如何按条件分组？

Question

我必须做一组项目。

例如：

Item 1:
name: test1
date: 2018-01-01
column1: column1
column2: column2
column1: column3
column2: column4

Item 2:
name: test1
date: 2018-01-03
column1: column5
column2: column6
column1: column7
column2: column8

Item 3:
name: test2
date: 2018-01-01
column1: column9
column2: column10
column1: column11
column2: column12

Item 4:
name: test3
date: 2018-01-05
column1: column13
column2: column14
column1: column15
column2: column16

我想做一个sql，获取项目，按日期分组，但每个名称只有一个，我的例子：

name: test1 
date: 2018-01-03
column1: column5
column2: column6
column1: column7
column2: column8

name: test2
date: 2018-01-01
column1: column9
column2: column10
column1: column11
column2: column12

name: test3
date: 2018-01-05
column1: column13
column2: column14
column1: column15
column2: column16

你有一个想法如何实现这一点？问候
