- A variable-length indicator bytes field
- A variable-length input data field
The positions of the indicator bits correspond to the fields of the loading and exporting row. There is one bit for each column in the table. The first bit in the first byte is the indicator for the first field in the record. If an indicator bit is set to one, the database nulls the corresponding field when the record is loaded. If the indicator bit is set to zero, the database loads the data specified for that field.
For example, when there are less than 9 columns, there is a 1-byte indicator-byte length. Between 9 and 16 columns, there is a 2-byte indicator-byte length. There is a 3-byte indicator-byte length between 17 and 24 columns, etc.

When using the Teradata PT PutBuffer function with the Load driver, the input data can be in indicator mode or in non-indicator mode format. When using the PutBuffer function with the Update or Stream driver, the input data must be in indicator mode format.
