Question

我一直在尝试使用所有字段从http://www.transtats.bts.gov/DL_SelectFields.asp?Table_ID=293&DB_Short_Name=Air%20Carriers导入文件。

为此我从终端做了以下命令：

mongoimport -d local -c flightdata --type csv --file 1073242969_T_T100_SEGMENT_ALL_CARRIER_modified.csv --headerline

问题是当我运行命令时，我得到以下输出：

但是当我去检查数据库时：

>use local
>db.flightdata.count()
1

所以这意味着只加载了第一条记录。还尝试使用未加引号的字段并引用。

关于我做错了什么想法？

无法单独找到ID字段

Answer 1

看起来你的所有记录都有_id字段，该字段应该是唯一的 - 但它们都具有相同的值，＆＃39; null＆＃39;。＆＃39; mongoimport＆＃39;有一个不幸的属性，只检查前十个和最后一个文件的成功插入。因此，这11项检查会得到10个错误。

EDIT 证明您正在尝试将其导入＆＃34; local＆＃34;存在供系统使用（复制）的数据库，你不应该把自己的集合放在那里。

如果您选择将数据库命名为＆＃34; local＆＃34;你的导入将会成功。
