MS-SQL數(shù)據(jù)庫開發(fā)常用代碼

這些都是平時手機的一些MSSQL數(shù)據(jù)庫開發(fā)的小代碼，大家有心的可以記一下。
    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)庫的名稱:
    sp_renamedb 'old_name', 'new_name'
    9：獲取當前數(shù)據(jù)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(guān)的視圖、存儲過程、函數(shù)
    select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'
    12：查看當前數(shù)據(jù)庫中所有存儲過程
    select name as 存儲過程名稱 from sysobjects where xtype='P'
    13：查詢用戶創(chuàng)建的所有數(shù)據(jù)庫
    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].[標題]:
    Select * From TableName Order By CustomerName
    [n].[標題]:
    Select * From TableName Order By CustomerName
