In this scenario, you create a Job using tTeradataTPump to insert customer data into a Teradata database table and specify the exit code to be displayed in the event of an exception error.

Three components are used in this Job:

  • tRowGenerator: generates rows as required using random customer data taken from a list.

  • tFileOutputDelimited: outputs the customer data into a delimited file.

  • tTeradataTPump: inserts the customer data into the Teradata database table in the Tpump mode.

Dropping components

  1. Drop the required components: tRowGenerator, tFileOutputDelimited and tTeradataTPump from the Palette onto the design workspace.

  2. Link tRowGenerator to tFileOutputDelimited using a Row > Main connection.

  3. Link tRowGenerator to tTeradataTPump using a Trigger > On SubjobOk connection.

Configuring the components

  1. Double click tRowGenerator to open the [tRowGenerator Editor] window.

    In the [tRowGenerator Editor] window, define the data to be generated. For this Job, the schema is composed of two columns: ID and Name.

    Enter the Number of Rows for RowGenerator to generate.

  2. Double click tFileOutputDelimited to define its properties in the Component view.

  3. Next to File Name, browse to the output file or enter a name for the output file to be created.

  4. Between double quotation marks, enter the delimiters to be used next to Row Separator and Field Separator.

    Click Edit schema and check that the schema matches the input schema. If need be, click Sync Columns.
