SUM(CAST(....

  • Hi to all. It has been a while since I posted. I am attempting to output a value and convert it to display a file size value in MB. I would like to round the value output then apply a WHERE clause so only records over a certain size are returned (say over 50MB).

    This is what I have (which works): I am sure there are better ways to write it 🙂

    DECLARE @User nvarchar(50)
    DECLARE @StartDate smalldatetime
    DECLARE @EndDate smalldatetime
    DECLARE @Domain NVARCHAR (10)

    SET @StartDate = '15 Dec 2021'
    SET @EndDate = '16 Dec 2021'
    SET @Domain = 'mydomain.local'
    ;

    WITH cteDataTransfer AS
    (
    SELECT
    EPName,
    NTUserName,
    ParsedUserName,
    FileSize,
    SUBSTRING (NTUserName,0,CHARINDEX('\',NTUserName)) AS Domain,
    CONVERT(DATE,TransferredDate) AS [TransferredDate],
    CAST(DATENAME(WEEKDAY,TransferredDate) AS NVARCHAR(20)) AS [Weekday],
    CAST(DATENAME(DAY,TransferredDate) AS NVARCHAR(20)) AS [Day],
    CAST(DATENAME(MONTH,TransferredDate) AS NVARCHAR(20)) AS Month,
    DATEPART(YEAR,TransferredDate) As Year
    FROM [dbo].[vDCDeviceLogs]
    INNER JOIN dbo.DeviceClass AS Dclass ON dbo.vDCDeviceLogs.DeviceClassId = Dclass.DeviceClassId
    WHERE
    [FileName] IS NOT NULL
    AND [FileName] <> ''
    AND ActionName = 'WRITE-GRANTED'
    AND TransferredDate >= @StartDate
    AND TransferredDate <= @EndDate
    GROUP BY NTUserName,ParsedUserName,TransferredDate,EPName,NTUserName,FileSize
    )
    SELECT ParsedUserName,TransferredDate,Weekday,Day,Month,Year,CONVERT(NVARCHAR(440),
    SUM(CAST([FileSize] AS NUMERIC(35,2))/1048576.0)) + ' MB' AS [FileSizeMB],
    --SUM(CAST([FileSize] AS BIGINT)/1048576.0)) + ' MB' AS [FileSizeMB],
    Domain
    FROM cteDataTransfer
    WHERE Domain = @Domain
    GROUP BY TransferredDate,ParsedUserName,Weekday,Day,Month,Year,Domain

    If I change to WHERE Domain = @Domain AND Filesize > 50000  it returns error:

    Msg 248, Level 16, State 1, Line 14

    The conversion of the nvarchar value '16520105984' overflowed an int column.

    Filesize in the table is nvarchar(440)

    Many Thanks,

    Philip

  • Looks like you need BIGINT instead of INT.

    Max for INT is 2,147,483,647

    Your value is 16,520,105,984

  • Hi. Where?

    Looks like you need BIGINT instead of INT.

    I tried:

    SUM(CAST([FileSize] AS BIGINT)/1048576.0)) + ' MB' AS [FileSizeMB]

    Kind Regards,

    Phil.

  • on your where clause - do WHERE Domain = @Domain AND convert(bigint, Filesize)  > 50000

  • ...
    (
    SELECT
    EPName,
    NTUserName,
    ParsedUserName,
    CAST(FileSize AS decimal(35,2)) AS FileSize, --<<--
    SUBSTRING (NTUserName,0,CHARINDEX('\',NTUserName)) AS Domain,
    ...

  • Thank you for your replies.

    I added: CAST(FileSize AS decimal(35,2)) AS FileSize,

    +

    WHERE Domain = @Domain AND convert(bigint, Filesize) > 50000

    That worked so many thanks.

    One last question...

    --I added
    ROUND(SUM(CAST([FileSize] AS BIGINT)/1048576.0),2)) + ' MB' AS [FileSizeMB],
    ROUND(SUM(CAST([FileSize] AS BIGINT)/1073741824.0),2) + ' GB' AS [FileSizeGB],

    This resulted in error:

    Msg 8114, Level 16, State 5, Line 14

    Error converting data type varchar to numeric.

    + ROUND did not round.

    Kind Regards,

    Phil.

    Look at what you have in those formulas and then look at the error message.  Do you think that SQL Server might just be having a problem adding the strings of MB or GB go a number and is there a way to change the number to a string?  You've gotta know there is and that you've done it before.  Give it a shot.

  • I kinda wondered why the column data needed to have 'MB' in it when the column name said 'MB'?!

    It's been a while since I've seen you around, as well.  Hope this finds you and yours safe and going strong, as well.
