Release 10.1A: OpenEdge Development:
Progress 4GL Reference

> ## RELATION-FIELDS attribute

> Returns the list of join fields between the parent and child as specified in the data-relation object definition.

> Data type: CHARACTER

> Access: Readable

> Applies to: Data-relation object handle

> You can use the value of this attribute in writing code that uses or extends the list of join fields without having to parse the value of the WHERE-STRING attribute, which in the default case provides essentially the same information but not necessarily in an ideal form for analyzing the relation.
