NLS_DATE_FORMAT
specifies the default date format to use with the TO_CHAR
and TO_DATE
functions. The default value of this parameter is determined by NLS_TERRITORY
.
The value of this parameter can be any valid date format mask, and the value must be surrounded by double quotation marks. For example:
NLS_DATE_FORMAT = "MM/DD/YYYY"
Note:
The value of this initialization parameter NLS_DATE_FORMAT
is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG
client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.
