Question

我有一个在SQL Server Express 2008计算机上运行的脚本。

/* BUD501T */
declare @ErrMsg      nvarchar(4000)
declare @ErrLine    nvarchar(100)
declare @currentFY nvarchar(1000)

set @ErrMsg = ''
set @ErrLine = ''
set @programName = 'BUDPROD - GL_Exp.sql'
select @currentFY = value from Budgets.dbo.Config where [key] = 'current_fy';


/* GL EXP */

/*Log*/
EXEC [Budgets].dbo.Log_SP @program = @programName ,@message = 'Starting';

这很长但很简单。它清除表格并插入更新的信息，然后对我们使用的数据进行一些修复。它在主插入中插入大约200,000行数据。

我的问题是，有时候这个东西会在大约6分钟内运行，有时会在大约20分钟内运行，有时它会在大约2小时内运行。我不能把它钉住，我让它运行大约一个星期（它计划每天早上5:15运行）。现在它确实击中了一些链接的服务器，但我有其他工作点击相同的链接服务器并且它们是一致的，不像这样。

所以我的问题是发生了什么？内存不足（毕竟这是Express版本）？我可以判断链接服务器是否正在减慢速度？查询有问题吗？

谢谢，奇

Answer 1

您可以激活SET STATISTICS TIME ON以及SET STATISTICS IO ON。

STATISTICS TIME将为您提供有关哪个SQL语句需要多长时间的信息。这可以让您确定是否存在导致问题的特定语句或整体性能是否缓慢。

STATISTICS IO将告诉您执行了多少IO访问。如果您在此处看到较大的变化，则可能意味着SQL Server缓存无法正常运行或者不时使用次优执行计划。

此外，您可以在后台运行SQL Server Performance Counters。之后，您可以检查慢速和快速性能与特定性能计数器值之间是否存在相关性。这允许您验证这是否是内存问题。

您需要查看执行计划和统计信息。这篇文章可能有助于您入门 - Execution Plan Basics
