Now, I need to take the absolute of the amount and then I need to sum it up. The total number of records will be around 7 million.

Kindly help me with a code to fulfill the above requirement.

I have supplied code that meets all of your requirements. You claim that my code doesn't work but have given absolutely no evidence that it does not work.

Please create a small database (with a dozen records instead of 7 million records) and show us the actual values in ALL of the records, the results produced by my code, and the results produced by your database. Without data that we can verify, there is nothing more we can do for you.
