"SELECT * FROM Rest_Category
                INNER JOIN Rest_Details
                ON Rest_Category.CategoryID = Rest_Details.Cat_ID
                INNER JOIN Delivery_Pcode
                ON Delivery_Pcode.Restaurant_ID = Rest_Details.Resturant_ID
                WHERE Delivery_Pcode.Pcode= '$searchq'";

nebo (před řádnou dezinfekcí vstupu)

  "SELECT * FROM Rest_Category
                INNER JOIN Rest_Details
                ON Rest_Category.CategoryID = Rest_Details.Cat_ID
                INNER JOIN Delivery_Pcode
                ON Delivery_Pcode.Restaurant_ID = Rest_Details.Resturant_ID
                WHERE Delivery_Pcode.Pcode= '" . $searchq ."';";
