Pagination and Sorting via SQL

PAGINATION is the concept of splitting a larger data set into several smaller sets before transferring and displaying to the user. What this means is that instead of sending large bulks of information across the wire, that would otherwise consume a lot of resources (network traffic, memory/cache etc), we split the large bulks into smaller manageable chunks and only handle as much data that is needed.

Pagination can be seen everywhere; from Blogs and Forums, to News sites. All these use some form of pagination or another. Without pagination Forums would be showing thousands of topics at once instead of showing 20 topics per page; Blogs would be showing hundreds of blog posts per page instead of 10 posts per page. News sites… well.. they would take a rather long time to load if they displayed all of articles at once!

There are several forms of Pagination available; and no doubt you would have come across one or more already:

  • The first is what I refer to as Preemptive Loading
  • The second is On Demand Loading

In this article I will explain each of these in detail. I will explain the short comings of Preemptive Loading, and the benefits of On Demand Loading; and also explain how On Demand Loading can be achieved via SQL Server…

How to enable SQL FileStream Types


FILE
uploads in the traditional sense is all about uploading data files to the Server and keeping it there for downloading later on. If you are like me and have coded Web Applications with File uploading capabilities – then it’s most likely you have configured your Web application to accept and store these uploaded files in an ”upload’ folder on the server; while the relative path (or perhaps the full-path) to the file is stored as a field in the database.

This works fine… there are no major issues with this method at all.

In this article I will explain some alternative solutions to this method, and show how you can enable the use of SQL Server FileStreams in your applications…
