Question

我有这个存储过程从4个表中提取数据并按4列排序，但我需要一个具有相同结果的视图（当然没有参数）。这可能吗？我知道我不能在视图中使用临时表，任何解决方案？！

ALTER PROC pr_GetChildrenByPersonID
    @pePersonIDs varchar(8000)

    SELECT 
        *,
        RANK() OVER (PARTITION BY pbsPersonID ORDER BY psbPersonSiblingID ASC) AS CustomRank

    FROM 
        PersonSibling
    WHERE 
        pbsSiblingTypeID = 2
        AND pbsPersonID IN (SELECT item 
                            FROM dbo.fn_ParseStrListIdentity(@pePersonIDs, ','))

使用Common Table Expression (CTE)而不是临时表，并使用现在使用临时表的CTE。

像这样：

WITH 
    TempPersonSibling AS (
        -- the select statement that creates the temp table here
        -- without the INTO clause
    )
SELECT
    pePersonID,
    ISNULL((SELECT pbsName FROM TempPersonSibling WHERE pbsSiblingTypeID = 2  AND pbsPersonID = pepersonID AND CustomRank = 1),'') AS ChildrenName1,
    -- ..., rest of the query is similar
FROM
    Person
WHERE
    -- ...

这样您就可以在视图中创建单个查询和包。
