SELECT INTO

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 ] [, ...] ]
    [ LIMIT { count | ALL } ]
    [ OFFSET start ]
    [ FOR UPDATE [ OF tablename [, ...] ] ]

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

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

NOTES

CREATE TABLE AS [create_table_as(7)] is functionally equivalent 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.

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 and PL/pgSQL. 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.)
