569. Median Employee Salary

Leetcode Solutions

Using Window Functions to Calculate Median Salary

Use the ROW_NUMBER() window function to assign a row number to each salary within each company, ordered by salary and id.
Use the COUNT() window function to get the total number of employees in each company.
Calculate the positions of the median salary based on the total count (if the count is odd, use (count + 1) / 2; if even, use count / 2 and count / 2 + 1).
Filter the rows where the row number matches the median positions calculated in the previous step.
Select the id, company, and salary columns from the filtered rows.
