连接局域网中的数据库
需要知道数据库主机的IP地址,数据库端口号,服务名称,数据库账户及密码才可以连版接。
1、首先在权本地oracle的安装目录下找到找到tnsnames.ora文件。一般路径为:~oracleproct10.2.0db_1 etworkADMIN
4、用正确的账户名及密码登录,就可以连接成功。
㈡ 怎样连接局域网中的mysql数据库
1首先要确保内网应用正常。
2明确内网mysql数据库访问地址,并确保mysql数据库服务正常。如本地mysql数据库访问地址是localhost:3306。
3然后使用自己的帐号登录nat123。然后选择主面板/端口映射列表/添加映射。
4设置映射信息。选择全端口映射类型。填写内网mysql数据库服务器IP地址,和外网访问的域名。可以使用自己的域名,也可以使用免费二级域名。将鼠标放在输入框有向导提示。
5访问者打开mysql全端口映射后的域名和访问端口。如在添加访问地址时,同时勾选允许局域网访问,则在访问者局域网内都可以访问。
6查看访问者状态。鼠标放在访问者图标上,提示当前状态信息。
7在使用访问者本机,可以进行访问mysql数据库。访问地址是本地访问者打开的域名端口
㈢ 怎么用excel和access实现局域网数据库
您好,方法有很多的
例如
局域网中有Sharepoint服务端,可以直接通过Excel访问服务端上的数据库,
如下图,但Sharepoint似乎并不是非常普及,所以还提供了其他方法
注意:
1.此方法的缺点在于仅限单向连接,即Excel端发生更改,Access端可同步接收Excel的数据变动,但在Access端无法对数据进行操作
2.务必常常对Access进行存档,否则Excel端关闭后Access端可能发生数据丢失
拓展:
另外还可以通过VB创建控件的方法,在IE中进行数据的浏览与更改,此方法将同时同步Excel与Access中的数据,但需要一定的VB编程基础,这里提供源码,有兴趣可以研究研究,并不是很难

㈣ 如何连接并使用局域网内另一台电脑的sql数据库。
工具/材料:Management Studio。
1、首先在桌面上,点击“Management Studio”图标。
㈤ 局域网内怎么连接到另外一台电脑的数据库
前提是都有数据库管理系统,其中一个作为客户端,另一个为服务器,服务器上要为这个客户端授权一个帐号,比如mysql在命令行下:
mysql -h 192.168.0.9 -u myaccount -p
回车以后提示输入密码,输入正确就会连接上了,出现:
mysql>
