SQL is among the most well-known database languages. SQL is easy to learn in its syntax. In addition, it is a database that can be utilized across platforms and other database systems.
How do I get the data?
The term database refers to a set of data that is easy to organize, view and gain access to. It is a repository for massive amounts of information. By using queries, we can access what data we require to process. A database comprises graphs, tables, and columns for displaying information.
SQL Developer Role:
- Being a SQL developer is a term used to describe:
- You are responsible for the design of databases and tables.
- Make views, stored procedures and functions.
- Database triggers that need to be developed for automation.

SQL practice questions:
If you are a developer for SQL, you must be aware of these commands.
- DML The word means DML: Data Manipulation Language.
- DDL Definition Language for Data. Definition Language.
- DCL Control Language for Data. Control Language.
First, DML (Data Manipulation Language) commands are used to edit the data, insert it, or delete it.
The second DDL (Data Definition Language) commands are used to build changes, modify, drop, and truncate tables.
The other refers to DCL (Data Control Language). These commands are employed to Grant, Revoke the database.
Grant: The command grants permission to access the database for users.
The Revoke command revokes the right to access databases granted to users via the grant. Grant command.
SQL TCL Commands:(Transaction control language):

- SAVEPOINT: If you have set a save timer, your game can be resumed.
- SET TRANSACTION: It will define the specifics of the deal.
