See Section 13.2.10.3, “UNION Clause”, and Section 13.2.11, “Subqueries”. A SELECT statement can start with a WITH clause to define common table expressions accessible within the SELECT. See Section 13.2.15, “WITH (Common Table Expressions)”. The most commonly used clauses of SELECT statements are these:
SELECT can also be used to retrieve rows computed without reference to any table. For example: mysql> SELECT 1 + 1; -> 2You are permitted to specify DUAL as a dummy table name in situations where no tables are referenced: mysql> SELECT 1 + 1 FROM DUAL; -> 2DUAL is purely for the convenience of people who require that all SELECT statements should have FROM and possibly other clauses. MySQL may ignore the clauses. MySQL does not require FROM DUAL if no tables are referenced. In general, clauses used must be given in exactly the order shown in the syntax description. For example, a HAVING clause must come after any GROUP BY clause and before any ORDER BY clause. The INTO clause, if present, can appear in any position indicated by the syntax description, but within a given statement can appear only once, not in multiple positions. For more information about INTO, see Section 13.2.10.1, “SELECT ... INTO Statement”. The list of select_expr terms comprises the select list that indicates which columns to retrieve. Terms specify a column or expression or can use *-shorthand:
The following list provides additional information about other SELECT clauses:
Following the SELECT keyword, you can use a number of modifiers that affect the operation of the statement. HIGH_PRIORITY, STRAIGHT_JOIN, and modifiers beginning with SQL_ are MySQL extensions to standard SQL.
