SQL (Structured Query Language) is a syntax for executing queries.


The SQL language also includes a syntax to update, insert, and delete records.

These query and update commands together form the Data Manipulation Language (DML) part of SQL:


  • SELECT - extracts data from a database table

  • UPDATE - updates data in a database table

  • DELETE - deletes data from a database table

  • INSERT INTO - inserts new data into a database table


The Data Definition Language (DDL) part of SQL permits database tables to be created or deleted. We can also define indexes (keys), specify links between tables, and impose constraints between database tables.

The most important DDL statements in SQL are: 

  • CREATE TABLE - creates a new database table

  • ALTER TABLE - alters (changes) a database table

  • DROP TABLE - deletes a database table

  • CREATE INDEX - creates an index (search key)

  • DROP INDEX - deletes an index
