Please create a mapping where I have source which has one column with name like Aman_Gupta
Rakesh_Mehra
Sachin_More
I want the target field should contain the name in reverse order i.e Gupta_Aman

Can you please tell me what transformation would be needed to do this.

name1:select substr(name,1,instr(name,'_',1,1)-1)
