Hi Guys

I have a dw of 4 columns (The Key is A,B)

I imported it into my snap developer project and I Scaffolded it creating service and controller

The model is this  (for instance)

{ 

A: "",

B: "",

C: "",

D: ""

}

Now My CRUD API are created but I f I just want to update 2 columns of my dw

Now I call the create passing a complete Json:

{ 

A: "a",

B: "b",

C: "c",

D: "d"

}

If I call a Read the result is:

{ 

A: "a",

B: "b",

C: "c",

D: "d"

}

Now I just want to update properties A and B, my customer pass me just this on my WEB API:

{ 

A: "a",

B: "b",

C: "cc"

}

Is there a smart way to just update column C without set column D to null?

Or customer has to pass me the json containg all columns?

Thanks
