Interview Question: What are Magic Tables in SQLServer

Magic tables are internal tables called ‘inserted’ and ‘deleted’ which are created and managed by SQL server.

‘Inserted‘ table holds the values that have been recently inserted.

‘Inserted‘ table also holds the updated values from a update operation on a table.

‘Deleted‘ table holds the values that have been recently deleted.
‘Deleted‘ table also holds the previous values from a update operation on a table.

These virtual tables are usually used with triggers to retrieve the inserted, deleted or updated rows.

Upload files using AJAX in ASP.Net MVC

This approach will work on almost all browsers but, you can't upload multiple files, and file information have to send separately. In this method file is send directly in XMLHttpRequest, and file information is send along with HTTP Headers.
js FILE

1. window.onload = function () {
2.     document.getElementById('uploader').onsubmit = function () {
3.         var fileInput = document.getElementById('fileInput');
4.         var xhr = new XMLHttpRequest();
5.         xhr.open('POST', '/Home/Upload');
6.         xhr.setRequestHeader('Content-type', 'multipart/form-data');
7. //Appending file information in Http headers
8.         xhr.setRequestHeader('X-File-Name', fileInput.files[0].name);
9.         xhr.setRequestHeader('X-File-Type', fileInput.files[0].type);
10.         xhr.setRequestHeader('X-File-Size', fileInput.files[0].size);
11. //Sending file in XMLHttpRequest
12.         xhr.send(fileInput.files[0]);
13.         xhr.onreadystatechange = function () {
14.             if (xhr.readyState == 4 && xhr.status == 200) {
15.                 alert(xhr.responseText);
16.             }
17.         }
18.         return false;
19.     }
20. }

Controller:

1. [HttpPost]
2. public JsonResult Upload()
3. {
4.     string fileName = Request.Headers["X-File-Name"];
5.     string fileType = Request.Headers["X-File-Type"];
6.     int fileSize = Convert.ToInt32(Request.Headers["X-File-Size"]);
7. //File's content is available in Request.InputStream property
8. System.IO.Stream fileContent = Request.InputStream;
9. //Creating a FileStream to save file's content
10. System.IO.FileStream fileStream = System.IO.File.Create(Server.MapPath("~/") + fileName);
11. fileContent.Seek(0, System.IO.SeekOrigin.Begin);
12. //Copying file's content to FileStream
13. fileContent.CopyTo(fileStream);
14. fileStream.Dispose();
15. return Json("File uploaded");

Thats all and you are done :)

Posting a complex datatype to server using jQuery

Here I'm going to explain you the steps to POST complex data types to server using jQuery. The we technology whih I'm using here is ASP.NET MVC. You can make appropriate changes in url according to the server which you are using.

Use the following code:

$.ajax({

            type: "POST",

            contentType: "Application/json;charset=utf-8",

            datatType: "json",

            url: $("#_root").val() + "Client/SaveClientSession",

            data: 1,

            success: function (r) {

            },

            error: function (xhr, ajaxOptions, thrownError) {

                alert(xhr.status);

                alert(thrownError);

                alert(xhr.responseText);

            }

        });

type: "POST": Use either GET or POST as per your requirement

contentType: "Application/json;charset=utf-8": This is very important! You have to specify encoding, especially when you are passing complex data types

datatType: "json": Return type of the call

 url: The destination url as per the server technology.

data: pass data to be passed. Use JSON.stringify if using complex types

 success: callback function on successful call

 success: callback function on error
