i.e. keeping running counts of bugs with each status.

This is easy enough to code up using cursors, but I’m wondering if any of you SQL gurus out there can help with a query to achieve this?

Ideally for mysql, but I’m curious to see anything that will work.

    With T as
(
Select B.BugDate As MainDate, C.BugID, C.BugDate ,C.Status,row_number() over(partition by B.BugDate,C.BugID order by C.BugDate Desc) As RowNum From Bug B Cross Join Bug C where B.BugDate >=  C.BugDate Group By B.BugDate,C.BugID,C.BugDate, C.Status 
) 

Select T.MainDate ,SUM(CASE WHEN T.Status = 'OPEN' THEN 1 ELSE 0 END) As SUM_OPEN,SUM(CASE WHEN T.Status = 'RESOLVED' THEN 1 ELSE 0 END) As SUM_RESOLVED
,SUM(CASE WHEN T.Status = 'CLOSED' THEN 1 ELSE 0 END) As SUM_CLOSED
From T
where T.RowNum = 1
Group By T.MainDate
Order By T.MainDate
