MySQL用逗号连接列

1、表结构:

create table tableName(
  `ID` int(11) NOT NULL AUTO_INCREMENT COMMENT 'ID',
  `name` varchar(20) NOT NULL AUTO_INCREMENT COMMENT 'name',
)

 2、插入例子数据:

insert into tableName values(1, 'one');
insert into tableName values(2, 'two');
insert into tableName values(3, '333');
insert into tableName values(4, 'sisi);

 3、用逗号连接列的sql

select 
  GROUP_CONCAT(name) as names
from tableName

 4、结果:

one,two,333,sisi
