嗨，大家好，我是pentaho新手，使用pentaho kettle version 7.1和mysql jdbc driver版本是5.1.43。我在不同的数据库中有两个相同的表。我们叫db1是第一个在生产中托管的数据库，而db2是另一个在开发中托管的数据库。 db1和db2都有相同的表，称为dashboard_user。表dashboard_user有主键id这是autoincrement。但问题是，当我试图从生产，而不删除现有的数据在发展中复制值来发展它返回象下面这样：Pentaho错误：非主键重复条目

它说：
Error inserting/updating row 2017/08/16 15:13:02 - Table output.0 - Duplicate entry 'sonar.id' for key 'index_dashboard_domains_on_domain' 2017/08/16 15:13:02 - Table output.0 - 2017/08/16 15:13:02 - Table output.0 - 2017/08/16 15:13:02 - Table output.0 - at org.pentaho.di.trans.steps.tableoutput.TableOutput.writeToTable(TableOutput.java:385)
sonar.id是用户名，而不是主键，我想知道为什么我无法传输数据？但返回错误，说重复的键？
