SELECT INTO(7)		 PostgreSQL 17.5 Documentation		SELECT INTO(7)

NAME
       SELECT_INTO - define a new table	from the results of a query

SYNOPSIS
       [ WITH [	RECURSIVE ] with_query [, ...] ]
       SELECT [	ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
	   [ { * | expression [	[ AS ] output_name ] } [, ...] ]
	   INTO	[ TEMPORARY | TEMP | UNLOGGED ]	[ TABLE	] new_table
	   [ FROM from_item [, ...] ]
	   [ WHERE condition ]
	   [ GROUP BY expression [, ...] ]
	   [ HAVING condition ]
	   [ WINDOW window_name	AS ( window_definition ) [, ...] ]
	   [ { UNION | INTERSECT | EXCEPT } [ ALL | DISTINCT ] select ]
	   [ ORDER BY expression [ ASC | DESC |	USING operator ] [ NULLS { FIRST | LAST	} ] [, ...] ]
	   [ LIMIT { count | ALL } ]
	   [ OFFSET start [ ROW	| ROWS ] ]
	   [ FETCH { FIRST | NEXT } [ count ] {	ROW | ROWS } ONLY ]
	   [ FOR { UPDATE | SHARE } [ OF table_name [, ...] ] [	NOWAIT ] [...] ]

DESCRIPTION
       SELECT INTO creates a new table and fills it with data computed by a
       query. The data is not returned to the client, as it is with a normal
       SELECT. The new table's columns have the	names and data types
       associated with the output columns of the SELECT.

PARAMETERS
       TEMPORARY or TEMP
	   If specified, the table is created as a temporary table. Refer to
	   CREATE TABLE	(CREATE_TABLE(7)) for details.

       UNLOGGED
	   If specified, the table is created as an unlogged table. Refer to
	   CREATE TABLE	(CREATE_TABLE(7)) for details.

       new_table
	   The name (optionally	schema-qualified) of the table to be created.

       All other parameters are	described in detail under SELECT(7).

NOTES
       CREATE TABLE AS is functionally similar to SELECT INTO.	CREATE TABLE
       AS is the recommended syntax, since this	form of	SELECT INTO is not
       available in ECPG or PL/pgSQL, because they interpret the INTO clause
       differently. Furthermore, CREATE	TABLE AS offers	a superset of the
       functionality provided by SELECT	INTO.

       In contrast to CREATE TABLE AS, SELECT INTO does	not allow specifying
       properties like a table's access	method with USING method or the
       table's tablespace with TABLESPACE tablespace_name. Use CREATE TABLE AS
       if necessary. Therefore,	the default table access method	is chosen for
       the new table. See default_table_access_method for more information.

EXAMPLES
       Create a	new table films_recent consisting of only recent entries from
       the table films:

	   SELECT * INTO films_recent FROM films WHERE date_prod >= '2002-01-01';

COMPATIBILITY
       The SQL standard	uses SELECT INTO to represent selecting	values into
       scalar variables	of a host program, rather than creating	a new table.
       This indeed is the usage	found in ECPG (see Chapter 34) and PL/pgSQL
       (see Chapter 41). The PostgreSQL	usage of SELECT	INTO to	represent
       table creation is historical. Some other	SQL implementations also use
       SELECT INTO in this way (but most SQL implementations support CREATE
       TABLE AS	instead). Apart	from such compatibility	considerations,	it is
       best to use CREATE TABLE	AS for this purpose in new code.
