Nationalities with Multiple Artists in Database

2. List all the nationalities with more than one artist represented in the database, and the number of artists of that nationality. there is artist tablle,work table

To list all nationalities with more than one artist represented in a database, you would typically use a SQL query to count the number of artists for each nationality in the artist table. Assuming the artist table has a column for nationality, the SQL query would look something like this:

SELECT nationality, COUNT(*) AS artist_count
FROM artist
GROUP BY nationality
HAVING COUNT(*) > 1;

Explanation:

• SELECT nationality, COUNT(*) AS artist_count: This selects the nationality and counts the number of artists for each nationality.
• FROM artist: This specifies the table from which to retrieve the data.
• GROUP BY nationality: This groups the results by nationality so that the count is calculated for each group.
• HAVING COUNT(*) > 1: This filters the results to include only those nationalities that have more than one artist.

Result:

The result of this query will be a list of nationalities along with the count of artists for each nationality that has more than one artist in the database.

Make sure to adjust the column names and table names if they differ in your actual database schema.
