从 Visual Studio 2012 执行时存储过程“旋转”答案

【问题标题】：Stored Procedure "spins" when executed from Visual Studio 2012从 Visual Studio 2012 执行时存储过程“旋转”

【问题描述】：

我已经编写了 3 个存储过程，并且在 SQL Server 中执行时都运行良好。但是，当我在 Visual Studio 2012 中执行它们时，它们只是“旋转”、创建锁等。有什么想法吗？

这是其中之一。另一种是从基于相同 SQL 的内联视图中选择值，而不是插入到 #temp

    @StartDate      As DateTime,
    @EndDate        As DateTime,
    @EmployeeCode   As VarChar(50) = NULL 
AS

   ou.Code AS DEPT_UNIT_CODE,
   CASE
       WHEN ec1.Classification = '1' THEN
           MIN(ec1.TransactionDate)
   END AS CLOCK_IN,
   CASE
       WHEN ec2.Classification = '2' THEN
           MAX(ec2.TransactionDate)

【问题讨论】：

有一些“影响计划的选项”会改变 SQL Query Planner 创建计划以执行查询的方式，这些可能会导致执行完全相同的 SQL 代码的不同客户端之间的主要性能差异。比较 ANSI_NULLS、ANSI_PADDING、ANSI_WARNINGS、ARITHABORT、CONCAT_NULL_YIELDS_NULL 和 QUOTED_IDENTIFIER 的 SSMS 和 Visual Studio 设置。通读 Erland Sommarskog 的优秀文章 Slow in the Application, Fast in SSMS? Understanding Performance Mysteries 了解为什么会发生这种情况。
一个非常基本的存储过程SELECT 1 会导致同样的问题吗？我建议您逐步添加代码，直到找到导致问题的部分。或使用sp_whoisactive 确定导致问题的等待类型。

标签： sql-server visual-studio stored-procedures

【解决方案1】：

它们是不同的执行环境。是的，阅读已经推荐的 Sommarskog 的文章。但我认为这些程序缓慢（并且不一致）的主要原因是UNION 运算符。你应该使用UNION ALL。其次，摆脱这些（nolock）提示。他们不帮助你。如果你真的需要它，你应该使用

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;

在您的程序开始时。也一样。

谢谢先生！我会试一试并发布结果。
