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