Sample Solution:
-- Selecting specific columns from the vSalesPerson view
SELECT
-- Selecting the TerritoryName column
TerritoryName,
-- Selecting the BusinessEntityID column
BusinessEntityID,
-- Selecting the SalesYTD column
SalesYTD,
-- Using the LEAD window function to get the next SalesYTD, defaulting to 0 if not available
LEAD(SalesYTD, 1, 0) OVER (
-- Partitioning the data by TerritoryName and ordering by SalesYTD in descending order
PARTITION BY TerritoryName
ORDER BY SalesYTD DESC
) AS NextRepSales
-- Filtering data from the vSalesPerson view
FROM
Sales.vSalesPerson
-- Filtering records for territories named 'Northwest' and 'Canada'
WHERE
TerritoryName IN ('Northwest', 'Canada')
-- Ordering the result set by TerritoryName
ORDER BY
TerritoryName;
Explanation:
- This SQL code operates on a view named Sales.vSalesPerson.
- It retrieves data related to salespersons from territories named 'Northwest' and 'Canada'.
- The retrieved data includes the TerritoryName, BusinessEntityID, and SalesYTD (sales year-to-date).
- The LEAD window function is used to fetch the next value of SalesYTD within each territory partition, with a default of 0 if the next value is not available.
- The data is partitioned by TerritoryName and ordered by SalesYTD in descending order within each partition.
- The result set is ordered by TerritoryName.
Sample Output:
