如何使用group-concat mysql创建json格式?

如何使用group-concat mysql创建json格式?

(我使用MySQL)

范例1:

表格1:

email            |    name  |   phone

-------------------------------------

my1@gmail.com | Ben | 6555333

my2@gmail.com | Tom | 2322452

my2@gmail.com | Dan | 8768768

my1@gmail.com | Joi | 3434356

像语法代码那样的格式:

select email, group-concat(name,phone) as list from table1 

group by email

我需要的输出:

email         |    list

------------------------------------------------

my1@gmail.com | {name:"Ben",phone:"6555333"},{name:"Joi",phone:"3434356"}

my2@gmail.com | {name:"Tom",phone:"2322452"},{name:"Dan",phone:"8768768"}

谢谢

回答:

试试这个查询-

SELECT

email,

GROUP_CONCAT(CONCAT('{name:"', name, '", phone:"',phone,'"}')) list

FROM

table1

GROUP BY

email;

JSON格式结果-

+---------------+-------------------------------------------------------------+

| email | list |

+---------------+-------------------------------------------------------------+

| my1@gmail.com | {name:"Ben", phone:"6555333"},{name:"Joi", phone:"3434356"} |

| my2@gmail.com | {name:"Tom", phone:"2322452"},{name:"Dan", phone:"8768768"} |

+---------------+-------------------------------------------------------------+
