Using Expression transformation how to remove duplicate
records from a relational source?
Answer Posted / prathibha
Hi,
Source->SQ->Sorter->Expression->FilterTarget.
Lets take a small example for this scenario.
Use a sorter to sort the input data.
ID Name
1 A
1 A
2 B
3 C
3 C
In Expression Transformation declare the following ports:
ID
Name
O_Count= iiF(V_port=ID,O_Count=O_count+1,O_Count=0)
V_port(Variable Port) = ID;
In filter transformation give the condition O_Count =0;
Let me know if there are any suggestions.
