Custom date time format in Oracle SQL Developer?
 
01:03
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 or for 24-Hour, DD-MON-YY HH24:MI:SS Or just for an active session use below instead. alter SESSION set NLS_DATE_FORMAT = 'required_date_format' i.e. alter SESSION set NLS_DATE_FORMAT = 'DD-MM-YYYY HH24:MI:SS' into the Date Format field. Save and close the dialog.

Oracle CURRENT_TIMESTAMP Function
 
02:37
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_TIMESTAMP function will display the current date and time in the session time zone. Just like the CURRENT_DATE function, it uses the session time zone, which is where you logged in from. This could be different to the database time zone. The syntax of the CURRENT_TIMESTAMP function is: CURRENT_TIMESTAMP ( [precision] ) The return type of this function is TIMESTAMP WITH TIME ZONE. The precision parameter is optional, and it lets you specify the number of fractional seconds to return. If this is omitted, it uses the default of 6. It’s different to the SYSTIMESTAMP function, because CURRENT_TIMESTAMP returns the session timezone, and SYSTIMESTAMP returns the database time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_TIMESTAMP will return a date and time that’s 10 hours ahead of SYSTIMESTAMP, and in a different time zone. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_TIMESTAMP - 7 for 7 days ago). However, it might be better to use interval data types so you can keep the original data type.

Oracle FROM_TZ Function
 
01:45
https://www.databasestar.com/oracle-timezone-functions/ The Oracle FROM_TZ function is used to convert a value in a TIMESTAMP data type, and a specific TIME ZONE, to a TIMESTAMP WITH TIME ZONE value. It’s a helpful conversion function if you work with times and time zones a lot. The syntax of the FROM_TZ function is: FROM_TZ ( timestamp_value, timezone_value ) The parameters of this function are: - timestamp_value: the value in a TIMESTAMP format to convert. - timezone_value: this is the timezone value that the timestamp_value will be converted in to. If you want to know what values can be used as a timezone value, you can look in the database view here: SELECT * FROM v$timezone_names; For more information about the Oracle FROM_TZ function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-timezone-functions/
