【转】mysql用sql实现split函数

a.id , a.NAME , substring_index(substring_index(a.shareholder, ‘,‘, b.help_topic_id + 1), ‘,‘, - 1) AS shareholder FROM company a INNER JOIN mysql.help_topic b ON b.help_topic_id < (length(a.shareholder) - length(REPLACE(a.shareholder, ‘,‘, ‘‘)) + 1)

基本表建立语句

CREATE TABLE `company` (
`id` int(20) DEFAULT NULL,
`name` varchar(100) DEFAULT NULL,
`shareholder` varchar(100) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `company` VALUES (‘1‘, ‘阿里巴巴‘, ‘马云‘);
INSERT INTO `company` VALUES (‘2‘, ‘淘宝‘, ‘马云,孙正义‘);
