How can I set a custom date time format in Oracle

Question

By default, Oracle SQL developer displays date values as 15-NOV-11. I would like to see the time part (hour/minute/second) by default.

Is there a way to configure this within Oracle SQL Developer?

Answer 1

Goto to Tools > Preferences. In the tree, select Database > NLS. There are three Date/Time formats available: Date, Timestamp and Timestamp TZ. Editing the Date format gives the desired effect.

Like I have said above; this approach has not given me a permanent change.

Answer 2

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

Answer 4

For anyone still having an issue with this; I happened to find this page from Google...

Put it in like this (NLS Parameters)... it sticks for me in SQLDeveloper v3.0.04:

DD-MON-YY HH12:MI:SS AM or for 24-Hour, DD-MON-YY HH24:MI:SS 

Answer 5

You can change this in preferences:

1. From Oracle SQL Developer's menu go to: Tools > Preferences.
2. From the Preferences dialog, select Database > NLS from the left panel.
3. From the list of NLS parameters, enter DD-MON-RR HH24:MI:SS into the Date Format field.
4. Save and close the dialog, done!

Answer 6

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.
