节点代码来显示所有产品。所以我需要更改数据库结构或修改我的代码？

module.exports.list = (icondir, callback) => {
    conn.query(`SELECT productId,productCode,categoryId,subCategoryId,productName,productImg,mrp,sellingPrice,variant,percentageOff,isTopSelling,isAvailable,productFeatures,productDescription FROM tbl_products where isDeleted=0`, (err, row) => {
        if (err) {
            callback(err, null);
        } else {
            callback(null, row);
        }
    });
}
