OUTER JOIN Predicate

An outer join predicate specifies two tables and returns a result table that contains all the rows from one of the tables, even if there is no matching row in the other table. See the "Outer Joins" section for more information.

This is the syntax for an outer_join_predicate:

SYNTAX
[ table_name.]column = [ table_name.]column (+)
  | [ table_name.]column (+) = [ table_name.]column
