Sql-server – How to improve query performance

index-tuningperformancequery-performancesql server

I have a query that executes very often on our system and there is no option to change the query text. Are there any suggestions on what could be done? Any help would be appreciated.
The query:

SELECT TOP 100 A126.DocID FROM [Документы] A126 WITH ( NOLOCK ) LEFT JOIN [Функция] A362JTA126_1 WITH ( NOLOCK ) ON A362JTA126_1.DocID=A126.[ТипПроцесса] WHERE EXISTS (   SELECT A127.[Index]   FROM [Документы_Позиции] A127 WITH ( NOLOCK )   LEFT  JOIN   [Процесс] A144JTA127_1 WITH ( NOLOCK )   ON A144JTA127_1.DocID=A127.[ПроцессОткуда]

Best Answer

You can try to eliminate the Sort costing 21% by adding a Non Clustered index to [Документы_Позиции] that will extract all required data in the order that will match it appropriately against [Процесс] A144JTA127_1

CREATE NONCLUSTERED INDEX idx ON [Документы_Позиции]([ПроцессОткуда],[ПроцессКуда])INCLUDE([Index])

Look at this article by Erik Darling for an explanation of where the expensive sort is coming from.
