在列MYSQL中分割逗号分隔的值 [英] Split Comma separated Values in Column MYSQL

问题描述

这是我的结果集

    id  cpumanufacturer cpuseries
200014  Intel           Core i7,Core i7 Extreme Edition

200015  Intel           Core i7 Extreme Edition,Core i7

200259  Intel           Core i7 Extreme Edition,Core i7

我想将CPU系列拆分为多行 例如对于第一行"输出应该是

I want to split cpu series to spanned across multiple rows like for First Row output should be

200014 | Intel | Core i7
200014 | Intel | Core i7 Extreme Edition

推荐答案

有一篇博客文章描述了一个存储过程，该存储过程将从此修改表:

There is a blog post that describes a stored procedure that will modify your table from this:

id     cpumanufacturer cpuseries

200014 Intel Core      i7,Core i7 Extreme Edition
200015 Intel Core      i7 Extreme Edition,Core i7
200259 Intel Core      i7 Extreme Edition,Core i7

对此:

id     cpumanufacturer cpuseries

200014 Intel           Core i7
200014 Intel           Core i7 Extreme Edition    
200015 Intel           Core i7 Extreme Edition
200015 Intel           Core i7
200259 Intel           Core i7 Extreme Edition
200259 Intel           Core i7

请记住，这将修改表，而不是查询结果.

Keep in mind that this will modify the table, not your query results.
