Mysql – How to subtract using SQL in MYSQL between two date time values and retrieve the result in minutes or second

datemysqlsql

I want to subtract between two date time values using SQL in MySQL such that I get the interval in minutes or seconds. Any ideas? I want to run a SQL query that retrieves uses from a database who have logged in like 10 minutes from the time.

Best Solution

There are functions TIMEDIFF(expr1,expr2), which returns the value of expr1-expr2, and TIME_TO_SEC(expr3), which expresses expr3 in seconds.

Note that expr1 and expr2 are datetime values, and expr3 is a time value only.
