In the executable section of the script, APPLY statements specify all operations to be performed by the job and the objects that will perform them. For detailed information on APPLY, see Teradata Parallel Transporter Reference (B035-2436).

Processing statement specifications include the following:

  • APPLY...TO to specify:
    • the operators that will be used to load or update the data
    • the number of instances to be used for the operators
    • operator attribute values (optional)
  • SELECT...FROM to specify:
    • the operators that will be used to acquire, and if necessary, filter the data
    • the number of instances to be used for the operator
    • the selected columns to be sent to the consumer operator
    • operator attribute values (optional)
  • WHERE clauses, CASE DML or CASE value expressions, and SELECT derived column values to filter data between source and destination. See Data Filtering and Conditioning Options.

Set the degree of processing parallelism to be used for each operator. See Optimizing Job Performance with Sessions and Instances.
