What if I have a problem with encodings when using Oracle via ODBC?

· One min read

If you use Oracle as a source of ClickHouse external dictionaries via Oracle ODBC driver, you need to set the correct value for the NLS_LANG environment variable in /etc/default/clickhouse. For more information, see the Oracle NLS_LANG FAQ.

Example

NLS_LANG=RUSSIAN_RUSSIA.UTF8
