Here is my query thus far:
SELECT [Id], [HotelName], [StarRating], [Description], [CheckinDate], [CheckoutDate], [Price], [ImageUrl]
FROM
(
SELECT TOP (6) [Id], [HotelName], [StarRating], [Description], [CheckinDate], [CheckoutDate], [Price], [ImageUrl], RANK() OVER(PARTITION BY [StarRating] ORDER BY [StarRating]) AS Num
FROM [dbo].[Hotel]
WHERE [CityId] = @CityId
AND CheckinDate > GETDATE()
AND [StarRating] IN (3, 4, 5)
) X
WHERE Num <= 2
What I want is to get 2 rows for each star rating: 2 of rating 3, 2 of rating 4 and 2 of rating 5. How can I do this? I have come up with the above after doing some research online already, but I am obviously not fully understanding hwo to implement it, because it is not working... I am getting 6 rows of star rating 3
Use ROW_NUMBER function - for example,
WITH X
AS
(
SELECT
[Id], [HotelName], [StarRating], [Description],
[CheckinDate], [CheckoutDate], [Price], [ImageUrl],
ROW_NUMBER() OVER(PARTITION BY [StarRating] ORDER BY [Id]) AS Num
FROM
[dbo].[Hotel]
WHERE
[CityId] = @CityId
AND CheckinDate > GETDATE()
AND [StarRating] IN (3, 4, 5)
)
SELECT
[Id], [HotelName], [StarRating], [Description],
[CheckinDate], [CheckoutDate], [Price], [ImageUrl]
FROM
X
WHERE
Num <= 2
