DELIMITER

I'm trying out some procedures I found at http://artfulsoftware.com/mysqlbook/sampler/mysqled1ch20.html and I'm having difficulties to run them from within HeidiSQL because the DELIMITER keyword triggers a syntax error.

Is it because it's a specific command from the mysql command line tool and not part of MySQL Server's SQL language? Is there a workaround to run scripts that mix different delimiters?

What do you actually try to run? I have no problems using the DELIMITER command here:

delimiter go
select 1

Note that there must NOT be a semicolon after DELIMITER <something>.

I was trying Listing 7. It's weird, the error comes and go if I remove other lines. In particular, adding a blank line between DELIMITER go and CREATE PROCEDURE makes the error go away:

DROP PROCEDURE IF EXISTS famsubtree;
DELIMITER go
CREATE PROCEDURE famsubtree( root INT )
BEGIN
DROP TABLE IF EXISTS famsubtree;
CREATE TABLE famsubtree
SELECT childID, parentID, 0 AS level
FROM familytree
WHERE parentID = root;
ALTER TABLE famsubtree ADD PRIMARY KEY(childID,parentID);
REPEAT
INSERT IGNORE INTO famsubtree
SELECT f.childID, f.parentID, s.level+1
FROM familytree AS f
JOIN famsubtree AS s ON f.parentID = s.childID;
UNTIL Row_Count() = 0 END REPEAT;
END ;
go
DELIMITER ;

I copied the code from the web site using the clipboard. Can it be a mixed line-ending issue?

Think that's fixed now. Looked like the detected end offset of the DELIMITER command was just one char too far to the left. Wonder why I didn't see that while I was testing that before.

Well, there's a lot of stuff to test I guess. I hadn't noticed it either. Thanks for the quick response.

BTW, I've not been able to test it; r3383 starts crashing as soon as I start it :-?

Oh sorry, that AV should be fixed in r3384 now.

Testing should be easy:

DELIMITER foo
SELECT 1;
SELECT 2;
DELIMITER ;

... plus some variations with spaces after delimiter clause.

Now it works like a charm. Thank you!
