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'
|United States of America||295000000|
- The SELECT line determines which columns to show - in this case
population, both of which are columns of the bbc ta le.
- The WHERE clause determines which rows to show
