我的程序在复杂查询中间歇性失败。

错误如下：

System.Data.SqlClient.SqlException：无法从链接服务器“LinkedServer”的OLE DB提供程序“MSDASQL”中获取行。

查询如下所示：

                                                     dbo.SFGET_UniqueTaskID([CLIENT-CODE],Replace([JOB-NO], 'M0', ''), 0, [TRADE-CODE]) AS HMSUniqueTaskID,

                                                  ON ibsTasks.[PLACE-REF] = prop.UserCode

我一直在使用SQL Server Management Studio手动测试它。它偶尔会失败但主要工作正常。

我不知道如何调试我无法随意重现的错误。

有什么建议吗？

我自己并不精通SqlClients和Progress，但是：Progress Knowledgebase可能会给你一个解决方案！

例如，

This entry描述了一个类似的错误，即使提到的版本可能比您使用的版本旧？（在询问OpenEdge时总是发布版本 - 那里有很多旧的安装，而且Progress在过去几年中发展了很多）。

诚然，最好使用Google搜索知识库：

搜索实例：site:knowledgebase.progress.com MSDASQL，您将获得48 results。
