Table.Sort

Σύνταξη

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

Πληροφορίες

Ταξινομεί τη table χρήση της λίστας με ένα ή περισσότερα ονόματα στηλών και προαιρετικά comparisonCriteria στη φόρμα { { col1, comparisonCriteria }, {col2} }.

Επειδή Power Query μερικές φορές απενεργοποιεί ορισμένες λειτουργίες στο παρασκήνιο προελεύσεων δεδομένων (γνωστές ως "αναδίπλωση") και επίσης ορισμένες φορές βελτιστοποιεί ερωτήματα παραλείποντας λειτουργίες που δεν είναι απολύτως απαραίτητες, γενικά δεν υπάρχει εγγύηση για τον τρόπο ταξινόμησης των γραμμών με πανομοιότυπες στήλες ταξινόμησης. Για παράδειγμα, δεν μπορείτε να υποθέσετε ότι η πρώτη γραμμή με ένα μοναδικό σύνολο τιμών στήλης θα ταξινομηθεί πρώτη. Εάν θέλετε η σειρά ταξινόμησης να συμπεριφέρεται προβλέψιμα, πρώτα κάντε buffer στον πίνακα χρησιμοποιώντας τη συνάρτηση Table.Buffer.

Παράδειγμα 1

Ταξινομήστε τον πίνακα στη στήλη "OrderID".

Χρήση

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"}
)

    [OrderID = 8, CustomerID = 5, Item = "Fishing Rod", Price = 100],
    [OrderID = 9, CustomerID = 6, Item = "Bait", Price = 3.25]
})

Παράδειγμα 2

Ταξινομήστε τον πίνακα στη στήλη "OrderID" σε φθίνουσα σειρά.

Παράδειγμα 3

Ταξινομήστε τον πίνακα στη στήλη "CustomerID" και, στη συνέχεια, "OrderID", με το "CustomerID" σε αύξουσα σειρά.
