Here are the default result type and attributes for LOWER(arg).

Data Type Heading
Same type as arg Lower(arg)

The LOWER function returns the result in the same character set as the input argument. The exception is when the input is KANJI1 data; LOWER returns the result in the LATIN server character set.

In accordance with Teradata internationalization plans, KANJI1 support is deprecated and is to be discontinued in the near future. KANJI1 is not allowed as a default character set; the system changes the KANJI1 default character set to the UNICODE character set. Creation of new KANJI1 objects is highly restricted. Although many KANJI1 queries and applications may continue to operate, sites using KANJI1 should convert to another character set as soon as possible. For more information, see KANJI1 Character Set in Teradata Vantageā„¢ - Advanced SQL Engine International Character Set Support, B035-1125.
