SQL Introduction

I want to discuss about SQL Introduction for beginners.

SQL is Structured Query language. SQL is an ANSI (American National Standards Institute) standard.

There are 4 categories in SQL command:

  1. Data Definition language (DDL)
  2. Data Manipulation Language (DML)
  3. Data Control Language(DCL)
  4. Transaction Control(TCL)

Data Definition language :   CREATE, ALTER, RENAME, DROP

Data Manipulation Language :  INSERT, SELECT, UPDATE and DELETE

Data Control Language : GRANT, REVOKE

Transaction Control : COMMIT, SAVEPOINT, ROLLBACK

Thank you for reading SQL Introduction.
