数据库中的主键在填报中不需要该字段，并且该主键字段在数据库中是自增字段，这是什么原因呢。。。请各位帮小弟看一下。。谢谢

你是不是没设置报表主键？没有设置报表主键的话就是进行insert操作，这个时候数据库主键字段又没用到，导致那个字段插入的是null，而数据库主键是不允许为空的，就出错了
数据库主键和报表主键作用不同
数据库主键是确保数据唯一性
报表主键主要是用来判断，编辑的记录数据库中有没有，有的话就做update,没有的话就是insert

那就是插入数据的时候数据库主键为null
oracle自增长你是用序列和触发器做的么？我记得好像对于这样的数据库主键字段，在FR的报表填报属性中随便填入一个值，让他不为空，来避免null的情况，可以试试
