SQL Month to Date

Hi
How do I convert the following SQL statement to show month to date numbers in the "Metres" column
I want to show all dates with the month to date number for each of them

SELECT [Performance].[Date] As [Date],[Performance].[Shaft], Sum([Performance].[Drilled Total]) AS Metres,[Shafts].[Target] * Count(DISTINCT [Performance].[Date]) As Target, Avg([Performance].[Drilled Total]) As [Ave M/Mach/Shift], Sum([Performance].[Delay Hours 1]) AS Delays, Sum([Performance].[DWR Hours]) AS DWR, Sum([Performance].[Standing Time]) AS [Standing Time], Sum([Performance].[Grout Hours]) AS [Grout Hours], Sum([Performance].[Concrete Redrill]) AS ReDrill, Sum([Performance].Setup) AS Setups, Sum([Performance].[Transport Hours]) as [Transport Hours], Sum([Performance].[Photographic Survey]) as [Photographic Survey], Sum([Performance].[Day Rate]) as [Day Rate], Sum([Performance].[Blank Cap]) as [Blank Cap], Sum([Performance].[Mobilise]) as [Mobilise], Sum([Performance].[Set Up Stope]) as [Set Up Stope], Sum([Performance].[Interhole Move]) as [Interhole Move], Sum([Performance].[Grouting Borehole]) as [Grouting Borehole], Sum([Performance].[Plugging]) as [Plugging], Sum([Performance].[Trp Equip UG]) as [Trp Equip UG], Cast([Shafts].[From] As Date) As [Month_Start]

 FROM [Performance] Inner Join [Shafts] On [Performance].[Shaft] = [Shafts].[Shaft] Where [Date] >= [Shafts].[From] And [Date] <= '07 Nov 2015'And [Performance].[Shaft] = 'richard air' 

GROUP BY [Performance].[Date],[Performance].Shaft,[Shafts].[From],[Shafts].[Target]

What do you mean with month to date? Do you mean todays or current month?
The metres colum is Sum([Performance].[Drilled Total]), I don't know how that relates to dates or moths.

Do you want data grouped by months instead of per day? Then GROUP BY [Performance].[Date] must be changed to a month value, eg GROUP BY datediff(Month,0,[Performance].[Date])

The start date an be anything, important is the expression is the same per month.

But most probably I misundeerstand your overall problem.

A more simple way to describe it would be:
I want each Date to show the total from the Start_date
So if 5m is drilled over three dates then you would see

10-May-2015  5
11-May-2015  10
12-May-2014  15

So you want a running sum instead of sum per date.

Then what you need is an OVER clause:

SUM([Performance].[Drilled Total]) OVER (ORDER BY something) AS [Running Total]

If you want this per month you need to PARTITION this by month, eg

SUM([Performance].[Drilled Total]) OVER (PARTITION BY datediff(Month,0,[Performance].[Date]) ORDER BY something) AS [Running Total], but you can't have larger partitions than groups and since you group by date that would lead to a sum per date anyway. Maybe you want to take away the grouping in that aspect.

Bye, Olaf.

As an example (If you have adventureworks data installed):

Select s.SalesOrderID, s.SalesOrderDetailID,
Sum(s.LineTotal) over (partition by s.SalesOrderID order by s.SalesOrderDetailID) as [running order total]
from AdventureWorks2012.Sales.SalesOrderDetail s

Open in new window


This sums the linetotal of orderdetails as running sum, reset to 0 per order by the partitioning.
