Producer Operators
The Teradata PT producer operators in this section read data from an external data source and place it in the data stream.
The Teradata PT job script invokes a producer operator using a SELECT statement within an APPLY statement. For further information on using SELECT to specify a producer operator, see “Coding the APPLY Statement” on page 64 and the section on APPLY in Teradata Parallel Transporter Reference.
The following table briefly describes and compares the function of each Teradata PT operator that can be used as a producer when moving data from an external source into Teradata Database:
