不好意思 在自己的編譯環(huán)境中 是取的login2.js 這個(gè)名字
發(fā)帖時(shí) 自己 在貼 login2.js 里的內(nèi)容 時(shí) 直接取了個(gè)名字叫l(wèi)ogin.js了

SQL經(jīng)典面試題及答案2007年07月27日 星期五 上午 08:421.一道SQL語(yǔ)句面試題，關(guān)于group by
表內(nèi)容：
2005-05-09 勝
2005-05-09 勝
2005-05-09 負(fù)
2005-05-09 負(fù)
2005-05-10 勝
2005-05-10 負(fù)
2005-05-10 負(fù)

如果要生成下列結(jié)果, 該如何寫(xiě)sql語(yǔ)句?

勝 負(fù)
2005-05-09 2 2
2005-05-10 1 2
------------------------------------------
create table #tmp(rq varchar(10),shengfu nchar(1))

insert into #tmp values('2005-05-09','勝')
insert into #tmp values('2005-05-09','勝')
insert into #tmp values('2005-05-09','負(fù)')
insert into #tmp values('2005-05-09','負(fù)')
insert into #tmp values('2005-05-10','勝')
insert into #tmp values('2005-05-10','負(fù)')
insert into #tmp values('2005-05-10','負(fù)')

1)select rq, sum(case when shengfu='勝' then 1 else 0 end)'勝',sum(case when shengfu='負(fù)' then 1 else 0 end)'負(fù)' from #tmp group by rq
2) select N.rq,N.勝,M.負(fù) from (
select rq,勝=count(*) from #tmp where shengfu='勝'group by rq)N inner join
(select rq,負(fù)=count(*) from #tmp where shengfu='負(fù)'group by rq)M on N.rq=M.rq
3)select a.col001,a.a1 勝,b.b1 負(fù) from
(select col001,count(col001) a1 from temp1 where col002='勝' group by col001) a,
(select col001,count(col001) b1 from temp1 where col002='負(fù)' group by col001) b
where a.col001=b.col001

2.請(qǐng)教一個(gè)面試中遇到的SQL語(yǔ)句的查詢(xún)問(wèn)題
表中有A B C三列,用SQL語(yǔ)句實(shí)現(xiàn)：當(dāng)A列大于B列時(shí)選擇A列否則選擇B列，當(dāng)B列大于C列時(shí)選擇B列否則選擇C列。
------------------------------------------
select (case when a>b then a else b end ),
(case when b>c then b esle c end)
from table_name

3.面試題：一個(gè)日期判斷的sql語(yǔ)句？
請(qǐng)取出tb_send表中日期(SendTime字段)為當(dāng)天的所有記錄?(SendTime字段為datetime型，包含日期與時(shí)間)
------------------------------------------
select * from tb where datediff(dd,SendTime,getdate())=0

4.有一張表，里面有3個(gè)字段：語(yǔ)文，數(shù)學(xué)，英語(yǔ)。其中有3條記錄分別表示語(yǔ)文70分，數(shù)學(xué)80分，英語(yǔ)58分，請(qǐng)用一條sql語(yǔ)句查詢(xún)出這三條記錄并按以下條件顯示出來(lái)（并寫(xiě)出您的思路）：
大于或等于80表示優(yōu)秀，大于或等于60表示及格，小于60分表示不及格。
顯示格式：
語(yǔ)文 數(shù)學(xué) 英語(yǔ)
及格 優(yōu)秀 不及格
------------------------------------------
select
(case when 語(yǔ)文>=80 then '優(yōu)秀'
when 語(yǔ)文>=60 then '及格'
else '不及格') as 語(yǔ)文,
(case when 數(shù)學(xué)>=80 then '優(yōu)秀'
when 數(shù)學(xué)>=60 then '及格'
else '不及格') as 數(shù)學(xué),
(case when 英語(yǔ)>=80 then '優(yōu)秀'
when 英語(yǔ)>=60 then '及格'
else '不及格') as 英語(yǔ),
from table

5.在sqlserver2000中請(qǐng)用sql創(chuàng)建一張用戶(hù)臨時(shí)表和系統(tǒng)臨時(shí)表，里面包含兩個(gè)字段ID和IDValues,類(lèi)型都是int型，并解釋下兩者的區(qū)別?
------------------------------------------
用戶(hù)臨時(shí)表:create table #xx(ID int, IDValues int)
系統(tǒng)臨時(shí)表:create table ##xx(ID int, IDValues int)

區(qū)別:
用戶(hù)臨時(shí)表只對(duì)創(chuàng)建這個(gè)表的用戶(hù)的Session可見(jiàn),對(duì)其他進(jìn)程是不可見(jiàn)的.
當(dāng)創(chuàng)建它的進(jìn)程消失時(shí)這個(gè)臨時(shí)表就自動(dòng)刪除.

全局臨時(shí)表對(duì)整個(gè)SQL Server實(shí)例都可見(jiàn),但是所有訪問(wèn)它的Session都消失的時(shí)候,它也自動(dòng)刪除.

6.sqlserver2000是一種大型數(shù)據(jù)庫(kù)，他的存儲(chǔ)容量只受存儲(chǔ)介質(zhì)的限制，請(qǐng)問(wèn)它是通過(guò)什么方式實(shí)現(xiàn)這種無(wú)限容量機(jī)制的。
------------------------------------------
它的所有數(shù)據(jù)都存儲(chǔ)在數(shù)據(jù)文件中(*.dbf),所以只要文件夠大,SQL Server的存儲(chǔ)容量是可以擴(kuò)大的.

SQL Server 2000 數(shù)據(jù)庫(kù)有三種類(lèi)型的文件：

主要數(shù)據(jù)文件
主要數(shù)據(jù)文件是數(shù)據(jù)庫(kù)的起點(diǎn)，指向數(shù)據(jù)庫(kù)中文件的其它部分。每個(gè)數(shù)據(jù)庫(kù)都有一個(gè)主要數(shù)據(jù)文件。主要數(shù)據(jù)文件的推薦文件擴(kuò)展名是 .mdf。

次要數(shù)據(jù)文件
次要數(shù)據(jù)文件包含除主要數(shù)據(jù)文件外的所有數(shù)據(jù)文件。有些數(shù)據(jù)庫(kù)可能沒(méi)有次要數(shù)據(jù)文件，而有些數(shù)據(jù)庫(kù)則有多個(gè)次要數(shù)據(jù)文件。次要數(shù)據(jù)文件的推薦文件擴(kuò)展名是 .ndf。

日志文件
日志文件包含恢復(fù)數(shù)據(jù)庫(kù)所需的所有日志信息。每個(gè)數(shù)據(jù)庫(kù)必須至少有一個(gè)日志文件，但可以不止一個(gè)。日志文件的推薦文件擴(kuò)展名是 .ldf。

7.請(qǐng)用一個(gè)sql語(yǔ)句得出結(jié)果
從table1,table2中取出如table3所列格式數(shù)據(jù)，注意提供的數(shù)據(jù)及結(jié)果不準(zhǔn)確，只是作為一個(gè)格式向大家請(qǐng)教。
如使用存儲(chǔ)過(guò)程也可以。

8.華為一道面試題
一個(gè)表中的Id有多個(gè)記錄，把所有這個(gè)id的記錄查出來(lái)，并顯示共有多少條記錄數(shù)。
------------------------------------------
select id, Count（*) from tb group by id having count(*)>1

AOP對(duì)我來(lái)說(shuō)到現(xiàn)在還沒(méi)真正的理解，昨天晚上又把《Spring開(kāi)發(fā) 手冊(cè)》和《精通Spring》的AOP部分看了哈可是還是云里霧里的，要是叫我說(shuō)出AOP的思想我肯定打哽心里是明白會(huì)用，可就是說(shuō)不上來(lái)（丟人了....).。
我現(xiàn)在就把我所能說(shuō)的都說(shuō)出來(lái)啊，說(shuō)的不對(duì)大家別罵我，要是能對(duì)AOP有很好理解的麻煩給我留個(gè)言，給小弟帶來(lái)點(diǎn)感悟。。。先謝謝啦。
我認(rèn)為AOP的實(shí)現(xiàn)其實(shí)就是靠的就是代理Bean（PoxyFactoryBean）和攔截器(Interceptor)來(lái)實(shí)現(xiàn)的。
AOP中有幾個(gè)關(guān)鍵字Aspect,advice,pointCut,target,......
Aspect 就是將你想往目標(biāo)對(duì)象中插入的東西（如事務(wù)，日志），將這些日志，事務(wù)封裝成一個(gè)類(lèi)也就成了Aspect了。
advice 是可是說(shuō)是Aspect中的一個(gè)方法吧。
pointCut 是目標(biāo)對(duì)象中的一個(gè)方法，也就是你想在目標(biāo)對(duì)像的哪個(gè)位置織入你 的Advice。
target 就是你的目標(biāo)對(duì)象啦

Spring AOP

IOC 個(gè)人理解
從字面意思來(lái)說(shuō)是控制反轉(zhuǎn)，利用依賴(lài)注入模式將原來(lái)組件依賴(lài)于對(duì)象的關(guān)系，改變成組件依賴(lài)于抽象接口，將應(yīng)用程序依賴(lài)于容器變成容器管理應(yīng)用程序。為了調(diào)用IOC容器，組件必須利用BeanFactory或ApplicationContext，利用他們可以管理容器中的Bean實(shí)例的生命周期，用getBean(String ...)方法得到Bean實(shí)例，ApplicationContext在BeanFactory的基礎(chǔ)之上實(shí)現(xiàn)了擴(kuò)展增加了資源取得，消息解析，事件處理等功能，使得Spring的IOC容器來(lái)協(xié)調(diào)各組件間相互的依賴(lài)關(guān)系。
