第二步：把Driver放在一个目录下（我放在D:\R\JDBC）

第三步：为R安装RJDBC package    install.packages("RJDBC")

安装成功后，可以键入如下代码进行连接Teradata：

<span class="GJWPQFQDB4 ace_keyword" style="word-wrap: break-word; color: blue;">
<span class="GJWPQFQDN4 ace_keyword" style="word-wrap: break-word; white-space: pre;">> </span>jdbc.conn<-dbConnect(jdbc.drv, "jdbc:teradata://tdp.vip.XXX.com", "userID", "passWD") #打开数据库连接</span>

<span style="color:#0000ff;">
</span>

<span style="color:#0000ff;">#此处注意 </span><span style="color: blue; font-size: 10pt; line-height: 1.2;">userID、</span><span style="color: blue; font-size: 10pt; line-height: 1.2;">passWD填写的是自己的数据库用户名和密码；jdbc:teradata://数据库的ip地址/TMODE=,CHARSET=,CLIENT_CHARSET=,LOB_SUPPORT=,DATABASE=（以及其他的相关设置）</span>

<span style="color: blue; font-size: 10pt; line-height: 1.2;">
</span>

<span style="color: blue; font-size: 10pt; line-height: 1.2;">（1）查询当前的系统时间、用户以及会话</span>

<span class="GJWPQFQDB4 ace_keyword" style="word-wrap: break-word; color: blue;"><br style="word-wrap: break-word;" /></span>

<span class="GJWPQFQDB4 ace_keyword" style="word-wrap: break-word; color: blue;">dbGetQuery(jdbc.conn, "select current_date, user, session")</span>

<span class="GJWPQFQDB4 ace_keyword" style="word-wrap: break-word; color: blue;">
</span>

输出结果的数据类型为data.frame
