I read in one blog and posting here.
There are two categories of character sets in Teradata terminology:
Server Character Sets
Client Character Sets
Teradata is a truly multi-language database. That said, it has to have the ability to receive, process, store and return character data of all kinds. To that end, there come the two kinds of character sets. Server character sets are used for internal processing (like doing data retrieval or joining) and storage, while client character sets are used for converting incoming character data to the server character set (like issuing a query in BTEQ or SQL Assistant), and vice versa (like receiving result from BTEQ or exporting to an external file).
Server Character Sets
There are five supported server character sets:
LATIN
UNICODE
KANJISJIS
GRAPHIC
KANJI1 (deprecated)
The default server character set can be specified in the CREATE USER or MODIFY USER statement. If not specified, the server character set will by default be UNICODE for Japanese system and LATIN for all others.
CREATE USER dba1 AS PASSWORD=... PERM=... DEFAULT CHARACTER SET LATIN;
LATIN is mainly used by the ASCII client character set users. UNICODE is designed for storing ALL the characters in ALL languages in the world. KANJISJIS is a canonical character set for Japanese applications. GRAPHIC is designed for IBM DB2 compatibility.
Client Character Sets
There are more than 20 supported client character sets:
ASCII
EBCDIC
UTF8
UTF16
Japanese character sets
Chinese character sets
Korean character sets
Other single-byte international character sets
There's no limit on how many client character sets can be installed, but only 16 client character sets can be active at the same time. Only one client character set can be set as the default active character set, using the following BTEQ command:
.set session charset [CHARSET]
CHARSET can be one of the supported client character sets.
ASCII, EBCDIC, UTF8 and UTF16 are predefined and automatically supported for all configurations. In ASCII, each byte represents one character. It's the same for EBCDIC, while EBCDIC is only available for channel-attached clients. In UTF8, a character can consist of one to three bytes. In UTF16, each character is composed of two bytes.
