Teradata supplies three multibyte character sets to support Korean on mainframe and network-attached clients.

Each character set uses a specific encoding form to distinguish single-byte characters from multibyte characters.

 

Character Set

Description

Encoding Form

HANGULEBCDIC933_1II

Korean (IBM CCSID 933) for mainframe clients.

EBCDIC Shift-Out/Shift-In.

Shift-out character 0x0E and shift-in character 0x0F bracket each string of double-byte characters.

HANGULKSC5601_2R4

Korean (mixed KSC5601) for network-attached clients.

Value of first byte in sequence distinguishes single-byte characters from double-byte characters.

HANGUL949_7R0

Korean (Windows Code Page 949) for network-attached clients.

Value of first byte in sequence distinguishes single-byte characters from double-byte characters.

To determine whether a Korean character is valid in a Teradata Database object name:

1 Find the text file on the documentation CD or on the Web at http://www.info.teradata.com/ that maps the character set to UNICODE.

2 In the text file, find the Unicode character to which the client character in question maps.

3 Find the file that identifies valid Unicode characters, UOBJNEXT.txt, available on the Teradata User Documentation CD and at http://www.info.teradata.com.

4 If the Unicode character appears in the file that is applicable to your system, you can use the client character that maps to it in an object name.

Note: Korean Object Names containing multibyte Hangul characters are currently not supported in Teradata Database under any client character set.

Character data entered using Korean client character sets should be stored in columns defined as Unicode. The UNICODE server character set requires two bytes of storage per character so that a CHAR(5) CHARACTER SET UNICODE field occupies 10 bytes of storage.

Given the 64000 byte limit on column size, a column cannot exceed 32000 characters. Furthermore, the combination of character data and other data types cannot exceed the 64000 byte limit on row size.
