public class LookupComponent
extends JoinComponent

The lookup component is a mapping component with specialized join functionality, allowing the lookup of columns from a lookup table. It is functionally equivalent to a left outer join. The driving table becomes the left side of the left outer join, so all records of the driving table will participate in the join. The lookup may be generated as either a left outer join or a correlated sub query.

Since:

12.1.2.0.0

static class	LookupComponent.NO_MATCH_ROWS The NO_MATCH_ROWS enumeration specifies the behavior when no matching rows are found in the lookup table.
