The SQL command presented utilizes the JOIN clause to combine data from the "instructors" table (aliased as "i") and the "departments" table (aliased as "d"). Option B
How to explain
The query selects columns for the first name, middle name, and last name from the "instructors" table, as well as the department name from the "departments" table.
By matching the "department_id" column in both tables, the JOIN operation merges records where the department IDs match. This results in a comprehensive list displaying the names of all instructors alongside their corresponding department names, offering a consolidated view of the relational data between instructors and departments in the database.
The Complete Question
SQL Code:
SELECT i .first _ name, i. middle _name, i.last _ name, d . department _ name
FROM instructors i
JOIN departments d ON i . department _ i d = d . department_ id;
Finish the SQL command with the conditional clause if needed to show a list of the first, middle, and last names for all instructors and their department names
