Question

我有一个关于如何根据员工性别找到工资歧视的问题。我有MS Acess 2007，必须使用SQL查询来解决它

请记住，这是在我将3个表连接成一个多表查询之后。在此查询中，每当我想要使用ORDER BY Salary对任何列进行排序时，它会给出一个错误标记：

Syntax error (missing operator) in query expression 'Salary'
WHERE JobClass.JobClassID = Employees.JobClassID 
AND Department.DepartmentID = Employees.DepartmentID'.

我想尝试在查询中对多个列进行排序。

以下是多个查询代码：

SELECT JobClass.JobClassID, JobClassName, Department.DepartmentID, 
       DepartmentName, LastName, FirstName, Title, Sex, Years, Salary
FROM  JobClass, Employees, Department
ORDER BY 'Salary'
WHERE JobClass.JobClassID = Employees.JobClassID AND Department.DepartmentID = Employees.DepartmentID;

Answer 1

按条款排序应该在where子句
之后

试试这个

SELECT JobClass.JobClassID, JobClassName, Department.DepartmentID, 
       DepartmentName, LastName, FirstName, Title, Sex, Years, Salary
FROM  JobClass, Employees, Department
WHERE JobClass.JobClassID = Employees.JobClassID AND Department.DepartmentID = Employees.DepartmentID
ORDER BY Salary

SLECT语法

SELECT [predicate] { * | table.* | [table.]field1 [AS alias1] [, [table.]field2 [AS alias2] [, …]]}     
FROM tableexpression [, …] [IN externaldatabase]     
[WHERE… ]    
[GROUP BY… ]     
[HAVING… ]     
[ORDER BY… ]     
[WITH OWNERACCESS OPTION]

Answer 2

除非Access '07完全忽视标准SQL（我认为不这样做），否则你的SQL语法就会关闭。

不是在ORDER BY WHERE子句之前放置WHERE ，而应该在 {{1}}之后。

如何在多表查询中对多列进行排序？
