asp+access注入 數據庫 （access數據庫沒有數據庫名） 表名 字段(列名) 記錄(行,內容) 注入常用函數： top n 表示查詢結果的第n個記錄 len() 函數返回文本字段中值的長度 mid(column_name,start[,length])函數用於從文本字段中提取指定長度的字符 asc() 返回指定文本字符的ASCII碼 ORDER BY 語句用於根據指定的列對結果集進行排序。默認按照升序對記錄進行排序，降序使用 DESC 關鍵字。order by admin DESC 一、asp+access 手工注入聯合查詢法 http://127.0.0.1/0/Production/PRODUCT_DETAIL.asp?id=1513 and 1=1
