Unwind document

[Jackson]

Hello all!!!

How can I create project for one document:

{

_id:1,

field1: 5,

field2: 10,

field3: 25

}

to have several documents:

{

_id:2,

field1: 5

},

{

_id:3,

field2: 10

},

{

_id:4,

field3: 25

}

or to have one document with array:

{

_id:1,

fields: [{name:"field1", count:5},{ name:"field2", count:10 },{ name:"field3", count:25 }]

}

?

PS: Using Aggregation Framework

This is not possible with the aggregation framework. You can only
unwind arrays, and creating arrays with the aggregation framework is
not currently supported.

It's too bad... Are there any plans to implement such functionality in future?

[Jason Rassi]

I don't believe so.

Ok, thank you

You can file a SERVER feature request at jira.mongodb.org.  This feature would be similiar to PIVOT in Sql Server I think.
