sql 常用語句積累 (隨時更新)
1.如何刪除表中的重複記錄?(這裡指記錄的每個欄位都要相同)
select distinct * into #temp from tab
delete tab
insert tab select * from #temp
drop table #temp
1.DISTINCT 是 SUM、AVG 和 COUNT 的可選關鍵字。如果使用 DISTINCT,那麼在計算總和、平均值或計數之前,先消除重複的值。
如果使用 DISTINCT 關鍵字,表示式必須只包含列名。而不能包含算術表示式。
以下查詢返回商務書籍的平均價格(不包括重複的值):
USE pubs
SELECT AVG(DISTINCT price)
FROM titles
WHERE type = 'business'
2.DISTINCT 關鍵字可從 SELECT 語句的結果中除去重複的行,distinct 後面的欄位可以是多個或*,是一個那就各軍兵種那個欄位來取不重複的,
如果是多個,那就是篩選所選的字短都相同的記錄.
USE pubs
SELECT DISTINCT au_id--按照一個欄位篩選
FROM titleauthor
USE pubs
SELECT DISTINCT au_id,au_name --按照兩個欄位篩選
FROM titleauthor
2.怎樣返回資料庫中使用者表的表單名
select name from sysobjects where xtype='U'
select name from sysobjects where xtype = 'u' and status >=0

各位大大請幫個忙,
一個表中A欄位是int型的自動編號,B欄位是首先要獲取A欄位已有的自動編號資料再經過加入時間等後生成的資料,表如下
C,D(日期),E為其他資料
列名 A(自動遞加) B(A欄位資料+日期等) C D E
---------------------------------------------------
1 A+D . . .
2 A+D . . .
---- 建立測試環境:
create table table1(a int identity,b varchar(20),c datetime,d datetime,e int)
create proc proc1
@c datetime,
@d datetime,

declare @f int
insert table1 (c,d,e) values(@c,@d,@e)
select @f=@@identity
if @@error=0
begin
update table1 set b=convert(varchar,a)+convert(varchar(12),d,120) where a=@f
end
---執行儲存過程

(3)你說得沒錯 其實你那樣用事務的畫沒什麼作用,每個儲存過程都是一個事務。如果用事務最好有出錯的處理是否回滾之類的東西。但是要考慮好表之間的關聯性,如果都是一些單獨的表,可以分幾個事務處理,如果是父子表還是要放在一個事務裡面。保證其資料的準確
性。
4請給條如何找出重複記錄的SQL語句
表 A ,有2個欄位 Id--Int,Name--Varchar(20)
假設 表 A 裡儲存了30萬記錄,其中有1條記錄的 ID 是重複的,現在我想找出該條記錄ID,SQL語句?
select ID from A group by ID having count(1)>1
有一個觸發器,觸發該觸發器的方法有insert,update,delete
但是,我如何可以判斷我到底是用哪種方法觸發該觸發器
http://community.csdn.net/Expert/topic/4234/4234894.xml?temp=.3572657
create trigger 觸發名 on 表名
instead of insert,update,delete
as
--insert插入
if not exists(select 1 from deleted)
begin
列印插入
end
--update更新
if exists(select 1 from inserted) and exists(select 1 from deleted)
begin
列印修改
end
--delete刪除
if not exists(select 1 from inserted)
begin
列印刪除
end
