Sample Solution:

-- Concatenating a string with the due date converted to a VARCHAR data type
SELECT CONCAT('The order is due on ', CAST(DueDate AS VARCHAR(12)))  
-- From the Sales.SalesOrderHeader table
FROM Sales.SalesOrderHeader  
-- Filtering records where the SalesOrderID is 50001
WHERE SalesOrderID = 50001;

Explanation:

• This SQL query retrieves data from the SalesOrderHeader table in the Sales schema.
• Comments are added to explain each part of the query for better understanding and maintenance.
• Here's a breakdown of what the query does:
• The SELECT clause concatenates a string 'The order is due on ' with the DueDate column converted to a VARCHAR data type.
• The CAST function is used to convert the DueDate column to a VARCHAR data type with a length of 12 characters.
• The result is a string that represents the due date of the order.
• The FROM clause specifies the SalesOrderHeader table from which data is being retrieved.
• The WHERE clause filters records where the SalesOrderID is equal to 50001, indicating a specific order.

Sample Output:

concat                          |

The order is due on 2013-03-22 0|
