MYSQL如何在連接表中排序

Question

我有這個SQL正在工作，但它不是按照我想要的順序排列。它完全忽略了命令的順序。

這是SQL

SELECT Sales.saleId, Sales.tax, Sales.subtotal, Sales.total, Sales.created as createdTemp, Users.firstName, Users.lastName 
      FROM Sales 
      JOIN Users 
      ON Sales.userId = Users.userId 
      JOIN Companies 
      ON Companies.companyId = 1 
      ORDER BY Sales.saleId DESC 

Answer 1

試試這個：

SELECT * FROM 
(
    SELECT Sales.saleId, Sales.tax, Sales.subtotal, 
     Sales.total, Sales.created as createdTemp, 
     Users.firstName, Users.lastName 
      FROM Sales 
      JOIN Users 
      ON Sales.userId = Users.userId 
      JOIN Companies 
      ON Companies.companyId = 1 
) AS s 
ORDER BY s.saleId DESC;
