Question

I keep getting the following error when trying to make one column in a table refference another column in another table.

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FOREIGN KEY (campaignid) REFERENCES campaigns(id)' at line 1

In this case I want to have the column “campaignid” in table “pages” refference (= to) column “id” in the table “campaigns.

ALTER TABLE pages FOREIGN KEY (campaignid) REFERENCES campaigns(id)

Can anyone see where I am going wrong?

Thanks in advance!

Your missing the ADD keyword i suppose (MySQL docu):

ALTER TABLE pages ADD FOREIGN KEY (campaignid) REFERENCES campaigns(id);
