Setting up the Globalization Support EnvironmentAdditional methods for setting the NLS parameters require that you shutdown andrestart the database. These techniques include the following:■See Also:■■"Setting NLS Parameters" in Oracle Database GlobalizationSupport Guide for details on setting the NLS parametersOracle Database SQL Reference for more information about SQLfunctions, including the TO_CHAR functionIncluding parameters in the Oracle Database initialization parameter file to specifythe default session NLS environment on the server side. For example:NLS_TERRITORY = "CZECH REPUBLIC"See Also: Oracle Database installation guide for Linux orWindows for information on setting globalization parameters andenvironmental variables.■Using NLS environment variables on the client, which may beplatform-dependent, to specify locale-dependent behavior for the client and alsoto override the default values set for the session in the initialization parameter file.For example, on a Linux system:% setenv NLS_SORT FRENCHSee Also: Oracle Database installation guide for Linux orWindows for information on setting globalization parameters andenvironmental variables.11.2.2 Choosing a Locale with the NLS_LANG Environment VariableA locale is a linguistic and cultural environment in which a system or program isrunning. Setting the NLS_LANG environment parameter is the simplest way to specifylocale behavior for Oracle software. It sets the language and territory used by the clientapplication and the database server. It also sets the client's character set, which is thecharacter set for data entered or displayed by a client program.The NLS_LANG parameter sets the language and territory environment used by boththe server session (for example, SQL command execution) and the client application(for example, display formatting in Oracle tools).You might want to modify the NLS environment dynamically during the session. Todo so, you can use the ALTER SESSION statement to change NLS_LANGUAGE, NLS_TERRITORY, and other NLS parameters.Note: You cannot modify the setting for the client character setwith the ALTER SESSION statement.The ALTER SESSION statement modifies only the session environment. The localclient NLS environment is not modified, unless the client explicitly retrieves the newsettings and modifies its local environment.11-4 SQL Developer Online Help
Setting up the Globalization Support EnvironmentSee Also:■■Oracle Database installation guides for information on theNLS_LANG environmental variableOracle Database SQL Reference for information on the ALTERSESSION statement.11.2.3 Language and Territory ParametersSetting different NLS parameters for local territories allows the database session to usedifferent cultural settings. For example, you can set the euro (EUR) as the primarycurrency and the Japanese yen (JPY) as the secondary currency for a given databasesession even when the territory is defined as AMERICA.This topic contains information about the following parameters:■ NLS_LANGUAGE■ NLS_TERRITORY11.2.3.1 NLS_LANGUAGEThe NLS_LANGUAGE parameter can be set to any valid language name and the defaultis derived from the NLS_LANG setting. NLS_LANGUAGE specifies the defaultconventions for the following session characteristics:■■■Language for server messagesLanguage for day and month names and their abbreviations (specified in the SQLfunctions TO_CHAR and TO_DATE)Symbols for equivalents of AM, PM, AD, and BC.■ Default sorting sequence for character data when ORDER BY is specified. (GROUPBY uses a binary sort unless ORDER BY is specified.)Example 11–1 and Example 11–2 show the results from setting NLS_LANGUAGE todifferent values. In Example 11–1, the ALTER SESSION statement is issued to set NLS_LANGUAGE to Italian.Example 11–1NLS_LANGUAGE=ITALIANALTER SESSION SET NLS_LANGUAGE=Italian;-- enter a SELECT to check the format of the output after the ALTER SESSIONSELECT last_name, hire_date, ROUND(salary/8,2) salary FROM employeesWHERE employee_id IN (111, 112, 113);You should see results similar to the following:LAST_NAME HIRE_DATE SALARY------------------------- --------- ----------Sciarra 30-SET-97 962.5Urman 07-MAR-98 975Popp 07-DIC-99 862.5Note that the month name abbreviations are in Italian.In Example 11–2, the ALTER SESSION statement is issued to change the language toGerman.Working in a Global Environment 11-5
