如何使用 php 从 MySql 按姓名和姓氏排序？

Question

我知道我可以这样做 "SELECT * FROM members WHERE isHere = 0 ORDER BY surname" 从我的数据库中获取不在此处的成员并对它们进行排序。但是，如果他们的姓氏相同，我想按名称对他们进行排序。有关如何执行此操作的任何提示？

Answer 1

只需使用多个 ORDER BY 子句即可使用多个排序选项：

SELECT * 
FROM members 
WHERE isHere = 0 
ORDER BY surname ASC,
name ASC

这将首先按姓氏排序，如果两个或多个用户具有相同的姓氏，您可以再按姓名排序。如果你愿意，你也可以添加三分法来按年龄排序。

SELECT * 
FROM members 
WHERE isHere = 0 
ORDER BY surname ASC,
name ASC,
age DESC

Answer 2

您可以对多列进行排序。像这样，

SELECT * 
FROM members 
WHERE isHere = 0 
ORDER BY surname ASC, name ASC;

You can sort on multiple columns, and you can sort different columns in different directions, which means you can sort the result-set by ASC where as name by DESC.

Which is not required in your case but just for info.

默认排序将不区分大小写。如果要对列进行区分大小写的排序，请为列添加 BINARY 关键字。

像这样，

SELECT * 
FROM members 
WHERE isHere = 0 
ORDER BY BINARY surname ASC, name ASC;

Answer 3

如果你想先名后姓，可以这样使用

SELECT * FROM members WHERE isHere = 0 ORDER BY name asc,surname asc;

如果你想先姓再写名字，可以这样使用

SELECT * FROM members WHERE isHere = 0 ORDER BY surname asc,name asc;

根据

排序方式更改asc和desc
