1.按姓氏筆畫排序:

Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as

2.數(shù)據(jù)庫(kù)加密:

select encrypt('原始密碼')

select pwdencrypt('原始密碼')

select pwdcompare('原始密碼','加密后密碼') = 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','加密后密碼') = 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(qū):

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(jìn)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(jié)尾記錄

Select Top N * From 表 Order by ID Desc

8.如何修改數(shù)據(jù)庫(kù)的名稱:

sp_renamedb 'old_name', 'new_name'

9：獲取當(dāng)前數(shù)據(jù)庫(kù)中的所有用戶表

select Name from sysobjects where xtype='u' and status>=0

10：獲取某一個(gè)表的所有字段

select name from syscolumns where id=object_id('表名')

11：查看與某一個(gè)表相關(guān)的視圖、存儲(chǔ)過(guò)程、函數(shù)

select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'

12：查看當(dāng)前數(shù)據(jù)庫(kù)中所有存儲(chǔ)過(guò)程

select name as 存儲(chǔ)過(guò)程名稱 from sysobjects where xtype='P'

13：查詢用戶創(chuàng)建的所有數(shù)據(jù)庫(kù)

select * from master..sysdatabases D where sid not in(select sid from master..syslogins where name='sa')

或者

select dbid, name AS DB_NAME from master..sysdatabases where sid <> 0x01

14：查詢某一個(gè)表的字段和數(shù)據(jù)類型

select column_name,data_type from information_schema.columns

where table_name = '表名'

[n].[標(biāo)題]:

Select * From TableName Order By CustomerName
