Sql server 执行多个查询的存储过程
存储过程需要5分钟来执行，但若我已经编写了该过程的查询，那个么它将需要4秒。我做了谷歌搜索，发现参数嗅探可以提高程序的性能，所以实现了，现在仍然需要3分钟 我该怎么办 谢谢 阿图尔·亚达夫 这是我的存储过程代码：Sql server 执行多个查询的存储过程,sql-server,Sql Server,存储过程需要5分钟来执行，但若我已经编写了该过程的查询，那个么它将需要4秒。我做了谷歌搜索，发现参数嗅探可以提高程序的性能，所以实现了，现在仍然需要3分钟 我该怎么办 谢谢 阿图尔·亚达夫 这是我的存储过程代码： CREATE PROCEDURE [dbo].[get_all] @para_factor_id int, @para_factor_client_id int, @para_factor_customer_id int, @para_invoic

在存储过程中，您需要首先更改的内容很少 1） 实现索引（如果没有） 2） 不要在join“dbo.fun\u get\u client\u list\u profile\u management”中使用函数 相反，您需要创建一个临时表/表变量，并使用dbo.fun\u get\u client\u list\u profile\u management填充该变量，然后将临时表/表变量与实际查询连接起来。因为当您使用函数而不是表时，会为每一行结果调用函数 3） 同样的事情，你需要做的“投资道具”。用该子查询填充临时表/表变量，然后在实际查询中使用该表 4） 同样的事情也会发生
inv.invoice_status_id IN
(SELECT items
FROM dbo.fun_split_string (@v_invoice_status_id,
','))
OR @v_invoice_status_id = ''
更改这些内容并让我们知道改进情况。可能是缓存中的存储过程计划不好。重新编译它，看看性能是否与查询相当
EXEC sp_recompile N'dbo.get_all';
显示一些代码可能有助于人们回答问题您使用了什么修复程序进行参数嗅探？分配给变量？如果是，请尝试
