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.
