环绕到第一个值，并在单个查询中实现MySQL ORDER BY ASC和DESC

2024-04-24 01:15:03 430

让我们首先创建一个表-

mysql> create table DemoTable
   -> (
   -> Value int
   -> );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values(20);
mysql> insert into DemoTable values(40);
mysql> insert into DemoTable values(30);
mysql> insert into DemoTable values(10);
mysql> insert into DemoTable values(90);
mysql> insert into DemoTable values(70);
mysql> insert into DemoTable values(80);
mysql> insert into DemoTable values(9);
mysql> insert into DemoTable values(8);

使用select语句显示表中的所有记录-

mysql> select *from DemoTable ;

这将产生以下输出-

+-------+
| Value |
+-------+
|    20 |
|    40 |
|    30 |
|    10 |
|    90 |
|    70 |
|    80 |
|     9 |
|     8 |
+-------+
9 rows in set (0.00 sec)

这是将“环绕”到第一个值并在单个查询中实现ORDERBYASC和DESC的查询-

mysql> select *from DemoTable
   -> order by Value > 10 desc,Value asc;

这将产生以下输出-

+-------+
| Value |
+-------+
|    20 |
|    30 |
|    40 |
|    70 |
|    80 |
|    90 |
|     8 |
|     9 |
|    10 |
+-------+
9 rows in set (0.00 sec)
