Sql 如何在多任务查询中对多个列进行排序？

我有一个关于如何发现基于员工性别的工资歧视的问题。我有MS Acess 2007，必须使用SQL查询才能找到答案

请记住，这是在我将3个表合并到一个多表查询中之后。在这个查询中，每当我想对任何列进行排序时，例如，

orderbysalary

，它都会给我一个错误标志，告诉我：

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

我想尝试对查询中的多个列进行排序

以下是多表查询代码总计：

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;

除非Access'07完全忽略了标准SQL（我认为不是这样），否则您的SQL语法是关闭的

与其将

ORDER BY

放在

WHERE

子句之前，不如放在

WHERE

之后

ORDERBY子句应位于where子句之后

像这样试试

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]

order by

应位于

where

子句之后，并通过'Salary'从订单中删除'。嗯，SQL.oh，抱歉，where中没有

WHILE

子句。嗯。
