How to store time greater than 24 Hours in Mysql?

Question

I need to create a column (say idletime) that will store time value having hours smaller or bigger than 24. When i try to insert such values bigger than 24 (For example '80:00:00', '129:23:12', etc) , am getting the following error code:

java.sql.SQLException: Illegal hour value '80' for java.sql.Time type in value '80:00:00.
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:964)
.....

I have searched over the Internet and found that the TIME datatype ranges from 00:00:00 to 23:59:59 and does not reach 24:00:00.

Is there any solution available for my problem? Am executing this insert query within a stored procedure.

Answer 1

It seems that you have a problem from your sql client because of the nature of the exception "java.sql.SQLException".

• Go in in a bare console or another sqlclient and try to execute what you were trying to do

for example:

CREATE Table mytimetable (testtime TIME);

Insert into mytimetable values ('1:1:1'),('080:1:1'),('80:1:1');

select * from mytimetable ;
01:01:01
80:01:01
80:01:01

MySQL uses the 'HHH:MM:SS' format, which is larger than 24 hours. See doc for more

In MySQL, you can store 80:00:00 for time datatype.

CREATE TABLE `test_time` (
  `id` int(11) NOT NULL,
  `time` time DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

When getting the datetime with QUERY:

SELECT TIMESTAMP(`time`) FROM `test_time`

Output:

TIMESTAMP(`time`)    
---------------------
2018-04-22T08:00:00Z 

What i noticed is when storing in above format, it will +80 hours in stored time. for example:

if you stored the 80 hours what mysql do is set current time + your input. when you want to check what date and time it would be when adding 80:00:00 it will show above output, Also it can store max 838:59:59 hours.

I think I understand the use case, but I'm not sure I would elect to use the time datatype for the solution. It might as well be some sort of int datatype and named idle_time_in_seconds

You might also choose milliseconds if you need to be more exact.
