SELECT is used to retrieve rows selected from one or more tables, and
can include UNION operations and subqueries. Beginning with MySQL
8.0.31, INTERSECT and EXCEPT operations are also supported. The UNION,
INTERSECT, and EXCEPT operators are described in more detail later in
this section. See also
https://dev.mysql.com/doc/refman/8.0/en/subqueries.html.

A SELECT statement can start with a WITH clause to define common table
expressions accessible within the SELECT. See
https://dev.mysql.com/doc/refman/8.0/en/with.html.

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 [HELP JOIN].

o SELECT supports explicit partition selection using the PARTITION
  clause with a list of partitions or subpartitions (or both) following
  the name of the table in a table_reference (see [HELP JOIN]). In this
  case, rows are selected only from the partitions listed, and any
  other partitions of the table are ignored. For more information and
  examples, see
  https://dev.mysql.com/doc/refman/8.0/en/partitioning-selection.html.

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 expression, you can use any of the functions and
  operators that MySQL supports, except for aggregate (group)
  functions. See
  https://dev.mysql.com/doc/refman/8.0/en/expressions.html, and
  https://dev.mysql.com/doc/refman/8.0/en/functions.html.

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