我在visual studio 2010中有一个程序，我有一个生成水晶报告报告的功能。该查询在我的一个存储过程中提供，以从我的数据库中检索信息。
单击生成报告时出现的问题，返回结果需要很长时间。我想知道是否有人建议如何通过优化存储过程中的查询来更快地提高执行时间？
以下是存储过程的片段：
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[M_RPT_DailyIssuedVoucher]') AND type in (N'P', N'PC'))
BEGIN
EXEC dbo.sp_executesql @statement = N'ALTER PROCEDURE [dbo].[M_RPT_DailyIssuedVoucher]

FROM IssuedVoucher with (nolock)
WHERE
(@EventCode = '''' OR (EventCode = @EventCode))

AND (@Status = '''' OR (Status = @Status))
AND(@DtFrom IS NULL OR IssueDate >= @DtFrom )
AND (@DtTo IS NULL OR IssueDate <= @DtTo)
ORDER BY SerialNo, EventCode
以下是对issvoucher的创建表的查询：

根据我的经验，WHERE运算符可能是问题所在。我有一个类似的问题，不是报告引擎，而是从数据库访问信息。 Imo，IS NULL正在降低性能。我可能错了，因为我不是数据库的破解者。 我解决了我的问题，而不是排除IS NULL语句。收集完数据后，我在C＃中生成了一个包含此类语句的新集合。

首先，为什么每次改变proc都是我无法理解的？
你可以简单地从你的代码中调用proc，并在动态Sql中只选择select onward。
你可以用这种方式修改你的内部选择查询。如果你的表是索引，那么它可以利用索引。
