What is a diff between joiner and lookup transformation
Answer Posted / gopal
In joiner we can join two heterogeneous sources for entire
records based on a condition.
But in look up only the first value or last value of the
records will be passed if more records matched with that
condition. So only one value will be returned to the
transformation.
EX:
in source : No Name
1 -
Look up table: No Name
1 A
1 B
1 C
Now we can return only A or C in look up.
If we need entire values we must go for joiner. Take that
look up table as source and use joiner. No alternative
solution.
