Microsoft Fabric Data Engineer Associate DP-700 Practice Question

While testing a report in Microsoft Fabric warehouse, you run this T-SQL: SELECT OrderDate, COUNT(*) AS TotalOrders FROM dbo.SalesOrders WHERE OrderStatus = 'Completed';

It returns error 8120 stating that column 'OrderDate' must appear in the GROUP BY clause. You need the simplest fix so the query returns one row per day with the correct count. Which change should you make?

  • Replace COUNT(*) with COUNT(OrderDate) to include the column in the aggregate.

  • Add a GROUP BY OrderDate clause to the statement.

  • Rewrite the aggregate as COUNT(*) OVER (PARTITION BY OrderDate).

  • Insert the DISTINCT keyword after SELECT to eliminate duplicates.
