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"} |
+---------------+-------------------------------------------------------------+
