C# 如何将日期从SQL Server获取到Oracle 12c？日期正在倒转（向后）

我在将日期从

SQL Server

导入

Oracle

时遇到了一个真正的问题，同时保持了正确的值

SQL Server中的值如下所示：

“1969年4月28日12:00AM”

当我将此值拉入

.NET

日期时间时，它看起来像：

“04/28/1969 12:00AM”

当它被插入Oracle时，它看起来像：“19年4月28日”

---

快速查看Oracle日期看起来是正确的，但是如果我对字符（日期，'MM/DD/YYYY'）进行

操作，我会得到“
04/28/6919
”这对我们来说也是一个问题，无法解决它

虽然我们已经找到了解决办法，但它并不漂亮，但很有效。而且不是一个巨大的时间消费者。
我们将复制关闭，并在成功后更新日期类型列。更新不应该花费太长时间，因为这是一个批量操作

希望这有帮助。干杯

//EF 5.0.0.
private tables entities = new Tables();
private string validFrom; //try with date as well, should work
private int id;
using (OracleBulkCopy bulkCopy = new OracleBulkCopy(applicationContext.GetConnection(CrmContext.ConnectionEnum.CrmDatabase)))
{
            bulkCopy.DestinationTableName = "TABLE";
            bulkCopy.BulkCopyTimeout = 180;
            bulkCopy.WriteToServer(dataTable);
            bulkCopy.Close();
}
//this is a workaroud due to error in Oracle DataAccess Driver
//look at the
entities.Database.ExecuteSqlCommand("UPDATE TABLE SET DATE_FROM = TO_DATE(:p0,'DD.MM.YYYY.') WHERE ID = :p1", validFrom, id);
entities.SaveChanges();

请显示要插入oracle的代码！以及从sql获取该日期的代码。请记住，您始终可以使用以下方法：理想情况下，不要使用字符串表示法。获取作为日期时间，插入作为日期时间…乔恩-这就是我最初所做的。字符串获取是我试图对格式进行更多控制的尝试。我会尽快发布我的代码。。。但真的没什么可看的。这很简单。也许很难做到，但这可能是endian差异吗？有没有简单的方法来确保你只更新刚刚插入的记录？我计划很快尝试一下-谢谢！
