Chris,

The column in the parent table needs to be the PK or be unique. Should be no problem.

We have a designer that is adding a FK on two columns from one table to another. These two columns are not in the parent table's primary key.

So we are kind of scratching our heads wondering if you can, from a proper design point of view, create such a FK? It appears that if you update one of the two columns in the child table then you would need to create a new record in the parent table.

Thoughts??
