How to Export Sorted Data Using Mongoexport?

Question

I have a collection in mongo which has name and count fields.

{name:'myName',count:5}

Is it possible to sort data by count and export as json using mongoexport?

Accepted Answer

Starting with MongoDB 2.6, you can pass --sort to mongoexport directly:

mongoexport --db mydatabase -c people --fields name,age --sort "{name: 1, age: 1}"

Accepted Answer

Actually you can, but you have to use special params. Here's a sample (redirecting to file):

$ mongoexport  -q '{ $query: {count: {$gt:0}}, $orderby: {count: -1} }' -d database -c collection > data_dump.json

The $query part is not strictly necessary, but I included it because of this bug on GitHub (fixed now, but only just).

Answer 3

You can't pass in an argument to sort your documents by a specific key when using mongoexport.

The way to do this would be to write your own script.

Hope this helps.
