Meine Firma hat eine Ansicht, die wir einige Berichte durchfüttern. Ich wurde mit dem Problem konfrontiert, dass es von einem der Manager, der den Bericht verwendet, ausging. Nach einigen Untersuchungen fand ich heraus, dass es 5 Minuten dauerte, um 93.000 Datensätze aus der gespeicherten Prozedur zurückzugeben, und 3 Minuten, um 68.000 Datensätze zurückzugeben, die eine SELECT-Anweisung aus der Sicht mit 1 WHERE-Klausel hinzufügten (für die Jahrespezifikation).Langsame Ergebnisse von Ansicht Abfrage
Nach dem Ausführen der Auswahl mit dem Ausführungsplan ging ich von 3 Minuten auf 16 Sekunden auf den 68.000 Datensätze, indem Sie einen Index, der fehlte. Ist immer noch viel zu langsam für mich in Ordnung zu sein, da dies nicht mehr als eine Sekunde oder 2 dauern sollte.
Ausführungsplan hat 84% Kosten in meinem Clustered-Index-Scan. Ich habe hier eine andere Frage gestellt und gefragt, wie sie das reduzieren und die Lösung ausprobieren können, aber das hatte keine Auswirkungen für mich. Ich bin kein DBA, sondern ein asp.net-Entwickler, daher kenne ich die kleinen Details der Indizierung und Optimierung nicht.
Die Abfrage wird dabei eine Auswahl nicht * als andere vorgeschlagen haben nicht, wie unten zu tun gesehen:
SELECT
[Customer_Type]
,[Customer]
,[Unit_Number]
,[Cert_Number]
,[Effective_Date]
,[Expiration_Date]
,[Coverage]
,[CoveragePercentThefts]

FROM
[Policy_Tracking].[dbo].[vw_Facility_Detail_Report_V4]
WHERE
Year_FTD = '2016'
würde jemand Geist mir dies helfen, erhalten eine bessere Zahl nach unten? Ich schätze die Hilfe.

Diese Ansicht ist ziemlich einfach. Kein Zweifel, das eigentliche Leistungsproblem liegt in 'vw_Facility_Detail_Report_V4'. –
@GordonLinoff danke für Ihre schnelle Antwort. Was oder wo schlägst du vor, ich schaue in die Ansicht? – ggiaquin16
Die Angabe der Definition von vw_Facility_Detail_Report_V4 würde helfen, ebenso wie der Ausführungsplan. – ZeroUltimax
