You haven't said what the error was, but a good place to start would be to
get the syntax and spelling correct.

ALTER TABLE TABLE2
ADD CONSTRAINT cons_name FOREIGN KEY (FKEY1) REFERENCES TABLE1(PKEY1)

Note that "REFERENCES" has four Es. Also, if the FK references the PK in
the other table then including the name of the PK column is optional. It
is mandatory where you are referencing a UNIQUE key that is not the PK.

If you're still getting an error then, come back here and tell us what the
message is.
