Sample Solution:

-- Selecting the time difference between the maximum and minimum OrderDate values from the SalesOrderHeader table
SELECT 
    -- Calculating the time difference between the maximum and minimum OrderDate values
    max(OrderDate) - min(OrderDate) 

-- Selecting data from the SalesOrderHeader table
FROM 
    Sales.SalesOrderHeader;

Explanation:

This SQL code operates on a table named Sales.SalesOrderHeader.
It calculates the time difference between the maximum and minimum OrderDate values.
The max(OrderDate) function returns the maximum (latest) OrderDate value from the SalesOrderHeader table.
The min(OrderDate) function returns the minimum (earliest) OrderDate value from the SalesOrderHeader table.
By subtracting the minimum OrderDate from the maximum OrderDate, you get the time duration between the earliest and latest orders.
The result will be the time difference expressed in the appropriate units based on the data type of the OrderDate column (e.g., days, hours, minutes).

Sample Output:

1126 days|
