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('原始密码')
    select pwdencrypt('原始密码')
    select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同 encrypt('原始密码')
    select pwdencrypt('原始密码')
    select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同
    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.查看硬盘分区:
    EXEC master..xp_fixeddrives
    5.比较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.杀掉所有的事件探察器进程:
    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.记录搜索:
    开头到N条记录
    Select Top N * From 表
    -------------------------------
    N到M条记录(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到结尾记录
    Select Top N * From 表 Order by ID Desc
    8.如何修改数据库的名称:
    sp_renamedb 'old_name', 'new_name'
    9：获取当前数据库中的所有用户表
    select Name from sysobjects where xtype='u' and status>=0
    10：获取某一个表的所有字段
    select name from syscolumns where id=object_id('表名')
    11：查看与某一个表相关的视图、存储过程、函数
    select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'
    12：查看当前数据库中所有存储过程
    select name as 存储过程名称 from sysobjects where xtype='P'
    13：查询用户创建的所有数据库
    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：查询某一个表的字段和数据类型
    select column_name,data_type from information_schema.columns
    where table_name = '表名'
    [n].[标题]:
    Select * From TableName Order By CustomerName
    [n].[标题]:
    Select * From TableName Order By CustomerName
