    Query for Summing by grouping the value of Other column

    Hi,

    need help in summarizing a query based on the value on other field.

    Attached the database for your reference. database contains:-
    1. tblResponse - the data mainly get stored


    2. tblresponse Query & tblresponseTimequery - contains data from 'tblresponse' & few additional columns of calculation.
    3. QueryStatusTimecountreport - is developed based on the data under tblresponseTimequery

    Column STATUS under tblresponseTimequery contains the types of activity
    Column TIMEDiff calculates the time taken to perform the activity.

    I need to generate query which needs to sum up the time in Timediff column basis on the status under each & every users.
    Example:
    User 1-New 2-Response 3-Closure 5-Reminder
    HariRam sumofTimeDiff sumofTimeDiff sumofTimeDiff sumofTimeDiff
    Assumption sumofTimeDiff sumofTimeDiff sumofTimeDiff sumofTimeDiff

    I tried to generate the query using Dsum function with below calculation
    Dsum("TimeDiff","TblResponsetimequery","Status=""1-New""") with the 'Total' as 'Expression' but shows an error as 'Incorrect data format.....'.

    So, can someone please look into it and advise as how this query can be written to retrieve the information as required.

    Thanks in advance.

    Regards,
    Harry

    The DLookup references a field named Slot in TblTimeslot but there is no such table.

    The TurnTime function returns a string value, not a number. This can cause issues with using this value in subsequent calcs.

    Did you try a CROSSTAB query to get the matrix output?
    TRANSFORM Sum([tblresponse Query].TIMEDIFF) AS SumOfTIMEDIFF
    SELECT [tblresponse Query].AssignedTo
    FROM [tblresponse Query]
    GROUP BY [tblresponse Query].AssignedTo
    PIVOT [tblresponse Query].Status;

    TblTimeslot has been removed from the below file, as it was not in a reference.

    I was able to derive the requirement thru Crosstab. but I want to get the same output thru the query, as I will require this to merge to another queries of similar calculation.
    Is there any possibilities?

    CROSSTAB is a query. It can be joined to other queries.

    Domain aggregates can perform slowly in queries. However, this expression does work for me. Your version with the doubled quote marks also works. Don't know why it errors for you.

    Total: DSum("TimeDiff","tblResponseTimeQuery","Status='1-New'")


    Here is technique to emulate a CROSSTAB query http://www.datapigtechnologies.com/f.../crosstab.html

    Hi,

    Just tried to execute the query with the same DSUM function, but received the same error msg.
    Refer to the attachment.

    Addition to this, just tried to add a calculated column in tblresponse table, wherein able to get the time difference at the table level itself.
    TimeTaken: IIf(IsNull([AssistanceRequested]),(([EndedTime]-[StartedTime])*1440),(([AssistanceRequestedTime]-[StartedTime])+([EndedTime]-[RestartedTime]))*1440)

    But, when I use the below DSUM against the same, all the column shows the value as 900.
    Seems its totalling up all the Cells, irrespective of what is in the Status column.

    Can you plse review this as well & advise as why the DSUM function output is not as per the expected.

    Hi,
    I just used SUM IIF functions together & were able to retrieve the information as required.
    Sum(IIf([Status] = "1-New",[TimeTaken],0))

    Now I'm able to design the query as per expected.

    Hence subject issue resolved

    Thanks
