The binary data format is a 2-byte integer, n, followed by n bytes of data. Binary data format is similar to formatted data format, except that there is no end-of-record marker.
Each record has:
- A two-byte data length field
- Optionally, a variable-length indicator bytes field
- A variable-length input data field
The following table lists the unformatted binary record field descriptions.
| Input Record Field | Description |
|---|---|
| Data length | A two-byte field indicating the total length of the record, in bytes, excluding the first two bytes (this field) The data length must be specified as an explicit value, not an ASCII value. For a data length of one byte, for example, the specification must be hexadecimal 01. It cannot be hexadecimal 31, or the ASCII equivalent of the number 1. |
| Indicator bytes | Optional bytes to indicate null data |
| Input data | The actual input data for rows in the Teradata FastLoad table. The input data stream always starts at either:
The length of the input data field, less any optional indicator bytes, is as specified in the first two bytes. |
