如何在MySQL中按任意关键字排序？
为此，请使用ORDERBYFIELD()ASC。让我们首先创建一个表-
create table DemoTable(Title varchar(100));
使用插入命令在表中插入一些记录-
insert into DemoTable values('Java');
insert into DemoTable values('C');
insert into DemoTable values('Python');
insert into DemoTable values('MongoDB');使用select语句显示表中的所有记录-
select *from DemoTable;
这将产生以下输出-
+---------+ | Title | +---------+ | Java | | C | | Python | | MongoDB | +---------+ 4 rows in set (0.00 sec)
以下是按任意关键字排序的查询-
select *from DemoTable order by FIELD(Title,'MongoDB,C,Python,Java') ASC;
这将产生以下输出-
+---------+ | Title | +---------+ | Java | | C | | Python | | MongoDB | +---------+ 4 rows in set (0.00 sec)
