Creating a Joiner transformation

Creating a Joiner transformation

Use a Joiner transformation to join data from two related heterogenous sources.
Before you create a Joiner transformation, add Source transformations to the mapping to represent source data. Include any other upstream transformations that you want to use.
If the data in the two pipelines include matching field names, rename one set of fields in a transformation upstream from the Joiner transformation.
  1. In the
    Transformation palette
    , drag a Joiner transformation onto the mapping canvas.
  2. Connect an upstream transformation that represents one data set to the Master group of the Joiner transformation.
    To improve job performance, use the transformation that represents the smaller data set.
  3. Connect an upstream transformation that represents the other data set to the Detail group of the Joiner transformation.
  4. On the
    General
    tab, enter a name and optional description for the transformation.
  5. On the
    Incoming Fields
    tab, configure the field rules that define the data that enters the transformation.
  6. On the
    Field Mappings
    tab, select the
    Join Type
    .
  7. To create a join condition, the
    Join Condition
    , select Simple to create join conditions.
  8. Click
    Add New Join Condition
    , and then select the master and detail fields to use.
    You can create multiple join conditions.
You can add downstream transformations to the mapping and configure them. When the mapping is complete, you can validate and save the mapping.
