Sample Solution:

-- Creating a Common Table Expression (CTE) named OrderedOrders
WITH OrderedOrders AS  
(  
    -- Selecting specific columns from the SalesOrderHeader table and calculating row numbers based on OrderDate
    SELECT 
        SalesOrderID, 
        OrderDate,  
        -- Calculating row numbers based on OrderDate
        ROW_NUMBER() OVER (ORDER BY OrderDate) AS RowNumber  
    FROM 
        Sales.SalesOrderHeader   
)   
-- Selecting columns from the OrderedOrders CTE
SELECT 
    SalesOrderID, 
    OrderDate, 
    RowNumber    
FROM 
    OrderedOrders   
-- Filtering records where RowNumber falls between 50 and 60
WHERE 
    RowNumber BETWEEN 50 AND 60;

Explanation:

• This SQL code creates a Common Table Expression (CTE) named OrderedOrders to calculate row numbers based on the OrderDate column.
• The CTE selects specific columns (SalesOrderID and OrderDate) from the SalesOrderHeader table and calculates row numbers (RowNumber) using the ROW_NUMBER() function, ordering the rows by OrderDate.
• After defining the CTE, the main query selects columns from the OrderedOrders CTE.
• The main query filters records where the RowNumber falls between 50 and 60, effectively retrieving rows ranked between 50th and 60th based on OrderDate.
• The result set will contain SalesOrderID, OrderDate, and the corresponding row numbers for orders falling within the specified row number range.
