1.按姓氏筆畫排序:
Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as
2.數據庫加密:
select encrypt(@#原始密碼@#)
select pwdencrypt(@#原始密碼@#)
select pwdcompare(@#原始密碼@#,@#加密後密碼@#) = 1--相同；否則不相同 encrypt(@#原始密碼@#)
select pwdencrypt(@#原始密碼@#)
select pwdcompare(@#原始密碼@#,@#加密後密碼@#) = 1--相同；否則不相同
3.取回表中字段:
declare @list varchar(1000),@sql nvarchar(1000)
select @list=@list+@#,@#+b.name from sysobjects a,syscolumns b where a.id=b.id and a.name=@#表A@#
set @sql=@#select @#+right(@list,len(@list)-1)+@# from 表A@#
exec (@sql)
4.查看硬盤分區:
EXEC master..xp_fixeddrives
5.比較A,B表是否相等:
if (select checksum_agg(binary_checksum(*)) from A)
=
(select checksum_agg(binary_checksum(*)) from B)
print @#相等@#
else
print @#不相等@#
6.殺掉所有的事件探察器進程:
DECLARE hcforeach CURSOR GLOBAL FOR SELECT @#kill @#+RTRIM(spid) FROM master.dbo.sysprocesses
WHERE program_name IN(@#SQL profiler@#,N@#SQL 事件探查器@#)
EXEC sp_msforeach_worker @#?@#
7.記錄搜索:
開頭到N條記錄
Select Top N * From 表
-------------------------------
N到M條記錄(要有主索引ID)
Select Top M-N * From 表 Where ID in (Select Top M ID From 表) Order by ID Desc
----------------------------------
N到結尾記錄
Select Top N * From 表 Order by ID Desc
8.如何修改數據庫的名稱:
sp_renamedb @#old_name@#, @#new_name@#
9：獲取當前數據庫中的所有用戶表
select Name from sysobjects where xtype=@#u@# and status>=0
10：獲取某一個表的所有字段
select name from syscolumns where id=object_id(@#表名@#)
11：查看與某一個表相關的視圖、存儲過程、函數
select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like @#%表名%@#
12：查看當前數據庫中所有存儲過程
select name as 存儲過程名稱 from sysobjects where xtype=@#P@#
