SqlDateTime 溢出必须介于 1/1/1753 和 12/31/9999 之间，来自对 sql 的访问

Question

我正在从 MS Access 数据库中获取数据并将其移动到 SQL 服务器，在我的控制台应用程序中使用以下代码：

if (getvalue == "plantname")
{
        Console.WriteLine("NetWeightMasterData-Plant Started");
        var dw = new System.Data.DataTable();
        string accdbConnStriok = ConfigurationManager.ConnectionStrings["NetWeightIok"].ToString();
        using (var accdbConn = new OdbcConnection(accdbConnStriok))
        {
       using (var da = new OdbcDataAdapter("SELECT [Unit UPC Base Item],
    [Production Line],[Preset Number],[Package Type],[Weight Factor],
    [Piece],[Pcs Per Unit],[Upper Limit Unit],[Upper Limit Factor],
    [Label Wt (g)],[Tare Wt (g)],[Constant Tare Wt (g)],
    [Tare Variation Factor (g)],[Pkg Length (mm)],[Film Product Code],
    [Film Width (mm)],[Forming Tube (mm)],[Type of Jaws],[Last Updated],
    [Comments] FROM [Net Weight Master Data]", accdbConn))
           {
             da.Fill(dw);

           }
        }
    Console.WriteLine("DataTable filled from NetWeight db NetWeightMasterData-Iola- Row count: {0}", dw.Rows.Count, DateTime.Now.ToString());
    string sqlConnStriok = ConfigurationManager.ConnectionStrings["sqlconiok"].ToString();
     using (var sqlConn = new SqlConnection(sqlConnStriok))
       {
         sqlConn.Open();
         using (var cmd = new SqlCommand())
       {
          cmd.Connection = sqlConn;
         cmd.CommandText = "CREATE TABLE #NetWeightMasterData ([Unit UPC Base Item] [nvarchar](50) NOT NULL,[Production Line] [nvarchar](50) NOT NULL,

               cmd.ExecuteNonQuery();
                  }
        using (SqlTransaction tran = sqlConn.BeginTransaction(System.Data.IsolationLevel.ReadCommitted))
           {
            try
           {
            using (var sbc = new SqlBulkCopy(sqlConn, SqlBulkCopyOptions.Default, tran))
         {
        sbc.BatchSize = 100;
        sbc.NotifyAfter = 100;
        sbc.BulkCopyTimeout = 100;
        sbc.DestinationTableName = "#NetWeightMasterData";                                       Console.WriteLine(DateTime.Now.ToString());
        sbc.WriteToServer(dw);
        Console.WriteLine("After Datatable", DateTime.Now.ToString());
         }
         }
         catch (Exception ex)
         {
         Console.WriteLine(ex.Message.ToString());
         }
         Console.WriteLine(DateTime.Now.ToString());
          using (var cmd = new SqlCommand())
           {
          cmd.Connection = sqlConn;
           cmd.Transaction = tran;
           cmd.CommandText = "SELECT COUNT(*) AS n FROM #NetWeightMasterData";
           Console.WriteLine("SqlBulkCopy complete. Temp table row count: {0}", cmd.ExecuteScalar());
         cmd.CommandText = "TRUNCATE TABLE [dbo].[Net Weight Master Data]";
        cmd.ExecuteNonQuery();

     string answer = Console.ReadLine();
        if (answer == "y")
        {
       LoadNetWeightMasterData();
        }
       else
        {
        LoadNetWeightTracking();
        }
       }
       }
       }

我的访问 table 中有一些空日期，但在我的 SQL 服务器中 table 我让它允许空值，但我仍然收到错误

SqlDateTime Overflow must be between 1/1/1753 and 12/31/9999

我意识到当日期格式不正确时也会出现此错误，但我也检查了一下，一切看起来都不错，所以我还缺少什么？

Answer 1

访问权限下限低于sql。
看这里：

Answer 2

建议1：如果你想确保每一行都是正确的SQL服务器日期时间格式，你可以在数据表中填充来自AccessDb的数据后在数据表中写一个foreach并检查它是否更小然后 1753/1/1... 如果为真，则分配一个有效值（null 或 GETDATE()）。
建议 2：您可以使用属性 System.Data.SqlTypes.SqlDateTime.MinValue 在 c# 中更新数据行。（在这里查看：https://msdn.microsoft.com/en-us/library/system.data.sqltypes.sqldatetime.minvalue(v=vs.110).aspx）

SqlDateTime 溢出必须介于 1/1/1753 和 12/31/9999 之间，来自对 sql 的访问
