Get the time difference and convert it to hours in MySQL?
You can achieve with the help of timestampdiff() method from MySQL. The syntax is as follows −
Syntax
SELECT ABS(TIMESTAMPDIFF(HOUR,yourColumnName1,yourColumnName2)) as anyVariableName from yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table DifferenceInHours -> ( -> StartDateTime datetime, -> EndDateTime datetime -> ); Query OK, 0 rows affected (0.59 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into DifferenceInHours values('2018-12-20 10:00:00', '2018-12-19 12:00:00');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DifferenceInHours values('2018-12-20 11:00:00', '2018-12-19 11:00:00');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DifferenceInHours values('2018-12-20 10:30:00', '2018-12-19 11:00:00');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement. The query is as follows −
mysql> select *from DifferenceInHours;
Output
+---------------------+---------------------+ | StartDateTime | EndDateTime | +---------------------+---------------------+ | 2018-12-20 10:00:00 | 2018-12-19 12:00:00 | | 2018-12-20 11:00:00 | 2018-12-19 11:00:00 | | 2018-12-20 10:30:00 | 2018-12-19 11:00:00 | +---------------------+---------------------+ 3 rows in set (0.00 sec)
Here is the query that gets time difference in hours. The query is as follows −
mysql> SELECT ABS(TIMESTAMPDIFF(HOUR,StartDateTime,EndDateTime)) as Hour from DifferenceInHours;
The following is the output displaying the time difference in hours −
+------+ | Hour | +------+ | 22 | | 24 | | 23 | +------+ 3 rows in set (0.00 sec)
