The following rules exist for Chinese and Korean character sets on both network and mainframe platforms. For information on Chinese and Korean character set restrictions, see Teradata Vantage™ - Advanced SQL Engine International Character Set Support, B035-1125.
SHOW TABLE Command
When you use the SHOW TABLE command, compress and default values that include any characters outside of 7-bit ASCII are shown as Unicode hexadecimal constants. Also, the SHOW TABLE command cannot show a table that has object names with characters outside of 7-bit ASCII.
Maximum String Length
The database requires two bytes to process each of the Chinese or Korean characters. This limits both request size and record size. For example, if a record consists of one string, the length of that string is limited to a maximum of 32,000 characters, or 64,000 bytes.
