Join Functions
The Join Function component joins two record-set sources. A common field from each originating source is used to connect the two sources.
At the most, the returned record-set object may contain the union of all the fields from both incoming record-set sources. At the least, the returned record-set object may contain as little as one field from either of the two incoming record-set sources.
The Join Function component returns a record-set object whose type whose type and format are determined by a previously defined Type Descriptor. If the Type Descriptor does not exist,
it must be created using the Type Descriptor Editor (described in the
IBM

Unica
Detect
Administration Guide
) before you can create a Select Function.
