Question

首先我要说的是，我对存储过程没有太多帮助，所以我对此的看法可能完全没错，但我想我会来这里试试找在将整个事情吹起来并重新开始之前，解决我当前的问题。

我有一个存储过程，只是运行了一堆我已经放在一起的其他查询。它由一堆Insert，Update和Delete查询组成，当我运行此存储过程时，需要2个小时才能完成。

当我单独运行每个查询时，总共需要大约45分钟。

显然，单独运行它们并将它们作为存储过程运行之间存在很大的时间差异，但是能够运行单个存储过程要方便得多。

我做过一些研究，最常见的答案是减速是由于＆＃34;参数嗅探＆＃34;。我对参数嗅探答案的问题是我没有在我的存储过程中内置任何参数。正如我之前提到的，我构建了一堆查询，并将它们简单地粘贴到存储过程中。这可能不是最好的方法，但当时对我来说是有道理的。

我的问题是，存储过程是否运行较慢，因为我没有参数或因其他原因导致转速较慢？此外，有没有办法在我现有的配置下加快速度？

以下是我的存储过程与第一对查询的示例。

ALTER PROCEDURE [dbo].[LDS_Step_2]

--******* Text Import 2 Append ********

    INSERT INTO [dbo].[Text_Import_2]([Foundation_Account_Number], [Foundation_Account_Name], [Billing_Account_Number], [Billing_Account_Name], [Wireless_Number], [Market_Cycle_End_Date], [Item], [Day], [Date], [Time], [To_From], [Type], [KB_Msg_Min], [Rate_Pd], [Rate_Code], [Feature], [In_Out], [Intl_Tax], [Roaming_indicator], [Total_Charge])
        Select
            [Foundation Account Number], [Foundation Account Name],
            [Billing Account Number], [Billing Account Name],

存储过程比SQL Server中的查询慢
