Duplicated Rows

Hi,

I have just started developing in SQL Express in the last 2 months so still learning. The problem I’m having with my stored procedure is that I get duplicate rows in my results. The row is a duplicate in terms of column 'Job No' as when the query runs in access only one instance of each 'Job No' is returned but when I recreate the query in SQL server I get a number of rows back for the same 'Job No'? How would I go about getting just 1 instance of each 'Job No' back? With column 'Days to Date' showing the total 'Days to Date' for each Job No. Please see Ms Access results if unsure of what I’m asking.

A copy of the stored procedure is below and a sample of the out-put with Ms Access results at very bottom.

ALTER PROCEDURE [dbo].[sl_DaysDonePerJob] AS

SELECT CASE WHEN [Job No] IS NULL THEN '' ELSE [Job No] END AS [Job No], SUM([Actual Days]) AS [Days to Date], CONVERT(nvarchar(10),MIN(SessionDate),101) AS [Start Date],

CONVERT(nvarchar(10),MAX(SessionDate),101) AS [End Date],

MAX(CASE WHEN DATEPART(MM,SessionDate)=1 THEN 'Jan'

WHEN DATEPART(MM,SessionDate)=2 THEN 'Feb'

WHEN DATEPART(MM,SessionDate)=3 THEN 'Mar'

WHEN DATEPART(MM,SessionDate)=4 THEN 'Apr'

WHEN DATEPART(MM,SessionDate)=5 THEN 'May'

WHEN DATEPART(MM,SessionDate)=6 THEN 'Jun'

WHEN DATEPART(MM,SessionDate)=7 THEN 'Jul'

WHEN DATEPART(MM,SessionDate)=8 THEN 'Aug'

WHEN DATEPART(MM,SessionDate)=9 THEN 'Sep'

WHEN DATEPART(MM,SessionDate)=10 THEN 'Oct'

WHEN DATEPART(MM,SessionDate)=11 THEN 'Nov'

WHEN DATEPART(MM,SessionDate)=12 THEN 'Dec' END) AS 'End Month'

FROM Sessions

GROUP BY [Job No], Sessions.SessionDate

ORDER BY [Job No]

Results in SQL Server Express

'Job No' 'DaystoDate' 'Start Date' 'End Date' 'End Month'

Not being an expert by any means, my hunch is that you should set up the first column as a primary key. It will never allow duplicate values after that. It will take you a second to do it in the SQL database table. Right click on the column name in designer. It may not eliminate the problem completely in a sense that there might be a bug in your code that does it. At least you will get an error message from the server protesting the fact that somebody is sending duplicates to it. It will be a cue for you where to look.|||Cheers Alex will give it a go.
