我们有一个用于报告构建的Web Api服务。此服务使用MS SQL 2008数据库作为数据源。数据库在只读模式下作为镜像工作。 服务和数据库托管在单个本地网络的不同计算机上。MSSQL存储过程 - 超时过期
有名为TicketSaleByAggregator数据库，用于选择报表数据的存储过程。有时程序会引发以下异常：
System.Data.SqlClient.SqlException (0x80131904): Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out
然后，直到我们重新编译:: ALTER PROCEDURE [DBO] [TicketSaleByAggregator]的过程，一次又一次地抛出此异常。 命令ALTER程序后，程序运行非常好，即使在大数据集，但约10-15小时后再次错误抛出：超时时间已
过程参数：
DECLARE @PeriodFrom DATETIME = '2016-12-30 00:00:00'
DECLARE @PeriodTo DATETIME = '2016-12-30 23:59:59'
DECLARE @Dealers Identities
DECLARE @Branches Identities
DECLARE @SaleChannels Identities
DECLARE @Carriers Identities
INSERT INTO @Dealers (Id) VALUES(10068)
INSERT INTO @Branches(Id) VALUES(1),(2),(3)
INSERT INTO @SaleChannels(Id)VALUES (7)
exec TicketSaleByAggregator @PeriodFrom, @PeriodTo, @Dealers, @Branches, @SaleChannels, @Carriers
如果我们调用程序在本地SQL Management Studio中（在那里举办的计算机上），然后执行15秒 如果我们调用其中的Web API服务托管，在SQL Management Studio中的机器上的程序，然后执行用于15- 16秒 。结果数据中包含82540个记录

嗯，我觉得这个问题是不是在你的店PROC ..但也许在你的C＃代码...因为如果你从哪里是你的WebAPI在同一台服务器调用它在你的SQL枭雄..我不认为概率是在数据库端 –
在C＃端我们使用的是Dapper.SqlMapper.Query方法。据我所知，这种方法使用标准的ADO.NET适配器，它可以映射到dataSet中的对象。我试着在没有Dapper的情况下执行这个查询。谢谢。 – Max
你可以发布的C＃代码？ –
