Hello SQL GURU's,

Im try the following SQL syntqx to use the AS inUse column..

Select TOP 10 Device.nDeviceID,
Device.sDisplayName,
sgroupname,
sDescription,
dPollTime,
MIN(nUsed_Min),
MAX(nused_Max),
SUM(nSize),
(CAST(SUM(nUsed_Min) AS FLOAT(2)) / CAST(SUM(nSize) AS FLOAT(2)) * CAST(AVG(100) AS NUMERIC(10, 2))) AS Inuse

from statisticalDisk

where Inuse >= 80

I get the following error:


Msg 207, Level 16, State 1, Line 28
Invalid column name 'Inuse'.

Im try to use the colomn to get only device with 80 or higher.

you need to make it into derived table and use it at next level

like

select *
from
(
Select TOP 10 Device.nDeviceID, 
Device.sDisplayName, 
sgroupname, 
sDescription, 
dPollTime, 
MIN(nUsed_Min),
MAX(nused_Max), 
SUM(nSize),
(CAST(SUM(nUsed_Min) AS FLOAT(2)) / CAST(SUM(nSize) AS FLOAT(2)) * CAST(AVG(100) AS NUMERIC(10, 2))) AS Inuse

from statisticalDisk
)t
where Inuse >= 80 


Also TOP 10 doesnt make much sense without an ORDER BY.as of now it just returns 10 random rows

select TOP 10 Device.nDeviceID,
Device.sDisplayName,
sgroupname,
sDescription,
dPollTime,
MIN(nUsed_Min) AS Minimaal_gebruik,
MAX(nused_Max) AS Maximaal_gebruik,
SUM(nSize) AS Totaal_Schijfruimte,

(CAST(SUM(nUsed_Min) AS FLOAT(2)) / CAST(SUM(nSize) AS FLOAT(2)) * CAST(AVG(100) AS NUMERIC(10, 2))) AS Ingebruik


from dbo.StatisticalDisk

left outer join dbo.StatisticalDiskIdentification on StatisticalDiskIdentification.nStatisticalDiskIdentificationID = StatisticalDisk.nStatisticalDiskIdentificationID

left outer join dbo.PivotStatisticalMonitorTypeToDevice on PivotStatisticalMonitorTypeToDevice.nPivotStatisticalMonitorTypeToDeviceID = StatisticalDiskIdentification.nPivotStatisticalMonitorTypeToDeviceID

left outer join Device on Device.nDeviceID = PivotStatisticalMonitorTypeToDevice.nDeviceID
INNER JOIN pivotdevicetogroup ON PivotDeviceToGroup.nDeviceID = Device.nDeviceID
INNER JOIN DeviceGroup ON PivotDeviceToGroup.nDeviceGroupID = DeviceGroup.nDeviceGroupID
INNER JOIN time on StatisticalDisk.dPollTime = time.PK_Date
where StatisticalDisk.dPollTime = dateadd(MM, 1, 'time')
AND DeviceGroup.sGroupName IN ('CUSTOMER')
group by Device.nDeviceID,
Device.sDisplayName,
devicegroup.sgroupname,
sDescription,
dPollTime,
nSize
order by dPollTime desc

THis the syntax full... But what your sending is not possible.
