Answer / vamse
not necessarily left outer join. Its inner join most of the time.
Loop up is generally used to fetch data for a particular filter condition.(matching critria should take a particular value from it.
Main table is usually large and look up table is small in ideal scenario.

Hi,
You can Say LookUp is a Left Outer join.Your Source Table is
Left side table and Lookup table is right table.
Now you are trying to get total source records and
matching records from lookup table(right table).
Hope this helpls....

Answer / ankit kansal
Lookup is used to check whether the row corresponding the incoming row is present or not and if yes then perform some logic and if not then do some other like we use to do it case of SCD2.
So, It is purely a left outer join where left table is your source table.
