SELECT
NAME
SELECT INTO - create a new table from the results of a query
SYNOPSIS
SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
* | expression [ AS output_name ] [, ...]
INTO [ TEMPORARY | TEMP ] [ TABLE ] new_table
[ FROM from_item [, ...] ]
[ WHERE condition ]
[ GROUP BY expression [, ...] ]
[ HAVING condition [, ...] ]
[ { UNION | INTERSECT | EXCEPT } [ ALL ] select ]
[ ORDER BY expression [ ASC | DESC | USING operator ] [, ...] ]
[ FOR UPDATE [ OF tablename [, ...] ] ]
[ LIMIT [ start , ] { count | ALL } ]
[ OFFSET start ]
where from_item can be:
[ ONLY ] table_name [ * ]
[ [ AS ] alias [ ( column_alias_list ) ] ]
|
( select )
[ AS ] alias [ ( column_alias_list ) ]
|
from_item [ NATURAL ] join_type from_item
[ ON join_condition | USING ( join_column_list ) ]
INPUTS
TEMPORARY
TEMP If TEMPORARY or TEMP is specified, the output table is created only
within this session, and is automatically dropped on session exit.
Existing permanent tables with the same name are not visible (in this
session) while the temporary table exists. Any indexes created on a
temporary table are automatically temporary as well.
new_table
The name of the new table to be created. This table must not already
exist. However, a temporary table can be created that has the same
name as an existing permanent table.
All other inputs are described in detail for select(5).
OUTPUTS
Refer to create_table(5) and select(5) for a summary of possible output
messages.
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.
Note: create_table_as(5) is functionally equivalent to SELECT INTO.
CREATE TABLE AS is the recommended syntax, since SELECT INTO is not
standard. In fact, this form of SELECT INTO is not available in
PL/pgSQL or ecpg(1), because they interpret the INTO clause
differently.
COMPATIBILITY
SQL92 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 PL/pgSQL and ecpg(1). The PostgreSQL usage of SELECT
INTO to represent table creation is historical. It's best to use CREATE
TABLE AS for this purpose in new code. (CREATE TABLE AS isn't standard
either, but it's less likely to cause confusion.)
