SQLDATETIME溢出必须是1753年1月1日和12/31/9999从接入之间来为sql

Question

我从一个MS Access数据库获取数据，并在我的控制台应用程序使用此代码将其移动到SQL Server：

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(); 
     Console.WriteLine("Truncated NetWeightMasterDataTable"); 
    cmd.CommandText = "INSERT INTO [dbo].[Net Weight Master Data]

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

我Access表中有，但在我的SQL Server表中的一些空的日期，我让它允许空值，但我仍然得到错误

SQLDATETIME溢出必须是1753年1月1日和12 /间31/9999

我意识到，这个错误也出现在日期不是正确的格式，但我也检查了，这一切看起来不错，所以我还错过了什么？

Answer 1

1. 建议1：如果你想确保每一行是正确的SQL Server日期时间格式，你可以在你的数据表中写一个foreach它从ACCESSDB和检查数据填充后如果它小于1753/1/1 ...如果它是真的，则分配一个有效值（空或GETDATE（））。
2. 建议2：您可以使用System.Data.SqlTypes.SqlDateTime.MinValue属性更新c＃中的数据行。 （看看这里：https://msdn.microsoft.com/en-us/library/system.data.sqltypes.sqldatetime.minvalue(v=vs.110).aspx）

Answer 2

访问的下限低于sql中的下限。
在这里看到：Date Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM OverFlow error SqlBulkCopy
