There is a scenario I am trying to achieve. I want to query the same list to check whether the combination value exists or not in the form. There are 2 columns Name and ID. In the form when anyone enters the name and id value I want to check whether there is a item with entered name and id. If yes I would display a label. How can I achieve it in the form?

you can find possible approach eg. here  

note however you can not reliably prevent adding two items with the same key values if they are both being added at about same time.
