What is SQL? Why do students study SQL?

SQL (Sequential Query Language) is a programming language that is designed to manage a relational database management system (RDBMS). It is the popular query language used to create and manage databases with ease. The mobile and web apps will use SQL to store data safely. You can use SQL to insert, search, update and delete the records from the database. SQL can be used in different operations, which include optimizing as well as managing databases. You can use this to access data that is stored in the RDBMS systems. Using this you can also describe the data. It helps you to store data in the database and change that data anytime using SQL commands.

You can also set permissions to the table, procedures and views. SQL allows you to communicate with the database and perform various tasks, and functions and query the data. With SQL, you can create a table, add data to the table, drop the table, modify the data in the table and set permission to the user who can and cannot access the data.
 

Different types of SQL commands

There are five different types of SQL commands available:

DDL (Data Definition Language) - DDL will change the structure of the database table such as you can create a table, deleting a table and alert the table. Commands of DDL will save permanent changes to the database. Various commands that are used in DDL include create, alter, drop and truncate.

Data manipulation language (DML) - DML is used to modify the database. It will be responsible for the changes made to the database. Commands in DML are not auto-committed therefore the changes are not saved to the database. Various commands available in this type of SQL include insert, update and delete.

Data control language (DCL) - DCL commands allow you to grant and take away the permissions that are given to the user. Various commands available in DCL are granted and revoked.

Transaction control language (TCL) - TCL commands will use the commands such as Insert, delete and update. The operations done are committed to the database automatically. Therefore, you cannot use them for creating and dropping the tables. Commands that you can use are commit, rollback and save point.

Data query language - DQL is used to fetch the data from the database. The only command that you can use in DQL is select.
