When performing aJOIN operationin MySQL, the ON clause specifies thejoining condition, defining which columns from both tables should be matched.
Example:
sql
SELECT Employees.Name, Departments.DepartmentName
FROM Employees
JOIN Departments ON Employees.DepartmentID = Departments.ID;
Option A (Incorrect):AS is used foraliasing tables and columns, not for specifying join conditions.
Option B (Incorrect):JOIN defines the type of join (INNER JOIN, LEFT JOIN, etc.), butdoes not specify the columns.
Option C (Correct):The ON clause is used tospecify the join conditionbetween two tables.
Option D (Incorrect):AND is used in filtering conditions, not for joining tables.
