What is the result of the following query?  `SELECT COUNT(*) FROM employees WHERE salary > 5000;`

Let's parse the SQL statement and the structure of the query results to understand what is being asked.
Option 1: 'Returns the sum of salaries' would be produced by an aggregate function like SUM(salary), not by COUNT(*). Since the query uses COUNT(*) with a WHERE condition, this option describes a different aggregate and is not what the query returns.
Option 2: 'Returns the minimum salary' would require an aggregate function like MIN(salary). The given query does not compute a minimum; it counts rows that satisfy the condition, so this option misinterprets the operation being performed.
Option 3: 'Returns the total number of employees with salary greater than 5000' accurately reflects COUNT(*) with a WHERE salary > 5000. COUNT(*) tallies all rows that meet the condition, and here those rows correspond to employees whose salary exceeds 5000. This matches the semantics of the query precisely.
Option 4: 'Returns the total number of employees' would be produced by COUNT(*) without any WHERE clause. Since there is a WHERE clause filtering by salary > 5000, counting all employees regardless of salary is incorrect for this query.
In summary, the query applies a filter (salary > 5000) and then counts how many rows satisfy that filter. The option that describes this behavior—the count of employees whose salary is greater than 5000—is the one that aligns with COUNT(*) combined with the WHERE condition.
