How to create procedure in MySQL database?

                 In this post, we will see how to create procedure in MySQL database. 
             
What is the need of procedure?

1. By creating procedure, we can run multiple SQL queries in a single call. 

2. Another advantage is that procedure is stored and can be called at any time. No need to write same SQL queries again and again. 

For Demonstration, watch following video:

Java MySQL Insert Example using Prepared Statement

                      In this post, we will see Java MySQL Insert Example using Prepared Statement.

                In previous post https://www.comrevo.com/2017/07/jdbc-code-to-insert-data-into-mysql-database.html, we have seen how to insert records (rows) into MySQL database. Here, we will see how to use PreparedStatement. 

For details, watch following video:

Watch on YouTube: https://www.youtube.com/watch?v=S6mJpp5Dg7c

What is the need of Prepared Statement?:
               Sometimes we need to implement same query multiple times e.g. insert query to add multiple records into table. In this situation, only data get changed while the syntax for SQL query remains same. Here, unnecessarily we compile the same query multiple times. To avoid this, we have to use PreparedStatement.

What is PreparedStatement?
               PreparedStatement is an Interface. Stament interface is extended in PreparedStament interface.

               Here sdldb is the database name. User name is sdl and password is sdl123. This program is for inserting records (rows) into MySQL database table student.
