Refer to the tables. Which query produces the result table below?

Question

BlackTom AI · Accepted Answer

The task asks us to identify which query would produce a specific result table, given the provided question details.

First, note that the question references a result table that is not shown in the prompt, and the available data for answer options is empty. Because there are no listed alternative queries to compare, we cannot perform a side-by-side analysis of multiple choices. Instead, we can reason about what the single provided query would produce and how that relates to a typical expected result table of the described form.

The given query is:
SELECT S.OrderId, P.ProductName, P.UnitPrice * S.Quantity AS SubTotal 
FROM Sales S 
INNER JOIN Product P ON S.ProductId = P.ProductId;

- It selects three columns: OrderId from the Sales table (aliased as S), ProductName from the Product table (aliased as P), and a computed column SubTotal which multiplies UnitPrice from the Product table by Quantity from the Sales table. 
- It uses an INNER JOIN between Sales and Product on the matching ProductId fields, which means only rows with a corresponding product in the Product table will appear in the result. This is typical for queries that want to show order details along with product information, ensuring there are no orphaned sales records without a product.
- The fields chosen correspond to common elements you’d expect in a result table that lists each order item, including the order identifier, the product description, and the line-item subtotal (price times quantity).

If the target result table is intended to show, for each order item, its order identifier, the product name, and the calculated subtotal, then this query aligns with that goal because:
- OrderId ties the row to a specific order, enabling aggregation or grouping by order later if needed.
- ProductName provides a readable product descriptor alongside the numeric values.
- SubTotal directly computes the revenue contribution of that line item, derived from unit price and quantity, which is a common requirement for financials or order detail displays.

Potential considerations worth verifying when matching to the target result:
- Data integrity: if there are any sales records with a ProductId that does not exist in the Product table, the INNER JOIN would exclude those rows. If the target table is supposed to include all sales rows regardless of product presence, a LEFT JOIN might be more appropriate.
- Aliasing clarity: the use of table aliases S and P helps keep the query concise, which is good practice for readability and maintenance.
- Calculation correctness: the expression P.UnitPrice * S.Quantity assumes UnitPrice is a numeric type and Quantity is numeric; if there are nulls, result semantics depend on the database system (typical behavior is that any null yields a null SubTotal for that row).

If there were alternative queries, you would compare them by checking whether they select the same three columns in the same order, whether they join the same tables on the same keys, and whether the computed SubTotal expression matches the intended calculation. In this case, since only one query is provided and no other options are available for comparison, the reasoning centers on understanding what this query would yield and how that aligns with a standard expected result table for an order-item detail view.
