The internal format of each output record must conform to the specified schema.

The FastExport OUTMOD Adapter operator requires each field of the output record to be of a specified length. When no length is specified, the operator assumes the conventional default length.

The FastExport OUTMOD Adapter operator supports both fixed- and variable-length output records.

For records with a two-column schema such as:

(
  COL1 INTEGER,
  COL2 VARCHAR(10));
each record comprises:
  • A four-byte integer, because 4 is the INTEGER length
  • A two-byte length indicator for the VARCHAR field
  • The CHAR data of the length indicated in the two-byte length indicator field
The following examples show the byte order when running Teradata PT on an Intel processor.
  • If, for example, the integer has a decimal value of 100 and the VARCHAR is ASCII '12345', then the output record appears in hexadecimal notation as:
    X'64 00 00 00 05 00 31 32 33 34 35'
  • If the data in the output record is in indicator mode, there is a single preceding indicator byte:
    X'00 64 00 00 00 05 00 31 32 33 34 35'
