Comparing SQL Data Results with CSV file contents

Apr 3 2015 9:24 AM
I have the following scenario that I need to resolve and I'm unsure of how to approach it. Let me explain what I am needing and what I have currently done.
 
I've created an application that automatically marks assessments that delegates complete by comparing SQL Data to CSV file data. I'm using C# to build the objects required that will load the data from SQL into a dataset which is then compared to the associated CSV file that contains the required results to mark against.
 
Currently everything is working as expected but I've noticed that if there is a difference in the number of rows returned into the SQL-based dataset, then my application doesn't mark the items at all.
 
Here is an example:
 
ScenarioCSV contains 4 rows with 8 columns of information, however, let's say that the delegate was only able to insert 2 rows of data into the dataset. When this happens it marks everything wrong because row 1 in both CSV and dataset files were correct, however, row 2 in the dataset holds the results found in row 4 in the CSV file and because of this it is comparing it against row 2 in the CSV file.
 
How can I check whether a row, regardless of its order, can be marked as it does exist but not in the same order, so I don't want the delegate to lose marks just because the row data in the dataset is not perfectly in the same order of the row data in the CSV file???
 
I'm at a loss and any assistance will be of huge help to me. I have implemented a ORDER BY clause in the dataset and ensured that the same order is set in the CSV file. This has helped me for scenarios where there are the right number of rows in the dataset, but as soon as there is 1 row that is missing in the dataset, then the marking just doesn't allow for any marks for both rows even if the data is correct.
 
I hope I've made sense!! If not, let me know and I will provide a better description and perhaps examples of the dataset data and the csv data that is being compared.
 
Thanks in advance....
