使用ODBC连接达梦DM8数据库

使用 Wyn 进行报表和 BI 设计时，原始数据往往来源于多种数据源，本文介绍 Wyn 连接达梦 DM8 数据库的详细教程。

重点：利用 ODBC 驱动连接达梦 DM8 数据库。

操作介绍

1. 准备好数据库环境，并打开 ODBC 数据源管理器。

在 Windows 控制面板中，单击管理工具，选择 ODBC 数据源(32位)或(64位)，双击打开。

2. 添加新 DSN 并选择正确的驱动程序。

在系统DSN标签下点击添加，找到DM8 ODBC DRIVER。如果本机上已经正常的安装过达梦数据库，并且在安装的时候选择了安装驱动相关组件，则这里可以直接找到对应的DLL。

3. 设置数据源名称并配置对应的连接参数。

配置好 IP 地址，端口号，用户名密码后，可以点击测试连接，测试成功，点击确定，则该数据源配置成功。

填写 ODBC 连接字符串，并进行测试连接，测试通过即可使用该数据源。

连接字符串：Dsn=DM8;description=达梦数据库;server=localhost;uid=SYSDBA;tcp_port=5236;language=CHINESE

与 Windows 的 ODBC 数据源管理器中配置的一致。
