How can I create a foreign key which references an entire composite key?

Question

I have two tables one has a three column composite key. The other needs to reference this composite key.

What is the syntax for creating a foreign key which references multiple columns.

I tried googleing, but I couldn't find it.

Answer 1

FOREIGN KEY (col1, col2, col3) REFERENCES ParentTable (colA, colB, colC)

Look under "<table_constraint>" in the online docs for Microsoft SQL Server CREATE TABLE.
