Answer 1

Below are the SQL queries with output screenshots

1. List the first name, last name, and region of members who do not have an email.

Select FirstName, Lastname, Region From Members where Email IS NULL

Below is the output from given database

************************************************************************

2. List the first name, last name, and region of members who do not have an email and they either have a homephone ending with a 2 or a 3.

Select FirstName, Lastname, Region From Members where Email IS NULL AND (HomePhone LIKE '%2' OR HomePhone LIKE '%3');

Below is the output from given database

************************************************************************

3. List the number of track titles that begin with the letter 's' and the average length of these tracks in seconds

SELECT COUNT(TrackTitle) As NumberOfTracksStartsWithS, AVG(LengthSeconds) As Averagelength FROM Tracks WHERE TrackTitle LIKE 's%'

Below is the output from given database

************************************************************************

4. Report the number of members by state and gender. Sort the results by the region

SELECT Region,
COUNT(CASE WHEN UPPER(Gender) = 'M' THEN 1 END) AS Male,
COUNT(CASE WHEN UPPER(Gender) = 'F' THEN 1 END) AS Female
FROM Members GROUP BY Region 
Order By Region

Below is the output from given database

************************************************************************

Explanation for abpve used queries.

Below are the syntax for select statemens

SELECT column1, column2, ...
FROM table_name;

In above syntax you can add whatever columns you want to retrieve from table by sparating with comma.

where Email IS NULL - This conditon will retrieve to data for which email is null.

SELECT COUNT(TrackTitle) As NumberOfTracksStartsWithS, AVG(LengthSeconds) As Averagelength FROM Tracks WHERE TrackTitle LIKE 's%'

WHERE TrackTitle LIKE 's%' - This condition to get all whose Track title starts with s

COUNT(TrackTitle) - This will give you the count whose title track starts with s

SELECT Region,
COUNT(CASE WHEN UPPER(Gender) = 'M' THEN 1 END) AS Male,
COUNT(CASE WHEN UPPER(Gender) = 'F' THEN 1 END) AS Female
FROM Members GROUP BY Region
Order By Region

CASE WHEN UPPER(Gender) = 'M' - We are using CASE to name column as Male when Geneder is M

CASE WHEN UPPER(Gender) = 'F' - We are using CASE to name column as Female when Geneder is F

Order By Region - This will sort the results by region column.
