Laufzeit von Stored Procedure verkürzen

[Bummi]

Clustered bedeutet dass die Daten physikalisch dem Index entsprechend sortiert werden. Eine Ausführung des Indexoptimierers, nach dem Löschen eines solchen Indexes, kann diesen auf die Idee bringen dass ein weitere Index nicht benötigt würde.

[Andidreas]

Also Clustered Indexe hatten wir noch keine erstellt!

Wir haben aber gerade testweise welche erstellt, aber keine von den getesteten brachte eine Performance Verbesserung.

D.h. die Daten werden immernoch ohne Indexe schneller ermittelt und berrechnet als mit :roll:

Sind nur zwei getrennte Indexe (einer über ALL_BRAND und ein anderer über ALL_ProductLine) vorhanden, ist die Abfrage um ein vielfaches langsamer.

Gilt das auch wenn z.B. Index1 und Index2 jeweils die Felder ALL_Brand und ALL_Productline beinhalten?

Ja, wenn die Abfrage tatsächlich beide Indexe verwendet ist das langsam.
Dazu sieht man sich am besten den Ausführungsplan an.
Es ist nicht nur wichtig das die in der Bedingung verwendeten Felder im enthalten sind, diese sollten auch an erster Stelle im Index definiert sein.

Dann sind entweder die Indexe für die Abfragen nicht geeignet oder die Abfragen ungünstig formuliert.
Bitte mal beides posten.

Jede deiner Abfragen verarbeitet alle Datensätze der gesamten Tabelle und benutzt dafür aufwendige Stringfunktionen.
So wie die Abfragen jetzt formuliert sind, kann der Index nicht genutzt werden.

In #42 und #49 sind meine Vorschläge, wie man die Abfragen übersichtlicher darstellen und für die Nutzung des Index optimieren kann.

Die gesamte Abfrage sieht sowieso nach FullScan aus, Index hilft da nichts.
