SQL Server 2014ストアドプロシージャが遅い

Question

レシートを計算するストアドプロシージャがあります。今日まで、100,000行のデータベースで実行するまで問題はありませんでした。それは遅すぎて、少なくとも3時間稼働し、まだ完了していません。

これを最適化する方法はありますか？ここでは、コード

：

Declare @sousTotal numeric(16,2), 
    @TotalTx1 numeric(18,4), 
    @TotalTx2 numeric(18,4), 
    @TotalTx3 numeric(18,4), 
    @Taux1 numeric(18,4), 
    @Taux2 numeric(18,4), 
    @Taux3 numeric(18,4), 
    @totalEscompte numeric(16,2), 
    @totalFacture numeric(16,2), 
    @MontantPaiement numeric(16,2)

おかげで再び！

Answer 1

tbfactureDetailテーブルのIdFactureとIDCompagnieのカーディナリティに応じて、索引が存在しない場合は索引が役立ちます。

IDfactureあたり比較的少ないIdCompagnieがある場合IDFacture

CREATE NONCLUSTERED INDEX IX_NewIdx_Name 
    ON tbfactureDetail (IdFacture,IdCompagnie) 

を多くの異なる値に対するIdCompagnie多くの異なる値がある場合は、インクルード使用することができます。

CREATE NONCLUSTERED INDEX IX_NewIdx_Name 
ON tbfactureDetail (IdFacture) 
INCLUDE (IdCompagnie) 

私はこれが数学的には同じで、コードにはもう少し最適だと思います。

BEGIN TRY 

select top 1 @Taux1 = TauxTaxe1 
,   @Taux2 = TauxTaxe2 
,   @Taux3 = TauxTaxe3 
from tbFactureEntete 
where ID = @IdFacture and IDCompagnie = @IDCie 


select @sousTotal =sum(isnull(A.TotalLigne,0)) 
,  @TotalTx1 = sum(taxe1 * isnull(A.TotalLigne,0) * @Taux1/100) 
,  @TotalTx2 = sum(taxe2 * isnull(A.TotalLigne,0) * @Taux2/100) 
,  @TotalTx3 = sum(taxe3 * isnull(A.TotalLigne,0) * @Taux3/100) 
,  @totalEscompte = sum(isnull(MontantEscompte,0)) 
,  @totalFacture = 
sum(taxe1 * isnull(A.TotalLigne,0) * @Taux1/100) + 
sum(taxe2 * isnull(A.TotalLigne,0) * @Taux2/100) + 
sum(taxe3 * isnull(A.TotalLigne,0) * @Taux3/100) 
from tbfactureDetail A 
where IdFacture = @IdFacture and A.IDCompagnie = @IDCie 


select @MontantPaiement = SUM(MontantPaiement) 
from tbFacturePaiement 
where IdFacture = @IdFacture 

update tbFactureEntete 
set Total_AvantTaxe = @sousTotal 
, totalTaxe1  = @TotalTx1
