Better you try to check the condition before insert the data into DB if the PK value is already exists in DB then no need to insert otherwise it's inserted..

(or)

In DB itself you set the PK column as Auto increment column.

I told you in coding wise you do that stuff, your not an end user ... right..?, you know that logic , what are the PK column etc.. so, you do that stuff in your coding wise i'm also do the excel uploading concept, my table PK col is auto increment column . So, i never face this type of issue. But in some other page i'm facing this issue at that time i'm checking whatever i mentioned in my solution
