Sql server SQL查询的运行速度比存储过程快
我最近在生产服务器上修改了一个存储过程，它开始运行得很差，但当我独立运行查询时，它运行得很好。时间上的差异很大，即将5秒与10分钟进行比较是令人震惊的 我读了这篇文章，并尝试用所有可能的解决方案来解决我的问题，但存储过程仍然不起作用，因为它在计时上有相同的差异 有人能告诉我应该更改什么以使我的存储过程至少与查询一样快吗？我对SQL Server的这种行为感到有点惊讶 好计划Sql server SQL查询的运行速度比存储过程快,sql-server,tsql,sql-server-2008,Sql Server,Tsql,Sql Server 2008,我最近在生产服务器上修改了一个存储过程，它开始运行得很差，但当我独立运行查询时，它运行得很好。时间上的差异很大，即将5秒与10分钟进行比较是令人震惊的 我读了这篇文章，并尝试用所有可能的解决方案来解决我的问题，但存储过程仍然不起作用，因为它在计时上有相同的差异 有人能告诉我应该更改什么以使我的存储过程至少与查询一样快吗？我对SQL Server的这种行为感到有点惊讶 好计划 |--Clustered Index Seek(OBJECT:([IndusLynk].[dbo].[Assessme
