Sample Solution:
-- Selecting the common ProductID values between the Product and WorkOrder tables using the INTERSECT operator
SELECT
-- Selecting the ProductID column from the Product table
ProductID
-- Selecting data from the Product table
FROM
Production.Product
-- Applying the INTERSECT operator to find the common ProductID values between the two queries
INTERSECT
-- Selecting the ProductID column from the WorkOrder table
SELECT
ProductID
-- Selecting data from the WorkOrder table
FROM
Production.WorkOrder ;
Explanation:
- This SQL code retrieves common ProductID values between the Product and WorkOrder tables using the INTERSECT operator.
- The first SELECT statement selects ProductID values from the Product table.
- The second SELECT statement selects ProductID values from the WorkOrder table.
- The INTERSECT operator combines the results of the two SELECT statements and returns only the common ProductID values present in both tables.
- The result set will contain ProductID values that exist in both the Product and WorkOrder tables, effectively identifying products that are part of work orders.
