  Score: 10/10

  Please read all records of the departments table (display all fields: id, name, budget); if the number of records exceeds 10, return only the first 10 rows; also return the total number of records in this table.

  Here are the details from the "departments" table:

• Test case 4

  Score: 9/10

  Please group the employees table by the department field, and calculate the salary statistics of employees in each department: 1. Total number of employees in the department; 2. Total salary of the department; 3. Average salary of the department (rounded to 2 decimal places); finally, sort by average salary in descending order, and display the department, total number of employees, total salary, and average salary fields.

  Here are the salary statistics grouped by department:

  Department	Total Employees	Total Salary	Average Salary
  Engineering	2	$155,000	$77,500.00
  Marketing	1	$65,000	$65,000.00
  Sales	1	$60,000	$60,000.00
  HR	1	$55,000	$55,000.00

  Summary

  • Engineering has the highest average salary at $77,500.
  • All other departments have only one employee, leading to their average salaries being equal to their total salaries.
• Test case 5

  Score: 9/10

  Please join the departments table (by the name field) and the employees table (by the department field), and calculate the ratio of "total salary expenditure" to "department budget" for each department (ratio = total salary expenditure / budget * 100%, rounded to 2 decimal places); display the department name, budget, total salary expenditure, and salary budget ratio fields, sorted by ratio in descending order.

  Here are the results of the query showing the ratio of total salary expenditure to department budget for each department:

  Department Name	Budget	Total Salary Expenditure	Salary Budget Ratio (%)
  HR	150,000	55,000	36.67
  Marketing	200,000	65,000	32.50
  Engineering	500,000	155,000	31.00
  Sales	300,000	60,000	20.00

  The data is sorted by the salary budget ratio in descending order.
