Sql, Query

A query is a request for data or information from a database table or combination of tables.

#3

In a relational database, a query is an instruction to the database management system (DBMS) to either retrieve some data or modify some data.

A very important key to understanding queries is that, unlike traditional third generation programming languages, the query does not spell out the steps the computer has to take. The query defines the desired result. It is up to the DBMS to work out the most efficient series of steps to get that result.
