I am having some difficulty getting the results that I am looking for out of my access query (SQL below).  I have a date field and a time field that show when a trouble ticket was opened, what I want to do is some how figure out how long in DECIMAL HOURS (hour and a half = 1.5 for example) a trouble ticket has been open at the time the report is run.  I was trying to add the date + the time field and subtract this from the NOW() function but am not having any luck.

VBA or SQL either one will work for me, I just need to get the right output, this is the last query that is run prior to the exportation of the results to excel via an automation macro, currently this all happens without any manual input and I want to keep it that way, I just need to add one last field.

Any help would be much appreciated.

Thanks
SELECT DISTINCT TOP 25 tbl_Top_25_main.[TKT#], tbl_Top_25_main.[DATE REC], tbl_Top_25_main.[TIME REC], tbl_Top_25_main.[REPORT CAT], tbl_Top_25_main.[RESPONSIBLE MCO], tbl_Top_25_main.[CURRENT STATUS]

FROM tbl_Top_25_main

WHERE tbl_Top_25_main.[CURRENT STATUS] = (SELECT MAX(t2.[CURRENT STATUS]) FROM tbl_Top_25_main t2 WHERE tbl_Top_25_main.[TKT#] = t2.[TKT#])

GROUP BY tbl_Top_25_main.[TKT#], tbl_Top_25_main.[DATE REC], tbl_Top_25_main.[TIME REC], tbl_Top_25_main.[REPORT CAT], tbl_Top_25_main.[RESPONSIBLE MCO], tbl_Top_25_main.[CURRENT STATUS]

HAVING (((tbl_Top_25_main.[CURRENT STATUS]) Is Not Null))

ORDER BY tbl_Top_25_main.[DATE REC], tbl_Top_25_main.[TIME REC];

Hi jclem1,

You have 2 fields, .[DATE REC] &.[TIME REC], they should really be one field that has datatype Date/Time.
Can you tell us what Datatype the .[TIME REC] has & give examples of the values.

Date and Time are both text values at the moment but I can change them to whatever I need to.  

DATE REC      TIME REC
01/17/09      11:44

Before you start you should really change them to one field of type Date/Time
