fetchPlan returning extra properties

I’m using OrientDB v.2.1.1 with useLightweightEdges property set to true. Using fetchPlan queries often return extra properties non included in the query or even some of properties excluded in more ways.

Here is an example:

Given this simple structure

User    V     #13
Event   V     #14
Org     V     #15
Media   V     #16

admin   E     User  --> Org
follow  E     User  --> Org
author  E     Event --> Org
avatar  E     Org   --> Media
thumb   E     Event --> Media

I need to write a query that fetches a specific Event, its relative thumb, author and the author’s avatar. Nothing else.

1st query:

SELECT @this.toJSON('rid,class,fetchPlan:[*]in_*:-2 [*]out_*:-2 out_thumb:0 out_author:0 out_author.out_avatar:0') FROM Event WHERE @rid = #14:8

Returns:

{
    "@rid": "#14:8",
    "@class": "Event",
    "name": "EVENT_TEST",
    "out_author": [
        {
            "@rid": "#15:0",
            "@class": "Org",
            "name": "ORG_TEST",
            ! "in_admin": [ "#13:0", "#13:5", "#13:6", "#13:9", "#13:10", "#13:13" ],
            ! "in_follow": [ "#13:0", "#13:4", "#13:5", "#13:6", "#13:14", "#13:15" ],
            ! "in_author": [ "#14:6", "#14:7", "#14:8", "#14:9", "#14:10", "#14:11" ],
            "out_avatar": [
                {
                    "@rid": "#16:2",
                    "@class": "Media",
                    "url": "www.image.com",
                    ! "in_thumb": [ "#14:4", "#14:6", "#14:7", "#14:12", "#14:14", "#14:15" ],
                    ! "in_avatar": [ "#15:0" ]
                }
            ]
        }
    ],
    "out_thumb": [
        {
            "@rid": "#16:1",
            "@class": "Media",
            "url": "www.image.com",
            ! "in_thumb": [ "#14:2", "#14:5", "#14:8", "#14:9", "#14:10", "#14:13" ],
            ! "in_avatar": [ "#15:2" ]
        }
    ]
}

Where these properties should have been excluded: out_author.in_admin out_author.in_follow out_author.in_author out_author.out_avatar.in_thumb out_author.out_avatar.in_avatar out_thumb.in_thumb out_thumb.in_avatar

2nd query:

made by adding some parameters to the 1st query to explicitly exclude the extra properties

SELECT @this.toJSON('rid,class,fetchPlan:[*]in_*:-2 [*]out_*:-2 out_thumb:0 out_author:0 out_author.out_avatar:0 [*]in_avatar:-2 [*]in_thumb:-2 [*]in_author:-2 [*]in_admin:-2 [*]in_follow:-2') FROM Event WHERE @rid = #14:8

Returns

{
    "@rid": "#14:8",
    "@class": "Event",
    "name": "EVENT_TEST",
    "out_author": [
        {
            "@rid": "#15:0",
            "@class": "Org",
            "name": "ORG_TEST",
            ! "in_admin": [ "#13:0", "#13:5", "#13:6", "#13:9", "#13:10", "#13:13" ],
            ! "in_follow": [ "#13:0", "#13:4", "#13:5", "#13:6", "#13:14", "#13:15" ],
            "out_avatar": [
                {
                    "@rid": "#16:2",
                    "@class": "Media",
                    "url": "www.image.com"
                }
            ]
        }
    ],
    "out_thumb": [
        {
            "@rid": "#16:1",
            "@class": "Media",
            "url": "www.image.com"
        }
    ]
}

Partially works since removes out_author.in_author out_author.out_avatar.in_thumb out_author.out_avatar.in_avatar out_thumb.in_thumb out_thumb.in_avatar

But it doesn’t remove out_author.in_admin out_author.in_follow

3nd query:

made by adding some parameters to the 2st query to even more explicitly exclude the extra properties remained

SELECT @this.toJSON('rid,class,fetchPlan:[*]in_*:-2 [*]out_*:-2 out_thumb:0 out_author:0 out_author.out_avatar:0 [*]in_avatar:-2 [*]in_thumb:-2 [*]in_author:-2 [*]in_admin:-2 [*]in_follow:-2 out_author.in_admin:-2 out_author.in_follow:-2') FROM Event WHERE @rid = #14:8

Returns:

// The same as for 2nd query

…even nicer: use “as” to rename the edges:

select
  outE("thumb").include("url","type","size") as thumb,
  outE("author").include("name") as author,
  outE("author").outE("avatar").include("url") as avatar
from #13:0

I don’t understand why you are using the toJSON-function, this looks so complicated… why not use the outE()-function with include()?

select outE("thumb").include("url","type","size"), outE("author").include("name"), outE("author").outE("avatar").include("url") from #14:8

Btw if you replace the ... from Event where @rid with select ... from #14:8 your query is faster.
