A
ID INT
Description VARCHAR(8000)
--table B
ID INT
Description VARCHAR(8000)
--table C
ID INT
ObjectID INT
Type CHAR(1)
ObjectID column in table C contains ID from either table A or table B, for example
ID ObjectID Type
----------- ----------- ----
3 10 A
Result above means the ID with value 10 is coming from table A. I need to put foreign key on ObjectID column that references to ID column in both table A and table B. Is this possible?
