如何在 MySQL 中获取表中的倒数第二条记录?
要获得倒数第二条记录,即 MySQL 中的倒数第二条记录,您需要使用子查询。
语法如下
SELECT *FROM (SELECT *FROM yourTableName ORDER BY yourIdColumnName DESC LIMIT 2) anyAliasName ORDER BY yourIdColumnName LIMIT 1;
我们先创建一个表。创建表的查询如下
mysql> create table lastRecordBeforeLastOne - > ( - > Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, - > Name varchar(20) DEFAULT 'John', - > Age int DEFAULT 18 - > ); Query OK, 0 rows affected (0.79 sec)
现在,您可以使用插入命令插入一些记录到表中。
查询如下
mysql> insert into lastRecordBeforeLastOne values(); Query OK, 1 row affected (0.21 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Larry',23); Query OK, 1 row affected (0.19 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Mike',19); Query OK, 1 row affected (0.20 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Sam',24); Query OK, 1 row affected (0.22 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Bob',26); Query OK, 1 row affected (0.13 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('David',22); Query OK, 1 row affected (0.23 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('James',29); Query OK, 1 row affected (0.14 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Carol',21); Query OK, 1 row affected (0.23 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Maxwell',29); Query OK, 1 row affected (0.18 sec) mysql> insert into lastRecordBeforeLastOne(Name,Age) values('Chris',25); Query OK, 1 row affected (0.14 sec)
使用 select 语句显示表中的所有记录。
查询如下
mysql> select *from lastRecordBeforeLastOne;
以下是输出
+----+---------+------+ | Id | Name | Age | +----+---------+------+ | 1 | John | 18 | | 2 | Larry | 23 | | 3 | Mike | 19 | | 4 | Sam | 24 | | 5 | Bob | 26 | | 6 | David | 22 | | 7 | James | 29 | | 8 | Carol | 21 | | 9 | Maxwell | 29 | | 10 | Chris | 25 | +----+---------+------+ 10 rows in set (0.00 sec)
这是获取 MySQL 中第二条最后一条记录的查询
mysql> SELECT *FROM - > (SELECT *FROM lastRecordBeforeLastOne ORDER BY Id DESC LIMIT 2) tbl1 - > ORDER BY Id LIMIT 1;
以下是输出
+----+---------+------+ | Id | Name | Age | +----+---------+------+ | 9 | Maxwell | 29 | +----+---------+------+ 1 row in set (0.00 sec)
