最近有一个需求，是从数据库中取数据，同步到系统的Currency上。

我在使用Enterprise jar 时候总是提示Invalid—Type的错误，各种看大神的文章发现，针对这个问题，我们要采用Partner jar，如果这个不知道怎么生成，请参考SOAP手册。

放下代码，大家参考下：以下是最终版本，之前遇到的错误是：

com.sforce.ws.SoapFaultException: A duplicate value was specified for field ‘Id‘ in object ‘DatedConversionRate‘,  duplicate value ‘04wO00000004K7OIAU‘ prior value ‘04wO00000004K7OIAU‘    Debug跟进去发下Id有两个，这个比较奇怪，后来加上一句s.setField("Id", null); 就Ok了
