Hi all,
I was trying this:
http://forge.mysql.com/snippets/view.php?id=4
That is supposed to emulate a split() in mysql.
Could anyone make it work ?
I've been trying without luck. I 'm getting strange errors when trying to
create this procedure.

DROP PROCEDURE IF EXISTS split_string
CREATE PROCEDURE split_string (
IN input TEXT,
IN delimiter VARCHAR(10)
)
SQL SECURITY INVOKER
BEGIN
DECLARE cur_position INT DEFAULT 1 ;
DECLARE remainder TEXT;
DECLARE cur_string VARCHAR(1000);
DECLARE delimiter_length TINYINT UNSIGNED;
DROP TEMPORARY TABLE IF EXISTS SplitValues;
CREATE TEMPORARY TABLE SplitValues (
value VARCHAR(1000) NOT NULL PRIMARY KEY
) ENGINE=MEMORY;
SET remainder = input;
SET delimiter_length = CHAR_LENGTH(delimiter);
WHILE CHAR_LENGTH(remainder) > 0 AND cur_position > 0 DO
SET cur_position = INSTR(remainder, delimiter);
IF cur_position = 0 THEN
SET cur_string = remainder;
ELSE
SET cur_string = LEFT(remainder, cur_position - 1);
END IF;
IF TRIM(cur_string) != '' THEN
INSERT INTO SplitValues VALUES (cur_string);
END IF;
SET remainder = SUBSTRING(remainder, cur_position + delimiter_length);
END WHILE;
END
