MySQL实现Split用法

CREATE  PROCEDURE sp_split(in words varchar(2000),in regex varchar(20))
BEGIN
CREATE TEMPORARY TABLE IF NOT EXISTS temp_key_split
(
key_words varchar(20)
);
DELETE FROM temp_key_split;
while(instr(words,regex)0) DO
INSERT temp_key_split(key_words) VALUES (substring(words,1,instr(words,regex)-1));
set words = INSERT(words,1,instr(words,regex),'');
END WHILE;
INSERT temp_key_split(key_words) VALUES (words);
END;

MyBatis中操作存储过程

<select parameterType="pd" statementType="CALLABLE">
call sp_split((
SELECT GROUP_CONCAT(seo_keywords) FROM shopping_goods WHERE seo_keywords LIKE CONCAT(CONCAT('%', #{goods_key}),'%')
), ',');
</select>
