Subject wise display while setting 2 datasets

[ambadi007]

Hi Team,

I have 2 datasets First dataset name is Part1 and other is Part2..

in Part1 have some subjects and information and PArt2 has some other Subjects information

Now i need to set these 2 datasets using subject, and the condition is if Part1 and Part2 have same subjects then I need to display only the information from Part1 dataset while setting or merging 

Could you please help me on these

Can you provode some sample data?

parta; prtb
101 102
102 101
103 103

here the parta is the main dataset.. if i have parta and part b same subject (eg-103) i need to display only parta subjects information since this the initial data that is collected
