Yulia, I did search but found a lot of confusingly similar information especially when the cases in grammar were concerned. That's why my question was asked directly in предложный case. Actually I wanted to distinguish them clearly.
Please, do not overestimate me just because of the words that I used, so that I can ask you questions one of which may be too simple or meaningless to you.
Thank you for the comment,
