How to get the Average on MySQL time column?
To get average on time column, use the below syntax. It will give the average in time format −
SELECT SEC_TO_TIME(AVG(TIME_TO_SEC(yourColumnName))) as anyVariableName from yourTableName;
To understand the above concept, let us create a table. The following is the query −
mysql> create table AverageOnTime −> ( −> PunchInTime time −> ); Query OK, 0 rows affected (0.61 sec)
Insert time values in the table using insert command. The query to insert records is as follows −
mysql> insert into AverageOnTime values('00:00:40');
Query OK, 1 row affected (0.20 sec)
mysql> insert into AverageOnTime values('00:02:50');
Query OK, 1 row affected (0.15 sec)
mysql> insert into AverageOnTime values('00:03:30');
Query OK, 1 row affected (0.13 sec)
mysql> insert into AverageOnTime values('00:04:55');
Query OK, 1 row affected (0.14 sec)Display time from the table using select statement. The query is as follows −
mysql> select *from AverageOnTime;
The following is the output −
+-------------+ | PunchInTime | +-------------+ | 00:00:40 | | 00:02:50 | | 00:03:30 | | 00:04:55 | +-------------+ 4 rows in set (0.00 sec)
Now to get the average on time column, use the below query. The query is as follows −
mysql> SELECT SEC_TO_TIME(AVG(TIME_TO_SEC(PunchInTime))) as Average from AverageOnTime;
The following is the output displaying the average -
+---------------+ | Average | +---------------+ | 00:02:58.7500 | +---------------+ 1 row in set (0.08 sec)
