Master Outer Join

Master Outer Join

A master outer join keeps all rows of data from the detail source and the matching rows from the master source. It discards the unmatched rows from the master source.
When you join the sample tables with a master outer join and the same condition, the result set includes the following data:
PART_ID
DESCRIPTION
SIZE
COLOR
1
Seat Cover
Large
Blue
3
Floor Mat
Medium
Black
4
Fuzzy Dice
NULL
Yellow
Because no size is specified for the Fuzzy Dice, the Integration Service populates the field with a NULL.
The following example shows the equivalent SQL statement:
SELECT * FROM PARTS_SIZE RIGHT OUTER JOIN PARTS_COLOR ON (PARTS_COLOR.PART_ID2 = PARTS_SIZE.PART_ID1)
