To learn the basics of SQL Server, you must have an understanding of how an SQL Server query engine executes an SQL query. T-SQL involves both logical and physical query processing. Physical query processing is about how a database engine processes a query. Logical query processing is a conceptual flow, an order of the clauses knowing how SQL Server evaluates these clauses while executing a query.

YouTube has always been a great place for exploring music for free. With millions of user-uploaded videos and with the help of the smart suggestion feature, you may never run out of songs to play.

You probably cannot imagine Android without the Play Store and its apps. Apps bring color to Android’s operating system and are the reason why the Android ecosystem is thriving. From time to time, you may download an app, use it for a while, and then forget that it exists. Look at your Android device, and see how many apps you have. Now, try to remember the last time you used some of them. You may be shocked once you realize that you only used some of your apps one time, but they have been sitting on your phone for months. These apps take up space. If you have an unused app and you want to delete it, this tutorial will show you how to uninstall Android apps.

The best way to handle unused apps is to uninstall them. This tutorial describes how to uninstall iPhone apps quickly and easily.
I love two things in life: tech and casinos. When I think of those two things, I think of the Consumer Electronic Show (CES).

In order to give you the best CES had to offer, I stayed focused and avoided the casinos (but I played an online Arabic casino at Casino Arbi). I wish I could cover everything at CES 2017, but let’s start with the best of the best.

With more than 600 million users, Instagram has a large, fast-growing community. Besides personal photos, Instagram users also share shots of products or videos that you may find useful for future reference. In the past, whenever you came across Instagram posts that you wanted to save, you could either like them or save them to another app. The first solution is not ideal for privacy as your likes are visible to your followers while the latter is time-consuming and inconvenient. Fortunately, Instagram has noticed this problem and provided a feature for users to save Instagram posts privately to their accounts with just a tap. Continue reading to find out how to use this feature.
By default, any application can access an iPhone’s cellular data. If you want to browse the internet using a browser app (e.g., Safari) on your iPhone, you would only need to turn on either your Wi-Fi or your cellular data. It is that simple. You just need to have an internet connection, and any app can access the internet, using either a Wi-Fi connection or your cellular data. Depending on the type and the purpose of the apps on your iPhone, some apps are able to run in the background, continually using the internet connection of your device. For those who use cellular data without unlimited data plans, this can cause higher data charges. If you want to continue using your network data and, at the same time, disable specific apps from accessing the internet through your cellular data connection, then you are on the right page. This tutorial shows how you can restrict specific apps from using cellular data on iPhone.
