| Parameter type | String |
| Syntax | NLS_DATE_LANGUAGE = language |
| Default value | Derived from NLS_LANGUAGE |
| Modifiable | ALTER SESSION |
| Range of values | Any valid NLS_LANGUAGE value |
NLS_DATE_LANGUAGE specifies the language to use for the spelling of day and month names and date abbreviations (a.m., p.m., AD, BC) returned by the TO_DATE and TO_CHAR functions.
Note:
The value of this initialization parameterNLS_DATE_LANGUAGE 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.See Also:
