Select into temp table in PostgreSQL? [duplicate]

Question

How to create temporary table using select into in PostgreSQL. For example in SQL Select * into temp_tab from source_tab;

Answer 1

You can try to use Create Table As command like this:

CREATE TEMP TABLE mytable AS SELECT * from source_tab; 

From the docs:

This command is functionally similar to SELECT INTO, but it is preferred since it is less likely to be confused with other uses of the SELECT INTO syntax. Furthermore, CREATE TABLE AS offers a superset of the functionality offered by SELECT INTO.

The CREATE TABLE AS command allows the user to explicitly specify whether OIDs should be included. If the presence of OIDs is not explicitly specified, the default_with_oids configuration variable is used.
