1.按姓氏筆劃排序:Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as 2.資料庫加密:select encrypt('原始密碼')select pwdencrypt('原始密碼')select pwdcompare('原始密碼','加密後密碼') = 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','加密後密碼') = 1--相同；否則不相同3.取回表中欄位: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.查看硬碟分區:EXEC master..xp_fixeddrives5.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 '?'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到結尾記錄Select Top N * From 表 Order by ID Desc8.如何修改資料庫的名稱:sp_renamedb 'old_name', 'new_name' 9：獲取當前資料庫中的所有用戶表select Name from sysobjects where xtype='u' and status>=010：獲取某一個表的所有欄位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select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'12：查看當前資料庫中所有存儲過程select name as 存儲過程名稱 from sysobjects where xtype='P'13：查詢用戶創建的所有資料庫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 ＜> 0x0114：查詢某一個表的欄位和資料類型select column_name,data_type from information_schema.columnswhere table_name = '表名' [n].[標題]:Select * From TableName Order By CustomerName [n].[標題]:Select * From TableName Order By CustomerName
