打开CMD令命
执行:sqlcmd/?
这是sqlcmd令命的一些助帮息信
通过下面可以道知怎么连据数库了
执行:sqlcmd -S 服务器地址 -d 据数库称名 -U 用户码密 -P 码密
以下是操纵据数库的一下令命
0. 创立据数库 CREATE DATABASE DB001 1. 创立用户 CREATE LOGIN USER1 WITH PASSWORD = 'USER_PW'; 2. 修改据数的有所者 USE DB001 exec sp_changedbowner 'USER1' GO 3. 设置READ_COMMITTED_SNAPSHOT ALTER DATABASE [DB001] SET READ_COMMITTED_SNAPSHOT ON GO 4.修改字符集 ALTER DATABASE DB001 COLLATE SQL_Latin1_General_CP437_CS_AS GO 5. 获得有所据数库名: Select Name FROM Master..SysDatabases 6 . 获得有所表名: select name from sysobjects where type='U' XType='U':示表有所用户表; XType='S':示表有所系统表; 7. 获得有所字段名: Select Name from SysColumns Where id=Object_Id('TableName') 8. 看查与某一个表相干的视图、存储过程、数函 select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%TableName%' 9. 查询某一个表的字段和据数类型 select column_name,data_type from information_schema.columns where table_name = N'TableName' 10. 获得据数库文件径路 select ltrim(rtrim(filename)) from dbname ..sysfiles where charindex('MDF',filename)>0 or select ltrim(rtrim(filename)) from dbname ..sysfiles where charindex('LDF',filename)>0

文章结束给大家分享下程序员的一些笑话语录:
3G普不普及现在已经不是看终端了,而是看应用,有好的,便宜实用的应用,花1000多买个能用的智能手机应该不是什么难事。反过来说,你200元拿一个智能手机,没有好的应用,看个电影要几十元,也是没人用3G。
