First of all, questions about SQL 2005 are best asked in the SQL 2005
newsgroups, as these are monitored by the SQL Server deverlopers. Access
info here: http://go.microsoft.com/fwlink/?linkid=31765
As for your question, the syntax is as in this example:
ALTER TABLE tbl ADD CONSTRAINT fk_myforeignley (col1, col2)
REFERENCES othertbl (col1, col2)
Or were you using the table designer? I recommend that you learn the
syntax to create table from SQL statements. In the long run that will
make you more effective and productive, than clicking around in the
table designer. Also, there are several *serious* bugs in the table
designer when it comes to modify existing tables, so the less you use
it, the better.
(If you are dead set on it, I believe that if you right-click there
are foreign keys in the context menu.)
