## SELECT INTO 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](sql-createtable.html) for details. `UNLOGGED` If specified, the table is created as an unlogged table. Refer to [CREATE TABLE](sql-createtable.html) for details. *`new_table`* The name (optionally schema-qualified) of the table to be created. All other parameters are described in detail under [SELECT](sql-select.html). ## Notes [`CREATE TABLE AS`](sql-createtableas.html) 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`*`](sql-createtable.html#SQL-CREATETABLE-METHOD) or the table's tablespace with [`TABLESPACE *`tablespace_name`*`](sql-createtable.html#SQL-CREATETABLE-TABLESPACE). Use `CREATE TABLE AS` if necessary. Therefore, the default table access method is chosen for the new table. See [default\_table\_access\_method](runtime-config-client.html#GUC-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 36](ecpg.html)) and PL/pgSQL (see [Chapter 43](plpgsql.html)). 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. ## See Also [CREATE TABLE AS](sql-createtableas.html)
