I have an excel sheet with multiple ID's in a column. Now i need fetch those ID's in an application and check whether if it already exist in the DB. If not then i have to go with the process of inserting them in the DB. If it exists then i need to skip that ID and move to the next ID and check the same and proceed. How can i do that with for loop and if condition?
