Response in English: Here is a sample SQL query to find the average salary of employees from the Sales department:SELECT AVGsalary as avg_sales_salary FROM employeesINNER JOIN departments ON employees.department_id departments.department_idWHERE departments.department_name Sales ;This query starts by selecting the average of the column salary in the employees table and assigns the alias avg_sales_salary to the result. The AVG function calculates the average value of a numeric column. This query then performs an INNER JOIN between the employees table and the departments table on the department_id column present in both tables. Finally, the WHERE clause filters the results of the joined table to only include rows where the department_name is Sales in the departments table. And us result returns the average salary for the sales department only. .
