Here is my query:
I have 2 files . first file has model code(A13) and n of the Spec codes (A5)( Max no of spec code 39) and second file has spec codes ( only 2 spec codes).
File 1 :
File 2 :
Here second file has spec1 spec2 and its needs to compared with file 1 and if there is any non matching record then it should be written in output.
Im aware of join keys but the problem is the file 1 spec code is dynamic and which leads to key parameters uncertain in Join keys.
Much appreciated your response in advance.
