title: Azure Table Storage: 404 Error during execution of Insertion
body: <p>I am writing a query to insert 300k rows to a table, i get a 404 File or Directory not found error during the execution of insertion. i am a noob to azure so i may have written some stupid code</p>
  
  <p>I create the DynamicTableEntity objects here :</p>
  
  <pre><code>       Test t = new Test();
         t.CreateTable("table2");
          Dictionary&lt;string, EntityProperty&gt; dic;
          Random random = new Random();
  
          ArrayList part1 = new ArrayList();
          ArrayList part2 = new ArrayList();
          ArrayList part3 = new ArrayList();
          ArrayList part4 = new ArrayList();
          ArrayList part5 = new ArrayList();
          ArrayList part6 = new ArrayList();

          Stopwatch sw = new Stopwatch();
          Guid guid;
          sw.Start();
          for (int i = 0; i &lt; 300000; i++)
          {
  
              dic = new Dictionary&lt;string, EntityProperty&gt;();
  
              dic.Add("count", new EntityProperty(i));
              dic.Add("rand1", new EntityProperty(random.Next()));
              dic.Add("rand2", new EntityProperty(random.Next()));
              dic.Add("rand3", new EntityProperty(random.Next()));
              if(i!=5)
              dic.Add("rand4", new EntityProperty(random.Next()));
              else
                  dic.Add("rand4", new EntityProperty(1234561));
  
  
              if (i % 2 == 0)
  
                  dic.Add("randInt", new EntityProperty(random.Next()));
              else

              dte = new DynamicTableEntity("0" + (i % 3), DateTime.UtcNow.Ticks.ToString() + guid + i);
  
              dte.Properties = dic;
  
              if (i % 6 == 0)
                  part1.Add(dte);
              else if (i % 6 == 1)
                  part2.Add(dte);
              else if(i%6==2)
                  part3.Add(dte);
              else if (i % 6 == 3)
                  part4.Add(dte);
              else if (i % 6 == 4)

              if( (i + 1) % 600 == 0)
              {
  
                  t.Insert("table2", part1, part2, part3, part4, part5, part6);
                  part1.RemoveRange(0,100 );
                  part2.RemoveRange(0, 100);
                  part3.RemoveRange(0, 100);
                  part4.RemoveRange(0, 100);

                  part6.RemoveRange(0, 100);
              }
  
  
  
          }
  </code></pre>
  
  <p>And Here is the insertion execution code :</p>
  
  <pre><code>        CloudTable table = _tableClient.GetTableReference(tableName);
          TableBatchOperation tablebatchoperation;
          int i = 0, j = 0;
          if (created == false)
              table.CreateIfNotExists();
  
          foreach (ArrayList k in l)
          {
              tablebatchoperation = new TableBatchOperation();
  
              foreach (DynamicTableEntity dte in k)
              {
                  tablebatchoperation.Insert(dte);
              }
              table.ExecuteBatch(tablebatchoperation);
          }
  </code></pre>
  
  <p>I appreciate your help</p>
