The first and the main thing about this application is its name. SQL FYI is basically SQL For Your Information (FYI). As its name suggests its an informative application.
This application consists of information regarding the basic syntax of SQL commands and information about those commands along with the examples.
I started making the app for myself but now its done so this reference guide can be usefull to others as well and this will help people to know about SQL. Nothing bad in spreading information worldwide. Feel free to send your inputs to me.
