订购日期记录并在MySQL中获取第二条有序记录

要进行排序，请使用ORDERBY并仅获取第二个有序记录，并使用MySQLLIMIT并设置偏移量。让我们首先创建一个-

mysql> create table DemoTable1417
   -> (
   -> CustomerId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> CustomerName varchar(20),
   -> ShippingDate date
   -> );

使用insert在表中插入一些记录-

mysql> insert into DemoTable1417(CustomerName,ShippingDate) values('Chris','2019-01-21');
mysql> insert into DemoTable1417(CustomerName,ShippingDate) values('David','2018-12-01');
mysql> insert into DemoTable1417(CustomerName,ShippingDate) values('Carol','2019-09-28');
mysql> insert into DemoTable1417(CustomerName,ShippingDate) values('Sam','2019-08-29');

使用选择显示表中的所有记录-

mysql> select * from DemoTable1417;

这将产生以下输出-

+------------+--------------+--------------+
| CustomerId | CustomerName | ShippingDate |
+------------+--------------+--------------+
|          1 | Chris        | 2019-01-21   |
|          2 | David        | 2018-12-01   |
|          3 | Carol        | 2019-09-28   |
|          4 | Sam          | 2019-08-29   |
+------------+--------------+--------------+
4 rows in set (0.00 sec)

这是获取第二个有序记录的查询-

mysql> select CustomerName,ShippingDate from DemoTable1417 order by CustomerId limit 2,1;

这将产生以下输出-

+--------------+--------------+
| CustomerName | ShippingDate |
+--------------+--------------+
| Carol        | 2019-09-28   |
+--------------+--------------+
1 row in set (0.00 sec)
