Multiple Choice

Which statement best describes the WHERE clause in SQL?

The concept here is how a SQL WHERE clause filters rows based on a condition. It specifies criteria that rows must meet to be included in the result set (or to be affected by an UPDATE or DELETE). For example, selecting employees with a condition like department = 'Sales' and salary > 50000 returns only those rows that satisfy both criteria. This is different from creating a new table, which uses commands like CREATE TABLE or a SELECT INTO destination table. It’s also different from sorting results, which is done with ORDER BY, and from computing aggregates, which uses GROUP BY along with aggregate functions such as SUM or AVG. So the WHERE clause is the mechanism that narrows down the data by applying logical conditions to determine which rows should be returned or acted upon.
