What Is SQL?
SQL stands for the structure query language that is one of the domain-specific languages. This language is very powerful for the database management system. SQL performs several functions in a database system, i.e., insert, update, delete, and create a record in a database system. SQL creates new tables and also creates several procedures in a database system. SQL involves data definition language, data manipulation, data modification, and this data control language.
What Are The Types of SQL?
Below are the five types of widely used SQL queries:
DDL (Data Definition Language) is a programming language that allows you to specify the database structure or schema.
The Data Manipulation Language (DML) allows you to insert, change, and delete data from a database instance. It's in charge of making all kinds of changes to a database's data.
GRANT and REVOKE are commanding in the DCL (Data Control Language) that can be used to grant "rights and permissions."
TCL or transaction control language commands deal with database transactions.
The data is retrieved from the database using Data Query Language (DQL).
