Left Outer Join Showplan Operator
The Left Outer Join operator returns each row that satisfies the join of the first (top) input with the second (bottom) input. It also returns any rows from the first input that had no matching rows in the second input. The nonmatching rows in the second input are returned as null values. If no join predicate exists in the Argument column, each row is a matching row.
Left Outer Join is a logical operator.
