我正在尝试使我们的应用程序发送的查询更有效。我稍微修改了 SSMS 中的查询，它将在大约 1 秒内执行。

查询 A

SELECT  O.Code AS 'Code', O.[Action] AS 'Action',
    SUM(OpenResponseWithin) AS 'OpenResponseWithin',
    CONVERT(VARCHAR,convert(decimal(10,2),(((SUM(OpenResponseWithin))*100))/convert(decimal(10,2),(SUM(OpenResponseWithin)+SUM(OpenResponseAfter))))) + '%' AS 'OpenResponseWithinPercentage',
    SUM(OpenResponseAfter) AS 'OpenResponseAfter',
    CONVERT(VARCHAR,convert(decimal(10,2),(((SUM(OpenResponseAfter))*100))/convert(decimal(10,2),(SUM(OpenResponseWithin)+SUM(OpenResponseAfter))))) + '%' AS 'OpenResponseAfterPercentage',
    (SUM(OpenResponseWithin)+SUM(OpenResponseAfter)) AS 'OpenTotal',
    SUM(CloseResponseWithin) AS 'CloseResponseWithin',
    CONVERT(VARCHAR,convert(decimal(10,2),(((SUM(CloseResponseWithin))*100))/convert(decimal(10,2),(SUM(OpenResponseWithin)+SUM(OpenResponseAfter))))) + '%' AS 'CloseResponseWithinPercentage',
    SUM(CloseResponseAfter) AS 'CloseResponseAfter',
    CONVERT(VARCHAR,convert(decimal(10,2),(((SUM(CloseResponseAfter))*100))/convert(decimal(10,2),(SUM(OpenResponseWithin)+SUM(OpenResponseAfter))))) + '%' AS 'CloseResponseAfterPercentage',
    SUM(CloseNever) AS 'CloseNever',
    CONVERT(VARCHAR,convert(decimal(10,2),(((SUM(CloseNever))*100))/convert(decimal(10,2),(SUM(OpenResponseWithin)+SUM(OpenResponseAfter))))) + '%' AS 'CloseNeverPercentage'
FROM Custom_OpenCodeMRC O
WHERE O.ActionDate BETWEEN '10/5/2017' AND '12/4/2017'
      AND
      O.Code IN ('BERZ20','BERZ21','BERZ24','BERZ50','FTHZ63','YOR56','YOR57')
GROUP BY O.Code,O.[Action]
ORDER BY O.Code,O.[Action]

如果我按照应用程序通过参数传入的方式保留查询，则执行至少需要 20 秒。
