The SELECT command is used to show data from a database.

The output from a SELECT statement is always a grid - with a number of rows and a number of columns. The simplest SELECT commands involve a single table:

SELECT name, population
  FROM bbc
 WHERE region='North America'

<tbody></tbody>

name	population
Canada	32000000
Mexico	106400000
United States of America	295000000

• The SELECT line determines which columns to show - in this case name and population, both of which are columns of the bbc ta le.
• The WHERE clause determines which rows to show
