Which SQL command is recommended for querying a report showing all students enrolled in courses along with their grades?

• A. SELECT ... FROM Enrollments
• B. UPDATE ... FROM Enrollments
• C. DELETE ... FROM Enrollments
• D. INSERT ... INTO Enrollments

Answer: (A)

The recommended SQL command for querying a report showing all students enrolled in courses along with their grades is to use the SELECT statement. This command is specifically designed for retrieving data from a database. By using the SELECT statement, you can specify the particular fields you want to include in your report, such as student names, course titles, and their respective grades from the Enrollments table. This allows you to pull together the necessary information to create a comprehensive report on student enrollments and academic performance. The other options, although they are valid SQL commands, serve entirely different purposes. The UPDATE command is used to modify existing records in the database, which would not be appropriate for merely retrieving information. The DELETE command removes records from the database, which also does not align with the goal of generating a report. Lastly, the INSERT command adds new records to the database, which is not relevant when you are looking to query existing data. Therefore, the best and most appropriate command for the given task is the SELECT statement.
