Create calculated columns joining names and minutes/seconds together

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 select the artist name and type, and add a third calclulated column which joins them together:

Artists and types

Here we're listing the artists in alphabetical order.

You can add the bits of text together using the + operator, or use the CONCAT function to do this.

Write another query which selects the following fields from the Track table, with a critieria to show only those tracks containing the text string in their names:

Tracks containing string

The tracks you should see.

Replace the Track_mins and Track_secs columns with a calculated column which concatenates the values as shown in the diagram below:

Track lengths using concat

Again you could either us the concat function or the + operator to achieve this.

Save the script as strings attached.sql and then close it.
