17. Globalization and National Language Support (NLS)

Node-oracledb can use Oracle's National Language Support (NLS) to assist in globalizing applications.

Node-oracledb always uses Oracle's AL32UTF8 character set internally.
Data will be converted between AL32UTF8 and the database character set when it is inserted into, or queried from, the database. The environment variable NLS_LANG can be used to configure the Oracle client language and territory only.

Oracle NLS environment variables, or statements like ALTER SESSION, can be used to configure further aspects of node-oracledb data access globalization. Refer to NLS Documentation.
