Structured Query Language

Structured Query Language (SQL) is a language used to view or change data in databases. The sentences used in this language are called SQL Queries. If we want to add data to the database in a computer, or to remove data from the database, or to just view the data in the database, we can use SQL Queries.

Examples

This is a simple SQL Query which is used to show a column named 'my_column' of the data table named 'my_table'.

SELECT my_column FROM my_table;
