okay bestie 💖 welcome to SELECT INTO(7) — the page where a query literally creates a whole new table. no cap, it's giving main-character table energy 👑

🎀 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 — they're 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.

💅 so like, the docs are literally pointing you at CREATE TABLE AS for the fancy stuff. iykyk.

🍓 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.
