2. Understand what filtering results means in the context of an SQL query.

Relevant Concepts

1. GROUP BY: This clause is used to group rows that have the same values in specified columns into summary rows.
2. ORDER BY: This clause is used to sort the result set of a query in ascending or descending order.
3. WHERE: This clause is used to filter records that meet specific criteria.
4. FILTER: This is not a standard SQL clause for filtering records in the way WHERE does.

Analysis and Detail

2. ORDER BY deals with the ordering of results but does not reduce the set of returned data.
3. WHERE allows you to specify conditions to filter the records returned by the query. It is the standard SQL clause for filtering rows based on certain criteria.
4. FILTER is not a widely recognized standard in SQL for simply filtering results; it is more commonly associated with window functions in some SQL implementations.
