Join Type
Normal Join
A
normal join will allow only those records which satisfy the joiner condition for both sources. So remaining records, who don’t match the condition get discarded
Master Outer Join
A
master outer join will keeps all rows of data from the detail source and the matching rows from the master source. If any of master records don’t satisfy the condition , those rows get discarded.
Detail Outer Join
Just opposite to
Master Outer join , it keep all rows of data from Master Source and the matching rows from Details Source. If any of detail records don’t satisfy the condition , those rows get discarded.
Full Outer Join
A
full outer join keeps all rows of data from both the master and detail sources.
