How to retrieve the last inserted ID using the RETURNING clause in a PostgreSQL INSERT statement

When performing an INSERT operation in PostgreSQL, you can utilize the RETURNING clause to retrieve the last inserted ID. This can be particularly useful when you need to obtain the generated ID for further manipulation or referencing in your application.

To achieve this, simply include the RETURNING statement after your INSERT query, specifying the ID column that you want to retrieve. Here is an example:

INSERT INTO your_table (column1, column2)
VALUES (value1, value2)
RETURNING id;

In this example, "your_table" is the name of your table, and "id" is the ID column that you want to retrieve. By executing this query, PostgreSQL will return the ID of the last inserted row, which you can then capture and use in your application logic.

By using the RETURNING clause in your PostgreSQL INSERT statements, you can easily retrieve the last inserted ID and streamline your database operations.
