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'elseprint '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.sysprocessesWHERE program_name IN('SQL profiler',N'SQL 事件探查器')EXEC sp_msforeach_worker '?''www.mypchelp.cn7.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.columnswhere table_name = '表名'
