1.210 NLS_LANGUAGE

NLS_LANGUAGE specifies the default language of the database.

Property Description

Parameter type

String

Syntax

NLS_LANGUAGE = language

Default value

Operating system-dependent, derived from the NLS_LANG environment variable

Modifiable

ALTER SESSION

Modifiable in a PDB

Yes

Range of values

Any valid language name

Basic

Yes

This language specified by NLS_LANGUAGE is used for messages, day and month names, symbols for AD, BC, a.m., and p.m., and the default sorting mechanism. This parameter also determines the default values of the parameters NLS_DATE_LANGUAGE and NLS_SORT.

Note:

The value of this initialization parameter NLS_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.
