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.

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 third byte of the record, if there are no optional indicator bytes


  • Immediately after the last optional indicator byte

The length of the input data field, less any optional indicator bytes, is as specified in the first two bytes.
