Description
It would help if we can add an example on how to export sub documents in an array.
For example, if we have a document like this:
{
|
"_id" : ObjectId("527b09b18c6f25a12b5aadb6"),
|
"a" : {
|
"b" : [
|
{
|
"c" : 2
|
},
|
{
|
"c" : 3
|
}
|
]
|
}
|
}
|
To export the first element of array b, use “a.b.0” as the field name:
mongoexport -d <database> -c <collection> -f "a.b.0"
|
To export the value of c in the first element of array b, use “a.b.0.c” as the field name:
mongoexport -d <database> -c <collection> -f "a.b.0.c"
