The internal format of each input record intended for use with the MultiLoad INMOD Adapter operator must conform to the specified schema.

The MultiLoad INMOD Adapter operator requires each field to be of a specified length. When no length is specified, the operator assumes the conventional default length.

The MultiLoad INMOD Adapter operator supports both fixed- and variable-length input records.

For records with a two-column schema such as:

(
  COL1 INTEGER,
  COL2 VARCHAR(10));

each record is comprised of:

  • A four-byte integer, because 4 is the INTEGER length,
  • A two-byte length indicator for the VARCHAR field, and
  • 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 input record appears in hexadecimal notation as:
    X'64 00 00 00 05 00 31 32 33 34 35'
  • If the data in the input record is in indicator mode, a single precedes the indicator byte:
    X'00 64 00 00 00 05 00 31 32 33 34 35'
