Question : ms sql calculation in wrong

I have the following sql statement which is giving a wrong result for may and july. april and jun are correct.  the only difference is that there are two records for may and jul.


SELECT top 12 CONVERT(VARCHAR, DATEADD(month, DATEDIFF(month, 0, fldStart), 0), 106) as fldDate ,sum([fldClosedOnTime]),sum([fldassignedclosed]), SUM([fldClosedOnTime]/[fldassignedclosed])  FROM [KPI].[dbo].[viewSAPrepProjectBSC] where DATEADD(month, DATEDIFF(month, 0, fldStart), 0) <= DATEADD(month, DATEDIFF(month, 0, getdate()), 0) group by DATEADD(month, DATEDIFF(month, 0, fldStart), 0) order by DATEADD(month, DATEDIFF(month, 0, fldStart), 0)

fldDate             (No column name)      (No column name)      (No column name)
01 Apr 2010      19                              64                              0.296875
01 May 2010      19                              128                              0.296875
01 Jun 2010      24                              64                              0.375
01 Jul 2010      40                              119                              0.704261363636364


the raw data is
fldAssignedClosed    fldClosedOnTime     fldStart
55                                31                                2010-07-28 00:00:00.000      
64                                9                                2010-07-12 00:00:00.000      
64                                24                                2010-06-23 00:00:00.000      
64                               15                                2010-05-26 00:00:00.000      
64                               4                                2010-05-05 00:00:00.000

Answer : ms sql calculation in wrong

You mean on the last column? Do you mean


SELECT top 12 CONVERT(VARCHAR, DATEADD(month, DATEDIFF(month, 0, fldStart), 0), 106) as fldDate ,sum([fldClosedOnTime]),sum([fldassignedclosed]), 1.0*SUM([fldClosedOnTime])/Sum([fldassignedclosed])  FROM [KPI].[dbo].[viewSAPrepProjectBSC] where DATEADD(month, DATEDIFF(month, 0, fldStart), 0) <= DATEADD(month, DATEDIFF(month, 0, getdate()), 0) group by DATEADD(month, DATEDIFF(month, 0, fldStart), 0) order by DATEADD(month, DATEDIFF(month, 0, fldStart), 0)
