現在、InstrumentID には既にインデックスがありますが、このクエリは、SSMS で 2 秒かかっていた以前のクエリよりも悪いものです。
これは私が最終的に持っているものです-3つの別々のクエリ:
Declare @RecordingDateTime datetime
Select @RecordingDateTime = RecordingDateTime
From Documents d Where d.InstrumentID = @InstrumentID
Select Top 1 @PreviousInstrumentID = InstrumentID ,
@PreviousDocumentID = DocumentID ,
@PreviousCreatedByAccountID = CreatedByAccountID,
@PreviousBelongsToJurisdictionID = JurisdictionID
From Documents d
Where d.RecordingDateTime < @RecordingDateTime
Order By d.RecordingDateTime Desc
Select Top 1 @NextInstrumentID = InstrumentID ,
@NextDocumentID = DocumentID ,
@NextCreatedByAccountID = CreatedByAccountID,
@NextBelongsToJurisdictionID = JurisdictionID
From Documents d
Where d.RecordingDateTime > @RecordingDateTime
Order By d.RecordingDateTime
このクエリの期間は25、SQL プロファイラーに記載されているとおりです。
