  • 0

Trying to write a query to display the current status of services in a company department. What I have written is just not working. I feel like I am going in the wrong direction.

SELECT MAX(v_StatusEvents.EventTimeStamp) as EventTimeStamp
    , MAX(v_StatusEvents.StatusTypeID) as StatusTypeID
    , v_StatusEvents.ServiceID
    , v_StatusEvents.StatusTypeDescription
    , v_StatusEvents.ServiceName
    , v_StatusEvents.CategoryName
FROM v_StatusEvents
WHERE v_StatusEvents.CategoryID = 100
    AND YEAR(v_StatusEvents.EventTimeStamp) = YEAR(getdate())
    AND MONTH(v_StatusEvents.EventTimeStamp) = MONTH(getdate())
    AND DAY(v_StatusEvents.EventTimeStamp) = DAY(getdate())
GROUP BY  v_StatusEvents.ServiceID
    , v_StatusEvents.StatusTypeDescription
    , v_StatusEvents.ServiceName
    , v_StatusEvents.CategoryName

I have three CATEGORIES: (100 – Internet, 101 – Applications, and 102 – Network).
Each CATEGORY contains SERVICES.
As an example, I have three SERVICES that belong to the CATEGORY Interenet: (50 – Internal, 51 – External, 52 – Development).
Each SERVICE will always have at least one status record for the current date.
The CURRENT STATUS will be set to one of three different STATUS TYPES values: 1 = no issue, 2 = disruption, 3 = critical.

I want to show the highest STATUS TYPE for each category for today.

Here is a sample record set for today’s date.

SeID   CatID    EventTimeStamp         SvcID  StatTypeID  
201     100     11/11/2012 12:01am     52     1     
202     100     11/11/2012 12:01am     51     1     
203     100     11/11/2012 12:01am     50     1     
204     100     11/11/2012 08:00am     51     3  
205     100     11/11/2012 10:50am     50     2     
206     100     11/11/2012 11:00am     50     1     
207     100     11/11/2012 11:25am     52     2

As you can see, there was a disruption problem with the Internal web site at 10:50m, but it was resolved at 11:00am.

There is an ongoing critical issue with the External web site that has not yet been resolved. I would like the for the query to return the value 3 because this is the highest CURRENT STATUS for a SERVICE that has not been resolved.

(If all services had “no issue”, I would expect the query to return the value 1)

Thanks,

    Ended up coming with the following solution:

    SELECT (IsNull(MAX(tblStatusTypes.StatusTypeImgURL), (SELECT tblStatusTypes.StatusTypeImgURL FROM tblStatusTypes WHERE tblStatusTypes.StatusTypeID = 1)))
    FROM tblStatusTypes
    WHERE tblStatusTypes.StatusTypeID in (

    SELECT MAX(StatusTypeID)
FROM
(   SELECT vse.StatusTypeID, vse.ServiceID, vse.EventTimeStamp
    FROM v_StatusEvents vse,
        (SELECT MAX(EventTimeStamp)AS MaxDate
            ,ServiceID
        FROM   v_StatusEvents 
        WHERE  EventTimeStamp >= Cast(Cast(CURRENT_TIMESTAMP AS DATE) AS DATETIME) 
        AND CategoryID = @CategoryID
        GROUP  BY ServiceID) MaxResults
    WHERE vse.ServiceID = MaxResults.ServiceID
    AND vse.EventTimeStamp = MaxResults.MaxDate
) MaxStatusType )
