How can I set a custom date time format in Oracle SQL Developer?
In my case the format set in Preferences/Database/NLS was [Date Format] = RRRR-MM-DD HH24:MI:SSXFF but in grid there were seen 8probably default format RRRR/MM/DD (even without time) The format has changed after changing the setting [Date Format] to: RRRR-MM-DD HH24:MI:SS (without 'XFF' at the end).
There were no errors, but format with xff at the end didn't work.
Note: in polish notation RRRR means YYYY
I stumbled on this post while trying to change the display format for dates in sql-developer. Just wanted to add to this what I found out:
- To Change the default display format, I would use the steps provided by ousoo i.e Tools > Preferences > ...
But a lot of times, I just want to retain the DEFAULT_FORMAT while modifying the format only during a bunch of related queries. That's when I would change the format of the session with the following:
alter SESSION set NLS_DATE_FORMAT = 'my_required_date_format'
Eg:
alter SESSION set NLS_DATE_FORMAT = 'DD-MM-YYYY HH24:MI:SS'
With Oracle SQL Developer 3.2.20.09, i managed to set the custom format for the type DATE this way :
In : Tools > Preferences > Database > NLS
Or : Outils > Préférences > Base de donées > NLS
YYYY-MM-DD HH24:MI:SS
Note that the following format does not worked for me :
DD-MON-RR HH24:MI:SS
As a result, it keeps the default format, without any error.
You can change this in preferences:
- From Oracle SQL Developer's menu go to: Tools > Preferences.
- From the Preferences dialog, select Database > NLS from the left panel.
- From the list of NLS parameters, enter
DD-MON-RR HH24:MI:SS
into the Date Format field. - Save and close the dialog, done!
