我认为这是你需要的(存储过程)：

Mysql split column string into rows

DELIMITER $$

DROP PROCEDURE IF EXISTS explode_table $$

CREATE PROCEDURE explode_table(bound VARCHAR(255))

BEGIN

DECLARE id INT DEFAULT 0;

DECLARE value TEXT;

DECLARE occurance INT DEFAULT 0;

DECLARE i INT DEFAULT 0;

DECLARE splitted_value INT;

DECLARE done INT DEFAULT 0;

DECLARE cur1 CURSOR FOR SELECT table1.id, table1.value

FROM table1

WHERE table1.value != '';

DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

DROP TEMPORARY TABLE IF EXISTS table2;

CREATE TEMPORARY TABLE table2(

`id` INT NOT NULL,

`value` VARCHAR(255) NOT NULL

) ENGINE=Memory;

OPEN cur1;

read_loop: LOOP

FETCH cur1 INTO id, value;

IF done THEN

LEAVE read_loop;

END IF;

SET occurance = (SELECT LENGTH(value)

- LENGTH(REPLACE(value, bound, ''))

+1);

SET i=1;

WHILE i <= occurance DO

SET splitted_value =

(SELECT REPLACE(SUBSTRING(SUBSTRING_INDEX(value, bound, i),

LENGTH(SUBSTRING_INDEX(value, bound, i - 1)) + 1), ',', ''));

INSERT INTO table2 VALUES (id, splitted_value);

SET i = i + 1;

END WHILE;

END LOOP;

SELECT * FROM table2;

CLOSE cur1;

END; $$
