Load into lêer
> Db.load ("file_name.json")
Verfris huidige gelaai into lêer
> Db.refresh ()
Stoor stroom in-geheue db in huidige gelaai into lêer
> Db.save ()
Stoor navraag resultate as into lêer
> Db.capture ("save_to_file_name.json")
Ekstra: voer na enige db.find () / db.group () / db.count () bevel
Voeg nuwe rekord
> Db.insert (json_item)
Verwyder rekord
> Db.remove (navraag)
Vind 'n ry
> Db.find (navraag)
Ekstra: voeg "$ return": [veld1, veld2] in navraag sal veld1 en veld2 net terug
Tel 'n ry dat pasmaat navraag
> Db.count (navraag)
Groep 'n ry met 'n sleutel:
> Db.group (navraag)
voeg "$ sleutel": "titel" in navraag sal met behulp van die veld titel as jou groepering sleutel
Query
Into struktuur voorbeelde:
[{"Id": 1, "naam": "Een", "titel": "Mnr", "e-pos": "one@mailinator.com", "telling": {"wiskunde": 80, "wetenskap" : 80}}, {"id": 2, "naam": "Twee", "titel": "Mev", "e-pos": "two@mailinator.com", "score": {"wiskunde": 60 "wetenskap": 70}}, {"id": 3, "naam": "Drie", "titel": "Me", "e-pos": "three@mailinator.com", "score": {" wiskunde ": 75," wetenskap ": 90}}, {" id ": 4," naam ":" Vier "," titel ":" Mev "," e-pos ":" five@mailinator.com "," score ": {" wiskunde ": 60," wetenskap ": 30}}, {" id ": 5," naam ":" Vyf "," titel ":" Mev "," e-pos ":" fivefour@mailinator.com "," telling ": {" wiskunde ": 70," wetenskap ": 60}}]
Pas Presiese, Behalwe, wil en LikeAnd
Filter al item met mev titel: navraag = {"$ titel": "Mev"}
Filter al item met die titel, behalwe Me: navraag = {"$ titel": {"$ ne": "Me"}}
Filter al item soos 'vyf' in e-pos: navraag = {"e-pos": {"$ soos": "vyf"}}
Filter al item soos 'vyf' of 'vier' in e-pos: navraag = {"e-pos": {"$ hou": ["vyf", "vier]}}

Greater en laer as
Filter al wiskunde telling groter as 60: navraag = {"score.math": {"$ gt": 60}}
Filter al wiskunde telling laer as 60: navraag = {"score.math": {"$ lt": 60}}
Filter al wiskunde telling groter as gelyke 60: navraag = {"score.math": {"$ GTE": 60}}
Filter al wiskunde telling laer as gelyke 60: navraag = {"score.math": {"$ LTE": 60}}
