MySQL Stored Procedure CREATE Error - mysql

Question

I have about 2 years of mySQL under my belt but am diving into stored procedures for the first time to create an internal analytic tool for my site. I am usually good at tracking down SQL errors but this one is eluding me.
The error I get is this :
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 '' at line 3
This is the code I execute to receive this error:
CREATE PROCEDURE STORE_ANALYTICS (IN chain VARCHAR(300))
BEGIN
UPDATE _analytics_clicks
SET chainCount = (chainCount + 1)
WHERE visitChain = chain;
IF SELECT ROW_COUNT() = 0 THEN
INSERT INTO _analytics_clicks (visitChain, chainCount)
VALUES (chain, 1);
END IF;
END|
It is worth noting that before I execute this, I executed
DELIMITER |
The structure of the table I am trying to alter is this:
chainID int(11) auto_increment
visitChain varchar(300)
chainCount int(11)
When I execute line 3 by itself, replacing visitChain=chain with visitChain='0' (0 is a test chain i enetered), the command runs fine and chainCount is incremented.
Any ideas on why I am getting this error/the stored procedure is not being created?
Thanks,
Matt
EDIT :
Included delimiter in SQL command:
DELIMITER |
CREATE PROCEDURE STORE_ANALYTICS (IN chain VARCHAR(300))
BEGIN
UPDATE _analytics_clicks SET chainCount = (chainCount+1) WHERE visitChain=chain;
IF ROW_COUNT() = 0 THEN
INSERT INTO _analytics_clicks (visitChain, chainCount) VALUES (chain, 1);
END IF;
END|
DELIMITER ;
Gave me this error:
Fatal error: Maximum execution time of 300 seconds exceeded in C:\wamp\apps\phpmyadmin3.2.0.1\libraries\import\sql.php on line 119

Answer 1

You can do
IF ROW_COUNT() = 0 THEN
rather than IF SELECT ROW_COUNT() = 0 THEN. No need for the SELECT.

Answer 2

I suspect that your delimiter is not being set properly.
I usually include the delimiter set/unset statements with my SQL source, that way "it just runs" - it's good practice that every SQL file can run stand-alone eg:
delimiter ~
create procedure ...
end;~
delimiter ;
Try changing your delimiter to something less deadly than a pipe char - try my tilda ~ char, which never gives me any trouble. I've seen $$ used often as well.
