Legal StudiesSELECT 无限使用 LAST ENTRY 在 MySQL 中
为此，您可以使用子查询。让我们在使用 insert 命令在表中首次创建记录 −
mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.54 sec)
使用 insert 命令在表中添加一些记录 −
mysql> insert into DemoTable(Name) values('John Smith');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable(Name) values('David Miller');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(Name) values('Chris Brown');
Query OK, 1 row affected (0.22 sec)使用 select 语句从表中显示所有记录 −
mysql> select *from DemoTable;
输出
+----+--------------+ | Id | Name | +----+--------------+ | 1 | John Smith | | 2 | David Miller | | 3 | Chris Brown | +----+--------------+ 3 rows in set (0.00 sec)
以下是无需在 MySQL 中使用 LIMIT 即可获取最后一条记录的查询 −
mysql> select *from DemoTable -> where Id=(select max(Id) from DemoTable);
输出
+----+-------------+ | Id | Name | +----+-------------+ | 3 | Chris Brown | +----+-------------+ 1 row in set (0.00 sec)
