Question

Calculate total empoyee days (as of present) that have elapsed for each month in a FY

Hello, everyone,

I'm running CF server connecting to an Oracle (11g)  db.

I have a table that keeps track of projects (past, present, future) and need a way to sum the days for each project, for each month, that have happened.

For example.

ID   - Name          -   Start -   Stop  - Employees
001 Project A      01-Oct-14 31-Dec-14       8
002 Project B      06-Feb-15 21-Feb-15       9
003 Project C      30-Oct-14 29-Nov-14       3
004 Project D      26-Dec-14 16-Apr-15      21

I'm trying to create an overview where the display will have the months of a Fiscal Year go across the page, indicating the number of employee days for each project that have elapsed. (NOT counting the current day).  New requirement: To make matters even more complex, there is a related table for the employees showing what dates they actually started and stopped (not every employee starts on day 1 and ends on the last day.. some start a day or two after the project start, etc.)

I'm not wrapping my head around this, for some reason. Mental block. Any ideas?

Someone in another forum suggested a PIVOT.  That's above my paygrade (I have never used PIVOT, don't understand how it works, etc.)

V/r,

^_^

    This may be a good start. Display by Month Year the Average and Sum Dates between Start and Stop by Project.

    SELECT      CAST    (

          

            (CAST(MONTH(Start) AS varchar(2)) + '/01/' + CAST(YEAR(Start) AS varchar(4)))

            AS DateTime

        )

        AS DatePeriod,

        AVG(DateDiff(day, Start, Stop)) AS AverageDaysToClose,

        SUM(DateDiff(day, Start, Stop)) AS SumTotalDaysToClose,

        Name

    FROM     Projects

    GROUP BY CAST    (

            (CAST(MONTH(Start) AS varchar(2)) + '/01/' + CAST(YEAR(Start) AS varchar(4)))

            AS DateTime

        ),

        Name

    ORDER BY DatePeriod, Name

      Hi, FirstSavings,

      Thanks for replying!  I'll give that a shot as a starting point, and let you know.

      Much appreciated,

      ^_^
