select_into
SELECT
INTO(7) PostgreSQL 9.2.7 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 (CREATE_TABLE_AS(7)) 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.
Prior to PostgreSQL 8.1, the table created by SELECT INTO included OIDs by default. In PostgreSQL 8.1, this is not the case -- to include
OIDs in the new table, the default_with_oids configuration variable must be enabled. Alternatively, CREATE TABLE AS can be used with the
WITH OIDS clause.
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 33, ECPG - Embedded SQL in C, in the documentation) and PL/pgSQL (see Chapter 39,
PL/pgSQL - SQL Procedural Language, in the documentation). The PostgreSQL usage of SELECT INTO to represent table creation is historical.
It is best to use CREATE TABLE AS for this purpose in new code.
