In MySQL, you can check the time difference between two date or datetime values using the
TIMEDIFF() function. Here is an example of how to use it in a query:
SELECT TIMEDIFF(end_time, start_time) AS time_difference FROM your_table;
In the above example,
start_time are the columns in the
your_table table representing the end and start times respectively.
TIMEDIFF() function calculates the difference between the two given datetime values and returns the result as a time value. You can then alias this result as
time_difference to make it easier to reference in the query result.
Note that the
TIMEDIFF() function will return a negative value if the end time is earlier than the start time.
