Conversion of character data type between a client form-of-use and the Teradata Database form-of-use may encounter exception situations.
There are three possible exceptions.
| Type | Description | See |
|---|---|---|
| Illegal client data form-of-use | An illegal form-of-use occurs when the client data violates the structure of the client form-of-use, for example, an unmatched SI character in KanjiEBCDIC. | Illegal Form-of-Use |
| Conversion exception | A conversion exception occurs when there is no character in the target repertoire that corresponds to a character from the source string. | |
| Truncation exception | A truncation exception occurs when the source cannot fit into the target field without truncation of a non-pad character. | Truncation Exceptions |
