Question

我尝试创建一个存储过程，该过程采用索引从哪里开始，最大行显示和位置。它们会返回HouseID的列表和位置，但我还希望它包含另一个名为dbo.House的表格中的“房子名称”，该表格HouseId将其链接到那个地点。我该如何添加第二张表。

谢谢，

CREATE PROCEDURE dbo.basicHouseSearch 
    @StartIndex int,
    @MaxRows int,
    @HouseLocation NVarChar(50)
AS
BEGIN
    SET NOCOUNT ON;

    Select 
       Location.HouseID, CityTown 
    FROM
       (SELECT 
           ROW_NUMBER() OVER (ORDER by Location.HouseID) as RowNumber,
           Location.HouseID,
           CityTown
        FROM dbo.Location) Location
    WHERE 
        RowNumber >= @StartIndex 
        AND ROWNUMBER < (@StartIndex + @MaxRows) 
END
GO

Answer 1

我重写了你的代码所以它使用了CTE（我认为它更清晰）：

;WITH CTE AS
(
    SELECT  RowNumber = ROW_NUMBER() OVER (ORDER by L.HouseID),
            L.HouseID,
            L.CityTown,
            H.Name [Name of the house]
    FROM dbo.Location L
    LEFT JOIN dbo.House H
        ON L.HouseID = H.HouseID
)
SELECT *
FROM CTE
WHERE RowNumber >= @StartIndex 
AND RowNumber < (@StartIndex + @MaxRows)

Answer 2

我重写了你的代码，所以它使用OFFSET / FETCH（我觉得它更清晰）：

SELECT  L.HouseID,
        L.CityTown,
        H.Name [Name of the house]
FROM dbo.Location L
LEFT JOIN dbo.House H
    ON L.HouseID = H.HouseID
ORDER BY L.HouseID
OFFSET @StartIndex ROWS FETCH NEXT @MaxRows ONLY

（需要Sql Server 2012或更高版本）

SQL Server存储过程与ROW_NUMBER
