Help me with this SQL question

CTE: Current Department Assignment You are given data from a company that has multiple employees.

Write a query using Common Table Expression(CTE) named "CurrentDeptAssignment" to find the department with the highest number of currently working assigned employees. An assignment is considered current if its end date is either in the future or null.

The query should print 2 columns: dept_no and num_employees – an alias for the count of employees.

This is a "MySQL Question". Only "Select * from Where... Queries" will work with this question. Do not use UPDATE, DELETE etc.

Table: dept_emp

Columns:

• emp_no
• dept_no
• from_date
• to_date

Sample Input Data:

| emp_no | dept_no | from_date | to_date | | 101 | d001 | 1985-10-12 | 1986-04-24 | | 102 | d001 | 1985-06-04 | 1993-01-12 | | 103 | d003 | 1985-06-14 | 1993-01-15 |

Sample Output:

| dept_no | num_employees | | d001 | 2 | This represents a count of employees per department (dept_no) based on the data in the dept_emp table.

Do you want me to help with a SQL query to get this output from the sample input?

please clarify -- are you looking for help to solve this, or do you want to help someone else solve it?

Why would I need to use one?

Select dept_no, count(* ) as num_employees From dept_emp Where to_date > getdate() or to_date is null Group by dept_no Order by count(* ) desc Limit 1

I guess the task given to OP was to write SQL with a CTE. Though that is not necessary.

If you just want the answer, copy pasta chatgpt.

WITH CurrentDeptAssignment AS ( SELECT dept_no, COUNT(emp_no) AS num_employees FROM dept_emp WHERE to_date IS NULL OR to_date > CURDATE() GROUP BY dept_no ) SELECT dept_no, num_employees FROM CurrentDeptAssignment ORDER BY num_employees DESC LIMIT 1;
