Question/Problem Description
How to alter the date format when the application date parameters do not match the format of the Oracle database.
Steps to Reproduce
Clarifying Information
An application may have a date parameter specified as DD/MM/YYYY. The default Oracle date format is YYYY/MM/DD. The application session with the database can be changed to allow date parameters to be entered in the database without error or data corruption.
Error Message
Defect Number
Enhancement Number
Cause
Resolution
To determine how the date format is configured on the Oracle database run:

SELECT value FROM nls_session_parameters WHERE parameter = 'NLS_DATE_FORMAT'

If date parameters in the application are specified in a different format, the application session with the database can be changed. In the application set the NLS_DATE_FORMAT format to match the application parameters.
Use the following statement to set the desired date format.
ALTER SESSION SET nls_date_format = '<desired_format'

For example:
ALTER SESSION SET nls_date_format = 'dd/mm/yyyy'
