MS-SQL数据库开拓—精典

1.按姓氏笔画排序:
Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as

2.数据库加密:
select encrypt('原始暗码')
select pwdencrypt('原始暗码')
select pwdcompare('原始暗码','加密后暗码') = 1--沟通；不然不沟通 encrypt('原始暗码')
select pwdencrypt('原始暗码')
select pwdcompare('原始暗码','加密后暗码') = 1--沟通；不然不沟通

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.查察硬盘分区:
EXEC master..xp_fixeddrives

5.较量A,B表是否相称:
if (select checksum_agg(binary_checksum(*)) from A)
    =
   (select checksum_agg(binary_checksum(*)) from B)
print '相称'
else
print '不相称'

6.杀掉全部的变乱探察器历程:
DECLARE hcforeach CURSOR GLOBAL FOR SELECT 'kill '+RTRIM(spid) FROM master.dbo.sysprocesses
WHERE program_name IN('SQL profiler',N'SQL 变乱探查器')
EXEC sp_msforeach_worker '?'

7.记录搜刮:
开头到N笔记录
Select Top N * From 表
-------------------------------
N到M笔记录(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到末了记录
Select Top N * From 表 Order by ID Desc

8.怎样修改数据库的名称:
sp_renamedb 'old_name', 'new_name' 

9：获取当前数据库中的全部用户表
select Name from sysobjects where xtype='u' and status>=0

10：获取某一个表的全部字段
select name from syscolumns where id=object_id('表名')

11：查察与某一个表相干的视图、存储进程、函数
select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'

12：查察当前数据库中全部存储进程
select name as 存储进程名称 from sysobjects where xtype='P'

13：查询用户建设的全部数据库
select * from master..sysdatabases D where sid not in(select sid from master..syslogins where name='sa')
可能
select dbid, name AS DB_NAME from master..sysdatabases where sid <> 0x01

14：查询某一个表的字段和数据范例
select column_name,data_type from information_schema.columns
where table_name = '表名'
