我有一个奇怪的问题，我甚至不确定如何排除故障。我正在使用VS2008和SQL Server 2005（是的，我知道它的2013年： - ））。
我们在Visual Studio中有以下代码，基本上传入一个变量，然后使用存储过程创建一个字符串，然后使用作为参数传递的变量执行SP。
奇怪的是，我们收到错误陈述
从字符串转换日期时间
时转换失败
在大多数情况下，这不是一个不寻常的错误，但在这里它变得有趣。
如果我取destCmd.Commandtext字符串值并将其粘贴到SQL Server并执行，它会快速处理并且没有任何错误。更具讽刺意味的是，存储过程不会返回任何记录（这是正确的）。
回顾一下，一个存储过程，当在SQL Server中运行时正确处理并且不返回任何记录（准确），但是从Visual Studio执行时相同的SP以某种方式发现数据转换错误（即使SP不应该＆＃39） ; t返回任何记录）。这种行为不是我之前见过的，也不知道如何解决问题。
我意识到我可以通过重新执行我的SP来解决这个问题，但是由于SP在SQL Server中工作，我想知道为什么我在SP时遇到错误的根本原因从VS2008处理。
存储过程的副本添加在下面的c＃代码下面。
for (int ii = 0; ii < tmpCountryList.Length; ii++)
{
SuppLog.WriteLog(_logGuid, "Calibrating premium", "Start");
info1 = "Calibrating premium";
destCmd.CommandText = "exec proc_s6_to_pcw_calibration " + tmpCountryList[ii];
destCmd.ExecuteNonQuery();
SuppLog.WriteLog(_logGuid, "Calibrating premium", "Finish");
}
存储过程：
