Question

I’m running the following query in SSRS. If I add declarations for the two parameters, it runs fine in SQL Management Console.

declare @EMRQuery varchar(max)
declare @CPSQuery varchar(max)

set @EMRQuery = 'select Person.ExternalId 
                    from ml.Person 
                        join ml.Obs on Person.pId = Obs.pId 
                            join ml.ObsHead on Obs.hdId = ObsHead.hdId 
                    where ObsHead.name = ''SCHOOLREGDTE'' 
                        and Obs.xId = 1.e+035
                        and Obs.change = 2 
                        and Obs.obsDate >= to_date(''' 
                            + convert(varchar(30), @DateYearStart, 120) 
                            + ''', ''YYYY-MM-DD HH24:MI:SS'')
                        and Obs.obsDate < to_date(''' 
                            + convert(varchar(30), @DateQuarterEnd, 120) 
                            + ''', ''YYYY-MM-DD HH24:MI:SS'')'

set @CPSQuery = 'select ic.ListName, count(distinct pp.patientprofileid) as PatCount
                    from PatientProfile pp
                        left join PatientInsurance pi on pp.PatientProfileId = pi.PatientProfileId
                                and pi.OrderForClaims = 1
                                and pi.Inactive <> 1
                            left join InsuranceCarriers ic on pi.InsuranceCarriersId = ic.InsuranceCarriersId
                        join OpenQuery(EMR_LIVE
                            ,  ''' + replace(@EMRQuery, '''', '''''') +
                        ''' ) Students on pp.PatientId = Students.ExternalId
                    group by ic.ListName '

exec(@CPSQuery)

However, when I plug this in to SSRS, it doesn’t register that there are any fields available to report on. How do I convince SSRS that I do have fields to work with? Thanks.

Edit: I just declared the parameters in the query, and it recognized the field names.

declare @DateYearStart datetime
declare @DateQuarterEnd datetime
set @DateYearStart = '2011-07-01'
set @DateQuarterEnd = '2012-03-31'

Of course, that errored because I was declaring the parameters twice, once as query parameters and once within the query. But, as soon as I commented out the lines above, I lost the fields again.

Someone over at the MSDN forums suggested I select into a temp table, so I replaced the final exec statement with

declare @CarrierList table (Listname varchar(200), PatCount int);
insert @CarrierList exec(@CPSQuery)
select * from @CarrierList

and it seems to be working fine now.
