Answer / swetha
yoU can join hetrogenious data sources in joiner
transformation which we can not achieve in source qualifier
transformation. yoU need matching keys to join two
relational sources in source qualifier transformation. Where
as you doesn't need matching keys to join two sources. Two
relational sources should come from same datasource in
source qualifier. yoU can join relatinal sources which aer
coming from different sources also.

Answer / david
One important thing is
IN source Qualifier 1)the columns used in the condition must
have primary-key and foreign-key relationship(Compulsory)
For example
If the condition is
Emp.deptno = dept.deptno1
The depeno and deptno1 should have primary and foreign
key relation
2)The datatypes of the couumns must be same
