Hi:
Please, is there any way to summarize this sql command below to show
me only one data per day ?
Actually it´s show me 24 data ( one per hour):



SELECT TOP 10000 Nodes.Caption AS NodeName,
APM_AlertsAndReportsData.ComponentName AS Component_Name,
APM_ResponseTime.StatisticData AS StatisticsData,
APM_ResponseTime.DateTime AS DateTime

FROM
(Nodes INNER JOIN APM_AlertsAndReportsData ON (Nodes.NodeID =
APM_AlertsAndReportsData.NodeId)) INNER JOIN APM_ResponseTime ON
(APM_AlertsAndReportsData.ComponentId = APM_ResponseTime.ComponentID)


WHERE

( DateTime >= dateadd(mm,datediff(mm,0,getdate())-1,0) AND DateTime
<dateadd(mm,datediff(mm,0,getdate()),0) )


AND
(
(Nodes.Caption = 'SERV-ABP3') AND
(
(APM_AlertsAndReportsData.ComponentName = 'swap')

))



serv-abp3 swap 1 2009-11-26 00:00:00.000
serv-abp3 swap 1 2009-11-26 01:00:00.000

It is not very clear how you want to group your data (for example, do you want to summarize statistic data). Here is
generic form to get rid of the time portion (by setting it to midnight for all dates) and group by all columns, which
will eliminate the duplicate lines. You may want to use the SUM aggregate function for the StatisticData column and
remove it from the GROUP BY clause.

SELECT TOP 10000 Nodes.Caption AS NodeName,
APM_AlertsAndReportsData.ComponentName AS Component_Name,
APM_ResponseTime.StatisticData AS StatisticsData,
DATEADD(DAY, DATEDIFF(DAY, 0, APM_ResponseTime.[DateTime]), 0) AS [Date]
FROM Nodes
INNER JOIN APM_AlertsAndReportsData
ON Nodes.NodeID = APM_AlertsAndReportsData.NodeId
INNER JOIN APM_ResponseTime
ON APM_AlertsAndReportsData.ComponentId = APM_ResponseTime.ComponentID
WHERE [DateTime] >= DATEADD(mm, DATEDIFF(mm, 0, CURRENT_TIMESTAMP)-1, 0)
AND [DateTime] < DATEADD(mm, DATEDIFF(mm, 0, CURRENT_TIMESTAMP), 0)
AND Nodes.Caption = 'SERV-ABP3'
AND APM_AlertsAndReportsData.ComponentName = 'swap'
GROUP BY Nodes.Caption,
APM_AlertsAndReportsData.ComponentName,
APM_ResponseTime.StatisticData,
DATEADD(DAY, DATEDIFF(DAY, 0, APM_ResponseTime.[DateTime]), 0);

To show data once per day:

SELECT Nodes.Caption AS NodeName,
APM_AlertsAndReportsData.ComponentName AS Component_Name,
AVG(APM_ResponseTime.StatisticData) AS StatisticsData,
convert(char(10), APM_ResponseTime.DateTime, 112) AS DateTime
FROM ...
GROUP BY Nodes.Caption, APM_AlertsAndReportsData.ComponentName,
convert(char(10), APM_ResponseTime.DateTime, 112)

To group by the hour, just change char(10) to char(13)
