1.按姓氏筆畫排序:
Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as
2.資料庫加密:
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.取回表中欄位:
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.查看硬碟分區:
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 '?'
'www.knowsky.com
7.記錄搜尋:
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.如何修改資料庫的名稱:
sp_renamedb 'old_name', 'new_name'
9：擷取當前資料庫中的所有使用者表
select Name from sysobjects where xtype='u' and status>=0
10：擷取某一個表的所有欄位
select name from syscolumns where id=object_id('表名')
11：查看與某一個表相關的視圖、預存程序、函數
select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'
12：查看當前資料庫中所有預存程序
select name as 預存程序名稱 from sysobjects where xtype='P'
13：查詢使用者建立的所有資料庫
