SQL Serverで高速なストアドプロシージャを作成しますか？

私はいくつかのテーブルに格納されている500000以上の行が必要です。私のロジックですべての行を取得する。 この状況では、SQL Serverブラウザで正常に実行されるストアドプロシージャを作成しますが、C＃コードから実行するとタイムアウト例外が発生しました。SQL Serverで高速なストアドプロシージャを作成しますか？

誰でも私のストアドプロシージャを改善する方法を提案できますか？

はい、高速にしたい場合はカーソルを使用しないでください。 –

クエリプランを見たときに確認したボトルネック –

SQL Serverの実行計画を使用して、ボトルネックを特定できます。 可能であればカーソルを使用しないようにしてください。大量のデータがある場合は、＃テーブルを作成する代わりに通常のテーブルを作成してください。

50万行を解析する場合、カーソルは非スターターです。これはあらゆる種類の問題を引き起こし、データが大きくなるにつれて、それはより遅くなり、遅くなります。より良いパフォーマンスを達成するにはいくつかの方法があります。すなわちではなく、あなたの一時テーブルに挿入する - すなわち選択バッチにできるだけ多くのデータを取得するSQLジョブ

2）を使用して、スナップショットテーブルにデータを平坦化 -

1）可能な場合は、一晩のデータをフェッチあなたのループの行ごとに行を検索すると、特定の列に必要なすべてのデータを取得するクエリを実行することができます。

3）これを一晩で行うことができず、常にこのようにしなければならない場合は、ディスクリートなストアドプロシージャとC＃コード内からのループに変換します。そのようにして、ユーザーにフィードバックを提供することができます。おそらくプログレスバーの形になります。これはタイムアウトではなく、ユーザーが何かが計算されていることを知っていればどれくらい時間がかかりますか、彼らはどれくらい待たなければならないかを大まかに知っています。をしたい。

ここにはいくつかの問題があります。適切に書かれているように、この手順はインデックスに応じて約15秒で快適に実行する必要があります。

バルク処理でカーソルを使用できるのは、バルクプロセスでの更新のパーティション分割だけです。つまり、すべてのレコードを更新するために反復処理を必要とするカーソルを使用しないでください。全体の手順は50万回繰り返す必要があり、それは非常に遅くなるでしょう。 tempテーブルを使用してデータを挿入し、そのテーブルを使用して更新を実行します。以下のコードに示すように、一時索引付きの一時表を索引付けすることは可能です。テンポラリテーブルとライブテーブルの両方について、WHERE句で使用されているフィールドがインデックスに登録されていることを確認します。

CREATE TABLE #Temp2 (
    ProductionTracingUnitID int, 
    OrderID int, 
    OrderType smallint,

CREATE NONCLUSTERED INDEX #IX_Temp2_2 ON #Temp2(OrderID) 
CREATE NONCLUSTERED INDEX #IX_Temp2_3 ON #Temp2(ProductID) 

DECLARE @SQL as varchar(MAX) 
SET @SQL=

    SELECT ProductionTracingUnitID,OrderID,OrderType,ProductID,DyeingOrderQty,JobOrderQty,ProductionPipeLineQty,ProductionFinishedQty,BuyerID,FactoryID,ProductionGraceQty, 
     WeightLossGainQty,RateInLBS,ProductionLossQty,ActualDeliveryQty,ReadyStockInhand,ColorName,LabLabDipID,ReturnQty,EWYDLRelabNo,EWYDLColorNo,ShadeFromOrder 
    FROM ProductionTracingUnit '[email protected] 
INSERT INTO #Temp2 (ProductionTracingUnitID, OrderID, OrderType, ProductID, DyeingOrderQty, JobOrderQty, ProductionPipeLineQty, 
     ProductionFinishedQty, BuyerID, FactoryID, ProductionGraceQty, WeightLossGainQty, RateInLBS, ProductionLossQty, ActualDeliveryQty, 
     ReadyStockInhand, ColorName, LabLabDipID, ReturnQty, EWYDLRelabNo, EWYDLColorNo, ShadeFromOrder) 
EXEC (@SQL)

次に、一括処理を行う場合は、行ごとに実行する必要があるサブクエリの使用を避けてください。

SELECT @LCID=ISNULL(ExportLCID,0), @LCNo=ISNULL(ExportLCNo,''),@AmendmentStatus=AmendmentStatus,@ExportLCValue=Amount 
FROM ExportLC e, [PI] p, Job j 
WHERE e.ExportLCID = p.LCID 
AND p.PIID = j.PIID 
AND j.JobID = @OrderID

カーソルを使用せずに手順を書き換え、これはより多くなります：

SELECT @LCID=ISNULL(ExportLCID,0), @LCNo=ISNULL(ExportLCNo,''),@AmendmentStatus=AmendmentStatus,@ExportLCValue=Amount 
FROM ExportLC WHERE ExportLCID =(SELECT LCID FROM [PI] WHERE PIID=(SELECT PIID FROM Job WHERE [email protected]))

このように、参加すると言い換え考えてみましょう：次の行は、時代の最高の状態で、非常に遅くなります線に沿って：

UPDATE #Temp2 SET LCID = ISNULL(ExportLCID, 0), LCNo = ISNULL(ExportLCNo, 0), ... 
FROM #Temp2 t, ExportLC e, [PI] p, Job j 
WHERE e.ExportLCID = p.LCID 
AND p.PIID = j.PIID 
AND j.JobID = t.OrderID

あり、このすべての作業を取得するために仕事のかなりのビットがある、と私はそのような化合物のプロセスのためのテスト環境を作成することは困難です。しかし、私はこれがあなたに十分に進むべきだと思う。あなたが立ち往生したら教えてください。
