为此，您可以使用MAX()。语法如下-

select MAX(yourColumnName) AS anyAliasName from yourTableName;

让我们创建一个表-

mysql> create table demo44
−> (
−> employee_id int not null auto_increment primary key,
−> employee_name varchar(20),
−> employee_salary int
−> )
−> ;

借助insert命令将一些记录插入表中-

mysql> insert into demo44(employee_name,employee_salary) values('John',3000);

mysql> insert into demo44(employee_name,employee_salary) values('David',4500);

mysql> insert into demo44(employee_name,employee_salary) values('Bob',3500);

mysql> insert into demo44(employee_name,employee_salary) values('Carol',5500);

mysql> insert into demo44(employee_name,employee_salary) values('Mike',4900);

使用select语句显示表中的记录-

mysql> select *from demo44;

这将产生以下输出-

+-------------+---------------+-----------------+
| employee_id | employee_name | employee_salary |
+-------------+---------------+-----------------+
| 1           | John          | 3000            |
| 2           | David         | 4500            |
| 3           | Bob           | 3500            |
| 4           | Carol         | 5500            |
| 5           | Mike          | 4900            |
+-------------+---------------+-----------------+
5 rows in set (0.00 sec)

以下是选择最高薪水的查询-

mysql> select MAX(employee_salary) AS Highest_Salary from demo44;

这将产生以下输出-

+----------------+
| Highest_Salary |
+----------------+
|           5500 |
+----------------+
1 row in set (0.00 sec)
