有人可以帮助我吗?
我有这个查询:
Use StockDataFromSella;
DECLARE @D1 DateTime
DECLARE @D2 DateTime
DECLARE @Interval FLOAT
SET @D1 = '2008-09-21T09:00:00.000'
SET @D2 = '2010-10-20T17:30:00.000'
SET @Interval = 15
;WITH
L0 AS (SELECT 1 AS c UNION ALL SELECT 1),
L1 AS (SELECT 1 AS c FROM L0 A CROSS JOIN L0 B),
L2 AS (SELECT 1 AS c FROM L1 A CROSS JOIN L1 B),
L3 AS (SELECT 1 AS c FROM L2 A CROSS JOIN L2 B),
L4 AS (SELECT 1 AS c FROM L3 A CROSS JOIN L3 B),
Nums AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0)) AS i FROM L4),
Ranges AS(
SELECT DATEADD(MINUTE,@Interval*(i-1),@D1) AS StartRange,
DATEADD(MINUTE,@Interval*i,@D1) AS NextRange
FROM Nums where i <= 1+CEILING(DATEDIFF(MINUTE,@D1,@D2)/@Interval))
,cte AS ( SELECT * ,ROW_NUMBER() OVER (PARTITION BY
Simbolo,r.StartRange ORDER BY [DataOra]) AS RN_ASC
,ROW_NUMBER() OVER (PARTITION BY Simbolo,r.StartRange ORDER BY
[DataOra] DESC) AS RN_DESC
FROM Ranges r
JOIN dbo.tbl1MinENI p ON p.[DataOra] >= r.StartRange and
p.[DataOra] < r.NextRange )
SELECT Simbolo,
MAX(CASE WHEN RN_ASC=1 THEN [DataOra] END) AS AperturaDataOra,
MAX(CASE WHEN RN_ASC=1 THEN [Apertura] END) AS [Apertura],
MAX(Massimo) Massimo,
MIN(Minimo) Minimo,
MAX(CASE WHEN RN_DESC=1 THEN [Chiusura] END) AS [Chiusura],
SUM(Volume) Volume
/*MAX(CASE WHEN RN_DESC=1 THEN [DataOra] END) AS ChiusuraDataOra*/
FROM cte
GROUP BY Simbolo,StartRange
ORDER BY AperturaDataOra
在 microsoft sql 2005 2008 中完美运行我想在 mySQL 中使用这个查询。
