how avoid dublicate data to mysql

Question

I write the code to scrap car info(title, make, model, transmission, year, price) data from ebay.com and save in the mysql, I want if all row\'s(title, make, model, ...) item\'s

Answer 1

You could save the result of this query into a variable

SELECT COUNT(*) FROM car_info WHERE Title = , Maker = , Model = , Transmission = , Year = , Price = 

and then, if the value of the variable is

• 1, you skip the INSERT because you already have this entry in the table
• 0, you make the INSERT because you do not have that entry in the table

It's just one way of doing this.
