unix下oracle错误有一个很好的查询方式:

输入oerr ora 错误号

>$oerr ora 00001
00001, 00000, "unique constraint (%s.%s) violated"
// *Cause: An UPDATE or INSERT statement attempted to insert a duplicate key.
//         For Trusted Oracle configured in DBMS MAC mode, you may see
//         this message if a duplicate entry exists at a different level.
// *Action: Either remove the unique restriction or do not insert the key.
>$

比较详细的说明了,虽然我英文不好,看起来费力.
