Alter table - foreign key - Error 1064

[kiwibrit]

I have two tables within a database.

The first is 'clicks'

It has four fields:
Name: fil_id
type: int(10)
PRIMARY KEY

Name: customer_id
type: int(4)

Name:location
Type: varchar(100)

Name: uniqid
Type: varchar(15)

The second table is 'downloads'

It has two fields:

Name: customer_id
Type: int(4)
PRIMARY KEY

Name: username
Type: varchar(35)

When I run the following SQL in phpmyadmin

ALTER TABLE clicks ADD FOREIGN KEY (customer_id) REFERENCES downloads(customer_id) SHOW ERRORS

I get an error #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 'SHOW ERRORS' at line 1

I've looked at this one quite intensively. As the tables hold no data I could just drop them and recreate, including the foreign key. But I would like to nail the problem and I just can't figure it. Can you help?

I am running MySQL 5.07 locally on my Windows 7 PC.

ALTER TABLE clicks ADD FOREIGN KEY (customer_id) REFERENCES downloads(customer_id) SHOW ERRORS

Have you used SHOW ERRORS before in this context? I thought it was a separate statement?

Ha! No I hadn't, thank you. SQL ran correctly once I followed up on your link.

I've forgotten how to mark the thread as solved.
