Sysdate does not display correctly in Toad for Oracle after changing NLS_CALENDAR parameter (4329013)

The sysdate (select sysdate from dual) does not display correctly in Toad for Oracle after changing NLS_CALENDAR parameter.

1. In SQLPlus, run

ALTER SESSION SET NLS_CALENDAR=PERSIAN
SELECT SYSDATE FROM DUAL

13 Esfand 1387

This is the expected result.

2. In the Editor on Toad for Oracle, run

ALTER SESSION SET NLS_CALENDAR=PERSIAN
SELECT SYSDATE FROM DUAL

03.03.2009 3:13:11 PM

This is not the expected result.

WORKAROUND #1:
Use this SQL statement instead "select to_char(sysdate,'dd-month-yyyy') from dual"

WORKAROUND #2:
Use F5 or Execute as Script command

STATUS:
Waiting for a fix in a future release of Toad for Oracle.
