postgresqlHow do I create a temporary table in PostgreSQL?

Creating a temporary table in PostgreSQL is a simple process. Here is an example of how to do it:

-- Create a temporary table
CREATE TEMP TABLE items (
  id INTEGER,
  name VARCHAR(50)
);

-- Insert some data
INSERT INTO items (id, name)
VALUES (1, 'Apple'), (2, 'Banana'), (3, 'Orange');

-- Select the data
SELECT * FROM items;

-- Output
id  |  name
----+--------
 1  |  Apple
 2  |  Banana
 3  |  Orange

The code above creates a temporary table called items with two columns, id and name. Then it inserts a few rows of data into the table. Finally, it selects the data from the table and prints the output.

The key parts of the code are:

• CREATE TEMP TABLE - creates a temporary table
• INSERT INTO - inserts data into the table
• SELECT * FROM - selects data from the table

For more information, see the PostgreSQL documentation:

• CREATE TABLE
• INSERT
• SELECT
