即使存在主键和唯一索引，Oracle也允许重复记录

我正在使用OracleBulkCopy将批次中的记录插入Oracle数据库3.在我的表中，为第一批插入了重复的记录，但未能为下一个记录。第一批也应该失败，因为它不应该允许重复的条目！下面你可能会发现我的表'创建脚本'（我已经删除了一些字段）。即使存在主键和唯一索引，Oracle也允许重复记录

任何想法？

没有必要在稍后添加主键约束的列上放置任何索引 - 主键约束将自动添加唯一索引。 – 2014-11-08 11:59:05

我怀疑躺在事实，你cheques_pk指数为unusable状态的麻烦。

它在OracleBulkCopy的第一批instert后变得不可用。 OracleBulkCopy禁用索引并使其不可用，然后在第二批中索引已经不可用，则会引发错误。我想要实现的是禁用第一次插入，以便索引不会变得不可用。 – alwaysVBNET 2014-11-08 14:57:04

即使存在主键和唯一索引，Oracle也允许重复记录
