Thread: Table input Step

  1. #1

    Default Table input Step

    I am using table input step as the first step in my transformation. I am using a basic query to get all the rows(12000) form a table with only 1 column. Can I access this result set for the steps downstream? How does Table input step save these values? As an array ? and how do I access this result set?

    Each step in a transformation is a "row processor". The Table Input step, in your case, will send 12000 rows (with 1 column in each) to the downstream-connected step(s). Each downstream step (such as a Calculator step) can then do processing on each of those 12000 rows. Depending on the type of step you connect, the processing action can be different, i.e., grouping steps and statistics steps can do aggregations and produce fewer rows to their downstream-connected steps.
