Question

我正在通过C＃进行批量上传。

这不是一段复杂的代码，但是虽然代码运行成功，但是当我对目标表运行查询时，我在数据库端没有看到任何内容。

表是 [awsbillingdetailed_w_res_tags]

public static string BulkUpload(DataTable dt, string tableName, string connectionString)
     {
          string code = "";

//just resizing datatable so that it makes it smaller for testing. Only 5 rows.
          dt = ReduceDataTableSize(dt, 5);

          dt.TableName = tableName;
          string constr = connectionString;
          try
          {
               using (SqlConnection connection = new SqlConnection(constr))
               {
                    connection.Open();

                        bulkCopy.ColumnMappings.Add("ProductName", "productname");
                        bulkCopy.ColumnMappings.Add("RateId", "rateid");

                         //write the data in the "dataTable"
                         bulkCopy.WriteToServer(dt);

                         code = "Data Processed Successfully";
                    }
               }
               return code;
          }



          catch (Exception ex)
          {
              code = "Error while processing file";
              System.Diagnostics.Debug.Write("EXCEPTION BulkUpload: " + ex.ToString());
          }

          return code;
     }

我还进行了双重检查以确保现在没有双引号或任何空白字段。

我没有错误，但实际上没有任何内容进入数据库。有什么想法吗？试图调试这几个小时但是看不到任何问题。阅读大量的论坛，但没有引导我。非常感谢您的帮助。

提前致谢。

好的，刚才意识到我没有完成/提交交易。有趣的是我们需要编写代码，请求帮助然后我们突然得到它。

基本上缺少......

trans.Commit();

批量上传后。谢谢，道歉浪费你的时间：）

C＃中的SQL Server批量上传没有错误但没有插入数据
