hi, I think foreign key doesn't work if the referecing column is not a Primary key. Is there any work around for this ? I need to check the column value in a X table, before inserting data into a Y table; but the column in X tabe is not a primary key.
foreign key Integrity constraint that requires each value in a column or set of columns to match a value in a related table's UNIQUE or PRIMARY KEY. Trigger before insert or update... perform a query (for existence) on the other table to see if the value exists is one way.
