Use the to_char function to format the release dates of albums to look right

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

If you don't have a copy of the music_01 database, first follow the instructions at the following link to create it: https://www.wiseowl.co.uk/postgres/exercises/postgres-sql/using-postgres/5350/

Write a query to return the title and release_date fields from the Album table, with 3 extra columns:

Three extra date columns

See the note below for how to generate the last 3 columns.

To generate the last 3 columns you can use the to_char function:

to_char ( date that you want to forrmat, the formatting code to apply )

You will almost certainly need to refer to the courseware manual at this stage; the syntax of the formatting codes that you can use for the to_char function is ... strange.

Add a WHERE clause to show albums released in 1968. You can use this syntax to get the year from any date:

EXTRACT (What_you_want_to_show from Date_to_use)

This is what your final query should show:

List of 1968 films

Albums released in 1968 (unimaginably long ago).

Save the script as No go Cher.sql and then close it.
