SQL Server Bulk Upload in C# no error but not inserting data

Question

I am doing a bulk upload through C#.

It is not a complicated piece of code, but struggling as although the code runs successfully I am not seeing anything on the Database end when I run a query against the destination table.

The table is [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();
                    //CreatingTranscationsothatitcanrollbackifgotanyerrorwhileuploading
                    SqlTransaction trans = connection.BeginTransaction();
                    //Start bulkCopy
                    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection,
                    SqlBulkCopyOptions.TableLock |
                    SqlBulkCopyOptions.FireTriggers,
                    trans))
                    {
                         //Fix up default values
                         if(dt.Rows.Count > 0)
                         {
                                for (int i = 0; i < dt.Rows.Count; i++)

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

                         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;
     }

I have also double checked to ensure there were no double quotes or any blank fields for now.

I get no errors, but nothing actually gets into the DB. Any ideas why? Lost a few hours trying to debug this but cannot see any issues. Read plenty of forums but lead me no where. Your help is much appreciated.

Thanks in advance.

Answer 1

Ok, just realised that I did not finished/committed the transaction. Funny how we need to write the code , cry for help and then we just suddenly get it.

Essentially missing...

trans.Commit();

after the bulk upload. Thanks and apologies for wasting ur time :)
