The Enrichment activity allows four links:
In the fourth option (a link):
Link definition: Allows the selection of the type of link and the target of the link. Link type includes:
- Define a collection (1-N relationship)
- Define a link whose target is always available (1-1 relationship). The join conditions must be defined by a single record in the target table.
- Define a link whose target may not exist in the database (0-1 relationship).
- Define a link by searching for a reference among several options (1-1 or 1-N relationship).
Question:
Does each link definition establish a SQL right join from the filtering dimension (table) to the target table?
Or, does it establish a SQL right join except the third option:
"3. Define a link whose target may not exist in the database (0-1 relationship)). The join condition must be defined by 0 or 1 (max.) record in the target table."
...which sounds like it establishes a left join.
Thanks.
