如何使用 group-concat mysql 创建 json 格式?
(我使用 MySQL)
示例 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
就像没有给我格式的语法代码:
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
