How to set default value for datetime column in MYSQL?

Question

I have a web app, that logging some events (not important what). My web server is in different timezone , i want to log date and time of my timezone.

I created simple DB table with fields: ID - BIGINT (auto increment), primary key WH - DATETIME (this is the problematic one) LOG_TEXT VARCHAR(255) (text of event)

field WH is the problematic, i can set only CURRENT_TIMESTAMP, but showing 6 hours less than my current timezone time.

So i tried to set up default value for field WH (in phpMyAdmin) , with the following: CONVERT_TZ(WH,@@global.time_zone,'+01:00')

phpMyAdmin shows me the following error:

#1067 - invalid default value for 'WH'

any help how to set up different timezone for CURRENT_TIMESTAMP ?

PS: I googled a lot, no answer that matches for that question PPS: I cannot change timezone on my server, it's a shared hosting and it's simply not possible.

thanks in advance for your valuable comments.

Answer 1

So , this is the way i solved my problem:

• Created a view with the same fields, but field WH was incremented by 6hours. I know it's not the best option,but all of my stuff is being processed in the same timezone (UTC+6)

Now correct timestamp data is stored in this view, however the original LOG table has system timezone timestamp. Field WHin table LOG has default value CURRENT_TIMESTAMP

Now i can view my logs by selecting values from V_LOG .

SQL:

CREATE ALGORITHM=UNDEFINED DEFINER=`myuser`@`localhost` SQL SECURITY DEFINER VIEW `V_LOG` 
AS 
SELECT ID, DATE_ADD(WH,interval 6 HOUR) AS WH,LOG_TEXT FROM LOG;

I was unable to use CONVERT_TZ with @@global.time_zone, because views cannot contain parameters.
