MongoDump query with BinData

c#, mongodb, mongodb-.net-driver

Solution

This needs a lot of escaping, unfortunately. Also, you'll have to use the `$binary` representation instead, e.g.

mongodump --host localhost --db test --collection bd --query 
"{\"_id\" : { \"$binary\" : \"ryBRQ+Px0kGRsZofJhHgqg==\", \"$type\" : \"03\" } }"

Note that `$type` must be a hex string, not a number.

In linux, you'll also have to escape the `$` to `\$`.

Problem

The Mongodump documentation specifies you can dump using a specific query i.e. ``` mongodump --host localhost --db mydb --collection testCollection --query "{SomeKey: 'some value'}" ``` I'm storing _ids fields as BinData, is it possible to query on this? I've tried ``` mongodump --host localhost --db mydb --collection testCollection --query "{_id: 'BinData(3,ryBRQ+Px0kGRsZofJhHgqg==)'}" ``` With no luck.
