Sample Solution:
-- Selecting a concatenated string containing product details and color information, along with the color column itself
SELECT CONCAT( name, ' color:-',color,' Product Number:', productnumber ) AS result, color
-- From the Production schema's Product table
FROM production.product;
Explanation:
- The SQL query retrieves data from the Product table within the Production schema.
- It constructs a concatenated string using the CONCAT() function to combine various elements such as name, color, and product number.
- The CONCAT() function concatenates multiple strings together.
- In the concatenated string:
- name represents the product name.
- ' color:-' is a separator text indicating the start of the color information.
- color represents the color of the product.
- ' Product Number:' is a separator text indicating the start of the product number information.
- productnumber represents the product number.
- The concatenated string is aliased as 'result'.
- The color column is also selected separately.
Sample Output:
