From SQ pass to Expression Transformation
- Take Variable for ID i.e.
V_ID =iif(not isnull(ID),ID ,V_ID )
- Take Variable for Name i.e.
iif( isnull(ID) ,CONCAT(CONCAT(LTRIM(RTRIM
(V_old_Name)),' ') ,Name),Name)
At this stage you will see the Data like this
ID Name
101 PANKAJ
101 PANKAL KUMAR
101 PANKAJ KUMAR MATHUR
Now pass the ID and NAME output port through an Aggregator
Transformation
-Take new variable for Name i.e.
New_Name=concat(concat(New_Name,' '),Name)
-Take new output port for Name and put expression for the
Name output port as follows
Out_Name=GREATEST(Name,New_Name)
- Check Group By on ID
Pass the ID and Name outpurt port to the Target.
option (truncate and load)
Where Group by on ID port
