A data specialist is preparing a report of entries that exceed a threshold for the current quarter. The dataset contains repeated rows, so the specialist wants to exclude duplicates. Which method is the best for filtering these entries?
Filter records by adding an ORDER BY clause on the threshold and delete repeated values in a separate step
Use a SELECT DISTINCT statement with a WHERE clause to find rows over the threshold
Create a subquery to get rows under the threshold and exclude them from the main query
Group every column with GROUP BY and then apply an aggregate function to remove duplicates
Using SELECT with DISTINCT for the relevant columns and a WHERE clause is effective for retrieving rows that meet the threshold for the current quarter while eliminating repeated entries. ORDER BY and other aggregate approaches do not necessarily remove duplicates in the desired way. Subqueries that exclude certain values may not address repeated rows.
