Table.Sort

Sintassi

Table.Sort(table as table, comparisonCriteria as any) as table

Informazioni su

Ordina table mediante l'elenco di uno o più nomi di colonna e facoltativamente comparisonCriteria nel formato { { col1, comparisonCriteria }, {col2} }.

Poiché Power Query talvolta esegue l'offload di determinate operazioni nelle origini dati back-end (note come "riduzione") e talvolta ottimizza le query ignorando le operazioni che non sono strettamente necessarie, in generale non esiste alcuna garanzia sul modo in cui le righe con colonne di ordinamento identiche verranno ordinate. Ad esempio, non è possibile presupporre che la prima riga con un set univoco di valori di colonna venga ordinata per prima. Se si desidera che l'ordinamento si comporti in modo prevedibile, memorizzare prima nel buffer la tabella usando Table.Buffer.

Esempio 1

Ordinare la tabella in base alla colonna "OrderID".

Utilizzo

Table.Sort(
    Table.FromRecords({
        [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100.0],
        [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5.0],
        [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25.0],
        [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200.0],
        [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2.0],
        [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20.0],
        [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
        [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100.0],
        [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
    }),
    {"OrderID"}
)

Output

Table.FromRecords({
    [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100],
    [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5],
    [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25],
    [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200],
    [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2],
    [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20],
    [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
    [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100],
    [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
})

Esempio 2

Ordinare la tabella in base alla colonna "OrderID" in ordine decrescente.

Utilizzo

Table.Sort(
    Table.FromRecords({
        [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100.0],
        [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5.0],
        [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25.0],
        [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200.0],
        [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2.0],
        [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20.0],
        [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
        [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100.0],
        [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
    }),
    {"OrderID", Order.Descending}
)

Output

Table.FromRecords({
    [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25],
    [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100],
    [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
    [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20],
    [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2],
    [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200],
    [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25],
    [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5],
    [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100]
})

Esempio 3

Ordinare la tabella in base alla colonna "CustomerID" quindi "OrderID", con "CustomerID" in ordine decrescente.

Utilizzo

Table.Sort(
    Table.FromRecords({
        [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100.0],
        [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5.0],
        [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25.0],
        [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200.0],
        [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2.0],
        [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20.0],
        [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
        [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100.0],
        [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
    }),
    {
        {"CustomerID", Order.Ascending},
        "OrderID"
    }
)

Output

Table.FromRecords({
    [OrderID = 1, CustomerID = 1, Item = "Fishing rod", Price = 100],
    [OrderID = 2, CustomerID = 1, Item = "1 lb. worms", Price = 5],
    [OrderID = 6, CustomerID = 1, Item = "Tackle box", Price = 20],
    [OrderID = 3, CustomerID = 2, Item = "Fishing net", Price = 25],
    [OrderID = 4, CustomerID = 3, Item = "Fish tazer", Price = 200],
    [OrderID = 5, CustomerID = 3, Item = "Bandaids", Price = 2],
    [OrderID = 7, CustomerID = 5, Item = "Bait", Price = 3.25],
    [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100],
    [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
})
