I have been given a mySQL database to restructure into an OpenCart installation.
I've pulled most of the data across but in the old site "product categories" have been all put in a single column
|228|243|228|239|228|
|88|
|88|243|
products_to_categories
One option that I recommend is to use common_schema and specifically functions get_num_tokens()
and split_token()
, this will help.
Here a simple example of the use that you can adapt for your solution:
/* CODE FOR DEMONSTRATION PURPOSES */
/* Need to install common_schema - code.google.com/p/common-schema/ */
/* Procedure structure for procedure `explode1` */
/*!50003 DROP PROCEDURE IF EXISTS `explode1` */;
DELIMITER $$
CREATE PROCEDURE `explode1`(str varchar(65500), delim VARCHAR(255))
BEGIN
DECLARE _iteration, _num_tokens INT UNSIGNED DEFAULT 0;
DROP TEMPORARY TABLE IF EXISTS `temp_explode`;
CREATE TEMPORARY TABLE `temp_explode` (`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `word` VARCHAR(200), PRIMARY KEY (`id`));
SET _num_tokens := (SELECT `common_schema`.`get_num_tokens`(str, delim));
WHILE _iteration < _num_tokens DO
SET _iteration := _iteration + 1;
INSERT INTO `temp_explode` (`word`) SELECT `common_schema`.`split_token`(str, delim, _iteration);
END WHILE;
SELECT `id`, `word` FROM `temp_explode`;
DROP TEMPORARY TABLE IF EXISTS `temp_explode`;
END $$
DELIMITER ;
/* TEST */
CALL `explode1`('Lorem Ipsum is simply dummy text of the printing and typesetting', CHAR(32));
