ORA-00001: 违反唯一约束条件

 首先排除一下,要插入的数据(主键)是否和要插入的表里有重复数据,如果有先过滤一下

delete from 数据源表 where 主键字段 in (select 主键字段 from 要插入的表)

 

然后看下要插入的新数据(主键)本身是否有重复数据,如果有需要去重

 DELETE from 需要去重表 WHERE (主键) IN (SELECT 主键 FROM 表 GROUP BY 主键 HAVING COUNT(主键) > 1) AND ROWID NOT IN (SELECT MIN(ROWID) FROM 表 GROUP BY 主键 HAVING COUNT(*) > 1);
