Wie kann ich eine gespeicherte Prozedur in eine Ansicht transformieren?

Question

Ich habe diese gespeicherte Prozedur, die Daten aus 4 Tabellen und rangiert sie um 4 Spalten, aber ich brauche eine Ansicht mit dem gleichen Ergebnis (natürlich ohne Parameter). Ist das möglich? Ich weiß, dass ich keine temporäre Tabelle im Blick haben kann, keine Lösung ?!

ALTER PROC pr_GetChildrenByPersonID

Answer 1

ein Common Table Expression (CTE) statt einer temporären Tabelle, die Verwendung und den CTE verwenden, wo Sie die temporäre Tabelle jetzt verwenden.

Wie so:

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 
    -- ... 

diese Weise können Sie eine einzelne Abfrage erstellen und Paket, das aus Ihrer Sicht.
