分区和max的慢查询性能问题

Question

我有一个性能不佳的查询...我做错了什么？请帮助我，它在我的系统中执行了无数次，解决后将带给我通往天堂的阶梯

我使用sp_Blitz对系统进行了检查，未发现任何致命问题

这是查询：

SELECT MAX(F.id) OVER (PARTITION BY idstato ORDER BY F.id DESC) AS id
FROM jfel_tagxml_invoicedigi F
     INNER JOIN jfel_invoice_state S ON F.id = S.idinvoice
WHERE S.idstato = @idstato
  AND S.id = F.idstatocorrente
  AND F.sequence_invoice % @number_service_installed = @idServizio
ORDER BY F.id DESC,
         F.idstatocorrente OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY;

这是查询计划

我可以私下向您发送我的系统属性

更新：进行了一些修改，它是更好，但我认为可能会更好...这是新的查询：

SELECT MAX(F.id) AS id
FROM jfel_tagxml_invoicedigi F
     INNER JOIN jfel_invoice_state S ON F.id = S.idinvoice
WHERE S.idstato = @idstato
  AND S.id = F.idstatocorrente
  AND F.sequence_invoice % @number_service_installed = @idServizio;

更新：进行了一些修改，它是更好，但我认为可能会更好...这是新的查询：

SELECT top 1 F.id as id 
FROM jfel_tagxml_invoicedigi AS F 
INNER JOIN jfel_invoice_state AS S 
ON F.idstatocorrente = S.id
WHERE S.idstato= 1 AND S.id = F.idstatocorrente 
and S.datastato > dateadd(DAY,-5,getdate())
AND F.progressivo_fattura % 1 = 0
ORDER BY S.datastato

Answer 1

数据计算是不可控制的，您可以尝试使用带有 OPTION RECOMPILE 的变量：

DECLARE @d Date
SET @d = dateadd(DAY,-5,getdate())

SELECT top 1 F.id as id 
FROM jfel_tagxml_invoicedigi AS F 
INNER JOIN jfel_invoice_state AS S 
ON F.idstatocorrente = S.id
WHERE S.idstato= 1 AND S.id = F.idstatocorrente 
and S.datastato > @d
AND F.progressivo_fattura % 1 = 0
ORDER BY S.datastato
OPTION (RECOMPILE)
