This table describes the data limits on INSERT operations for various CHARACTER and GRAPHIC server character sets.
| Client Character Set Type | USING Data Type | Maximum Size for USING Data | Server Character Set | Maximum Column Size for INSERT (Characters) |
|---|---|---|---|---|
| Single byte | CHARACTER | 64,000 bytes | LATIN | 64,000 |
| KANJI1 | ||||
| UNICODE If the USING data row contains more than 32K logical characters (or more than 64K bytes when mixed single-byte-multibyte strings are involved), the characters that exceed that limit are truncated. Note that this includes Unicode data in both UTF-8 and UTF-16 sessions. |
32,000 | |||
| KANJISJIS If the USING data row contains more than 32K logical characters (or more than 64K bytes when mixed single-byte-multibyte strings are involved), the characters that exceed that limit are truncated. |
||||
| Multibyte | CHARACTER | 64,000 bytes | LATIN If the USING data row contains more than 32K logical characters (or more than 64K bytes when mixed single-byte-multibyte strings are involved), the system rejects the row. Although a Latin field can be defined as 64K, you cannot insert more than 32K multibyte characters into it because Teradata Database uses Unicode internally, and Unicode has a 32K limit. The load utilities are similarly limited. |
