I have a scenario below:
I have a table with 4 columns: student_name,maths_marks,physics_marks,chemistry_marks
I am using the adapter select service to get the records from the table.
The result of all the marks column are objects (not strings).
Now the output which is expected is
student_name : total_marks(sum of marks columns).
Can someone help me how this can be done.(I want only flowservice without javaservice).This should be done through best practices.
