I have an automotive e-commerce website. I use the sql code to retrieve data from the server to my cars model page like dealers price in various cities or the on-road price of a particular car in selected city. But from few days, in one of my car model page is not retrieving information from database and i have shown this issue to my technical person. He is stuck in the middle of solving issue. I want to know how can I solve it. So, that I can suggest it to my tech person.
Thank in advance
