Dear Client,
I looked at the requirement and I assume that we have the given columns in a table since you have given skill required as SQL. If you can confirm me on data type of the fields Col A, Col B and Col C, I can get you query to achieve the result you are expecting.
Although, I don't have any reviews or rating, I can assure you of quality work since I have more than 6 years of experience in SQL.
I am reachable on Whats-app. My mobile number: +91 9619 510 609. Feel free to reach me anytime.
Looking forward to work with you.
Thanks & Regards,
Kunj Mishra
