Gruppi funzioni↵
Nell'Interfaccia del Field Calc (e nel costruttore di espressione) è presente, nella parte centrale, una sezione che raccoglie i Gruppi delle Funzioni elencate sotto:
| Gruppo funzioni | nro funzioni* | Descrizione | info |
|---|---|---|---|
| Aggrega | (23/23) | Contiene funzioni che aggregano valori nei livelli e campi. | aggiornate a QGIS 3.36 |
| Array | (36/36) | Questo gruppo contiene funzioni espressione per la creazione e la manipolazione di array (noti anche come strutture dati ad elenco). L'ordine dei valori all'interno dell'array è importante, al contrario della struttura dati 'a mappa', in cui l'ordine delle coppie chiave-valore è irrilevante e i valori vengono identificati dalle loro chiavi. | aggiornate a QGIS 3.28 |
| Campi e valori | (1/1) | Contiene un elenco di campi del layer. Si possono ottenere valori campione con il click del tasto destro del mouse. Seleziona il nome del campo dall'elenco e fai click con il tasto destro per aprire il menù con le opzioni per caricare un campione di valori dal campo selezionato. | Elenco dei campi del layer selezionato QGIS 3.28 |
| Colore | (17/17) | Questo gruppo contiene funzioni per manipolare i colori | Per manipolare i colori |

| Record e attributi | (17/17) | Questo gruppo contiene funzioni che operano sugli identificativi dei record. | aggiornate a QGIS 3.30 |
| Sensors | Questo gruppo contiene le funzioni per interagire con i sensori | a QGIS 3.30 |
|
| Relazioni | (?) | Visibile solo se ci sono relazioni di progetto | |
