带有INNER JOIN的SQL ROW_NUMBER

Question

我需要在以下Query中使用ROW_NUMBER()来返回结果的第5到10行.谁能告诉我我需要做什么？我一直试图无济于事.如果有人可以提供帮助,我会非常感激.

SELECT * 
FROM   villa_data 
       INNER JOIN villa_prices 
         ON villa_prices.starRating = villa_data.starRating 
WHERE  villa_data.capacity >= 3 
       AND villa_data.bedrooms >= 1 
       AND villa_prices.period = 'lowSeason' 
ORDER  BY villa_prices.price, 
          villa_data.bedrooms, 
          villa_data.capacity 

Answer 1

您需要将其粘贴在表格表达式中以进行过滤ROW_NUMBER.您将无法使用,*因为它会抱怨starRating多次出现的列名称,因此需要明确列出所需的列.无论如何,这是更好的做法.

WITH CTE AS
(
SELECT /*TODO: List column names*/
       ROW_NUMBER() 
          OVER (ORDER BY villa_prices.price, 
                         villa_data.bedrooms, 
                         villa_data.capacity) AS RN
FROM   villa_data 
       INNER JOIN villa_prices 
         ON villa_prices.starRating = villa_data.starRating 
WHERE  villa_data.capacity >= 3 
       AND villa_data.bedrooms >= 1 
       AND villa_prices.period = 'lowSeason' 

)
SELECT /*TODO: List column names*/
FROM CTE
WHERE RN BETWEEN 5 AND 10
ORDER BY RN
