Question
Assume you have two tables in a database: employees and departments.employees table:employee_id (Primary Key)namedepartment_id (Foreign Key referencing departments.department_id)departments table:department_id (Primary Key)department_nameNow, write an SQL query to retrieve the names of employees along with their corresponding department names.
Solution
Sure, here is the SQL query you need:
SELECT employees.name, departments.department_name
FROM employees
INNER JOIN departments
ON employees.department_id = departments.department_id;
This query works as follows:
-
SELECT employees.name, departments.department_name: This part of the query specifies the columns that you want to retrieve. In this case, you want the name of the employee from the employees table and the department_name from the departments table. -
FROM employees: This part of the query specifies the main table you are selecting from, which is the employees table in this case. -
INNER JOIN departments: This part of the query specifies the table you want to join with the main table. An INNER JOIN returns records that have matching values in both tables. In this case, you are joining the departments table with the employees table. -
ON employees.department_id = departments.department_id: This part of the query specifies the condition for the join. You are joining on the condition where the department_id in the employees table matches the department_id in the departments table. This ensures that you get the department_name corresponding to each employee.
