SQL Server 2016 Upgrade Advisor Problem

Question

SQL Server 2016 Upgrade Advisor meldet ein Datenbankkompatibilitätsproblem: Regel: konstante Ausdrücke sind in der ORDER BY-Klausel in 90 oder höheren Kompatibilitätsmodi nicht zulässig.

Version90 Regel Titel: Konstante Ausdrücke sind nicht

Empfehlung in der ORDER BY-Klausel in 90 oder höher Kompatibilitätsmodus erlaubt: Bevor Sie die Datenbank-Kompatibilitätsmodus auf 90 oder höher Anweisungen ändern, modifizieren, die in konstanten Ausdrücken verwenden die ORDER BY-Klausel, um einen Spaltennamen oder Spaltenalias oder eine nicht negative Ganzzahl zu verwenden, die die Position des Namens oder Alias ​​in der Auswahlliste darstellt.

Regel-ID: Microsoft.Rules.Data.Upgrade.UR00326

Dies ist der SQL, die den Fehler verursacht, und ich kann nicht herausfinden, wie die Sortierung nach Anweisung ändern, um die Upgrade-Berater zu befriedigen ???

     SUM(qs.total_physical_reads) AS total_physical_reads,

    FROM sys.dm_exec_cached_plans cp 
    CROSS APPLY sys.dm_exec_sql_text(cp.plan_handle) st 
    INNER JOIN GetQueryStats qs ON cp.plan_handle = qs.plan_handle 
    INNER JOIN sys.procedures p ON st.objectid = p.object_id 
    WHERE p.type IN ('P', 'PC') 
    GROUP BY st.dbid, st.objectid, st.text 
    ORDER BY 
    CASE @order 
     WHEN 'name' THEN OBJECT_NAME(st.objectid) 
     WHEN 'size' THEN SUM(cp.size_in_bytes) 
     WHEN 'read' THEN SUM(qs.total_logical_reads) 
     WHEN 'write' THEN SUM(qs.total_logical_writes) 
    ELSE SUM(cp.usecounts) 
END DESC; 
END; 

Ich versuchte, die ORDER BY basierend auf dem Vorschlag zu ändern.

ORDER BY CASE WHEN 'name' @order = THEN OBJECT_NAME (st.objectid, st.dbid) WHEN @order = 'size' THEN SUM (cp.size_in_bytes) WHEN @order = 'lesen' THEN SUM (qs.total_logical_reads) WENN @order = 'schreiben' THEN SUM (qs.total_logical_writes) SONST SUM (cp.usecounts) END DESC;

Aber der SQL Server 2016 Upgrade Advisor meldet immer noch das gleiche Problem.

Sie können keine Variable mehr in der Order By-Klausel verwenden.
