DATABASE(SQL) LEETCODE PROBLEMS PART 6

In this video, we solve LeetCode SQL Problem 1741 – Find Total Time Spent by Each Employee. This problem involves calculating the total number of hours each employee worked per day. The input table, Employees, contains records of login and logout times (in hours) for different days. To solve this, we: Subtract in_time from out_time to find the duration of each session. Group the records by event_day and emp_id to aggregate sessions for the same employee on the same day. Use SUM() to compute the total time spent. Return the results sorted by day and employee ID if needed. This problem helps you practice: Basic arithmetic operations in SQL Grouping and aggregation with GROUP BY and SUM() Understanding time calculations using integer fields representing hours This is a great example of how SQL can transform raw log data into meaningful summaries about employee activity. #LeetCodeSQL #SQLAggregation #SQLGROUPBY #EmployeeTimeTracking #SQLPractice #DatabaseQueries If you’d like, I can tweak this for a YouTube video description or other formats.
