: Wechsel zu Statisticsdata_Dynamic_Consolidation Skript

Question

Wo soll ich die folgenden Änderungen an meinem Skript setzen:

1. Triggerdate sollte gestern Datum werden (falls das Skript auf 6. Juni Mitternacht läuft, Triggerdatum 2017.06.05 sein sollte)
2. Die Daten sollten basierend auf der Differenz in Min. Jun. 5 und Max. Jun. 5 berechnet werden.

Das ist mein Skript:

Answer 1

Per SQL Server .. Versuchen:

für die erste Frage:

Select Convert(varchar(10), DATEADD(month, -1, GETDATE()), 120) 

120 in der letzten ist das Datumsformat in der folgenden Reihenfolge: yyyy-MM-dd

Select Convert(varchar(2), DATEADD(month, -1, GETDATE()), 101) 

oben Conversion nur Monat zurückkehren:

Um nur das Datum zu erhalten, können Sie die Größe der Varchar in Convert-Funktion mit einem anderen Format, wie zum Beispiel ändern. Andere Formate finden Sie unter Date Time Formats.

für zweite Frage:

In Ihrem Fall: Wählen DATEDIFF (Stunde, @startDateTime, @endDateTime)

hour repräsentiert die Zeit der Maßnahme, die Sie über

Für Detailinformationen zurückkehren möchten DateDiff Siehe auch: Detailed Answer for DATEDIFF
