MySQL DELIMITER not working - mysql

Question

I've tried a tutorial from this site, where a sample table gets inserted along with some testing data in a stored procedure. But unfortunately an error message is thrown, saying there's something wrong with the DELIMITER. The whole script is:
CREATE TABLE filler (
id INT NOT NULL PRIMARY KEY AUTO_INCREMENT
) ENGINE=Memory;
CREATE TABLE t_hierarchy (
id INT NOT NULL PRIMARY KEY,
parent INT NOT NULL,
lft INT NOT NULL,
rgt INT NOT NULL,
sets LineString NOT NULL,
data VARCHAR(100) NOT NULL,
stuffing VARCHAR(100) NOT NULL
) ENGINE=MyISAM;
DELIMITER $$
CREATE PROCEDURE prc_filler(cnt INT)
BEGIN
DECLARE _cnt INT;
SET _cnt = 1;
WHILE _cnt <= cnt DO
INSERT
INTO filler
SELECT _cnt;
SET _cnt = _cnt + 1;
END WHILE;
END;
CREATE PROCEDURE prc_hierarchy(width INT)
main:BEGIN
DECLARE last INT;
DECLARE level INT;
SET last = 0;
SET level = 0;
WHILE width >= 1 DO
INSERT
INTO t_hierarchy
SELECT COALESCE(h.id, 0) * 5 + f.id,
COALESCE(h.id, 0),
COALESCE(h.lft, 0) + 1 + (f.id - 1) * width,
COALESCE(h.lft, 0) + f.id * width,
LineString(
Point(-1, COALESCE(h.lft, 0) + 1 + (f.id - 1) * width),
Point(1, COALESCE(h.lft, 0) + f.id * width)
),
CONCAT('Value ', COALESCE(h.id, 0) * 5 + f.id),
RPAD('', 100, '*')
FROM filler f
LEFT JOIN
t_hierarchy h
ON h.id >= last;
SET width = width / 5;
SET last = last + POWER(5, level);
SET level = level + 1;
END WHILE;
END
$$
DELIMITER ;
START TRANSACTION;
CALL prc_filler(5);
CALL prc_hierarchy(585937);
COMMIT;
CREATE INDEX ix_hierarchy_parent ON t_hierarchy (parent);
CREATE INDEX ix_hierarchy_lft ON t_hierarchy (lft);
CREATE INDEX ix_hierarchy_rgt ON t_hierarchy (rgt);
CREATE SPATIAL INDEX sx_hierarchy_sets ON t_hierarchy (sets);
Executing this on a MySQL 5.0.51a-24+lenny2 server gives me the following error message:
[Err] 1310 - End-label $$ without match
Does anyone know why this occurs and how to fix it?

Answer 1

$$ should be after every created procedure.
CREATE PROCEDURE prc_filler(cnt INT)
BEGIN
DECLARE _cnt INT;
SET _cnt = 1;
WHILE _cnt <= cnt DO
INSERT
INTO filler
SELECT _cnt;
SET _cnt = _cnt + 1;
END WHILE;
END$$ -- here's your problem
That's why it is called delimiter - it separates SQL commands. You have ';' inside procedures and '$$' outside of them.

Answer 2

I have seen some MySQL clients that don't support the DELIMITER keyword and throw an error... I believe it is your case... You should try to use a different client, maybe the CLI tool bundled with MySQL (if you can...)?
