This will happen if you haven't loaded the time zone table into mysql.
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
mysql
is the name of the built-in database that holds MySQL-specific configuration data.
I found this thread after spending some time trying to figure out why after running the command in the accepted answer (which is the same on MySQL's dev site) the command was unable to convert between timezones such as
SELECT CONVERT_TZ('2004-01-01 12:00:00','UTC','MET') AS time
It turns out that on OS X there are two files that cause problems: /usr/share/zoneinfo/Factory
and /usr/share/zoneinfo/+VERSION
.
The fix... temporarily moving these files to a different location such as /usr/share/zoneinfo/.bak/
allows for the command
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
to fully populate all of the expected timezone information.
This may or may not be a bug in my installed version of MySQL:
$ mysql --version
mysql Ver 14.14 Distrib 5.6.11, for osx10.6 (x86_64) using EditLine wrapper
I am also operating in STRICT_MODE
.
In any case, I hope this saves a few headaches for anyone searching for the fix.
Apart from Windows environment, You can set Time Zone by
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
In Windows environment,
1. download Time zone description tables from
http://dev.mysql.com/downloads/timezones.html
2. Stop MySQL server
3. Put then inside Mysql installation package
(ie. C:\Program Files\MySQL\data\mysql)`
4. Start MySQL server
..Your work is finished..
If still you are getting NULL
for CONVERT_TZ
Download these database tables and insert it into mysql database http://www.4shared.com/folder/Toba2qu-/Mysql_timezone.html
Now you problem will be solved.. :)
MAMP PRO
Terminal
cd /usr/share/zoneinfo/
sudo mv +VERSION ~/Desktop
cd /applications/MAMP/Library/bin
sudo ./mysql_tzinfo_to_sql /usr/share/zoneinfo | ./mysql -p -u root mysql
sudo mv ~/Desktop/+VERSION /usr/share/zoneinfo/
1) In Windows, there isn't any data folder now in C:\Program Files\MySQL\
as in other answers.
2) In that case, look for C:\ProgramData\MySQL\MySQL Server 5.x\Data\mysql
. Generally this folder hidden and you will not see C:\ProgramData\
some times.
3) Change the Settings in View tab to see Hidden files and Folders as explained here https://irch.info/index.php?pg=kb.page&id=133
4) Stop the MySQL service by searching for "services" in Windows Start button.
5) Then unzip the timezone_2017c_posix.zip and then copy the files in it (copy the files directly, don't copy the whole folder itself), and paste in
C:\ProgramData\MySQL\MySQLServer5.x\Data\mysql\
6) For MySQL 5.7, timezone_2017c_posix.zip will just give a .sql file after unzipping and it may not solve the issue. So go ahead and download the zip file for 5.6 even if you are running MySQL 5.7 and copy those files to C:\ProgramData\MySQL\MySQL Server 5.x\Data\mysql\
7) Restart the MySQL server. To check if the CONVERT_TZ () is working, run this sql query.
SELECT CONVERT_TZ('2004-01-01 12:00:00','UTC','Asia/Jakarta');
and check for non-null output.
These are the steps to make it work if you're in windows and using MySQL 5.7.
mysql -u root -p password
.use mysql
to select the MySQL DB.On successful completion, you should be able to use CONVERT_TZ
and other timezone functions.
