I am using Access 2003 and have a query or report problem. The file is a 4 field history file for project issues with a record created when the Status changes. The fields are PrimKey, IssueID, Status, DateTime. I need to query to calculate how many days the Issue was in a certain state. So basically take the Date Time of one entry and calculate the number of days between the next entry for that Issue number. I am trying to do this in Access and not use VB (not a vb programmer) but I could if thats the only way.

How to Calculate the length in days of a status in a history file
- Thread starter sccses
- Start date
Something like this ?
SELECT A.IssueID, A.Status, A.DateTime, B.Status, B.DateTime, (B.DateTime - A.DateTime) AS CountOfDays
FROM yourTable A INNER JOIN yourTable B
ON A.IssueID = B.IssueID AND A.DateTime < B.DateTime
Hope This Helps, PH.
