How I use Windows command prompt client and do modifications to my SQL database. If yes, please write the commads I should know for that. If no, please get me the software with which I can do it.
You need to have a Mysql (or similar) server installed on your machine. The best way to do that is with a one-click installer like XAMPP or WAMP which adds an Apache server, MySql, and PHP along with other stuff. One of the 'other stuffs' will be phpMyAdmin, which is a graphical User Interface for your MySql databases.The other method is to use the MySql Command Line Interpreter (CLI) from a DOS prompt, but that is terribly out of date.MySql also has a GUI package, but I have never used it, so do not have an opinion.
