Question

我有一个名为EMPLOYEE的表，有17个不同的列。一列称为Salary，它是显示所有员工薪水的列。我想计算最高工资，我知道这不是正确的答案。该列中的最高薪水是131250，随着该报表，它继续拉高该值。不知道为什么它没有计算所有员工。

SELECT MAX（CAST（Salary as MONEY））AS Highest_Salary FROM Employee

结果= 131250

首先数据类型是varchar，然后我将其更改为money而下一个int仍然不好。可能是什么问题？

Answer 1

尝试使用

SELECT MAX（CAST（薪水为DECIMAL（12,2）））AS Highest_Salary FROM Employee

Answer 2

您可能打算放SELECT MAX(CAST(Salary as MONEY)) AS Highest_Salary FROM Employee WHERE Salary = X但是老实说找到最大值，您不希望涉及WHERE条款，所以只需删除= 131250

Answer 3

您是否尝试删除此部分＆＃39; = 131250＆＃39;并尝试查看输出??

Answer 4

SELECT MAX（转换（金钱，薪水））AS Highest_Salary FROM Employee

Answer 5

你想找到最高工资或平均工资吗？

最高工资

SELECT MAX(CAST(Salary as MONEY)) AS Highest_Salary FROM Employee

平均工资

SELECT AVG(CAST(Salary as MONEY)) AS Highest_Salary FROM Employee

Answer 6

如果您想要每位员工的最高工资，可以使用GROUP BY

SELECT CAST(MAX(Salary) as MONEY) AS Highest_Salary
FROM Employee
GROUP BY EmployeeID

如果您希望获得可以使用应用程序的平均值，或者运行此其他查询。

SELECT CAST(AVERAGE(Highest_Salary) as MONEY) as avg_salary
FROM (
  SELECT CAST(MAX(Salary) as MONEY) AS Highest_Salary
  FROM Employee
  GROUP BY EmployeeID
) high_salaries

计算所有员工的最高工资
