SELECT is used to retrieve rows selected from one or more tables, and
can include UNION statements and subqueries. See [union], and
[subqueries].

The most commonly used clauses of SELECT statements are these:

o Each select_expr indicates a column that you want to retrieve. There
  must be at least one select_expr.

o table_references indicates the table or tables from which to retrieve
  rows. Its syntax is described in [join].

o The WHERE clause, if given, indicates the condition or conditions
  that rows must satisfy to be selected. where_condition is an
  expression that evaluates to true for each row to be selected. The
  statement selects all rows if there is no WHERE clause.

  In the WHERE clause, you can use any of the functions and operators
  that MySQL supports, except for aggregate (summary) functions. See
  [functions].

SELECT can also be used to retrieve rows computed without reference to
any table.
