I need to return 5 rows - if there is data corresponding to all 5 great - would like to return that - if not, say - only data in the table for 2 out of 5 rows - then show the first two populated with data and then 3 empty rows, etc.

Is this even possible in SQL?

sure
you can return all nulls using a left outer join
but for me to provide you with the syntax i need your table structure

Here it is
CREATE TABLE [dbo].[CM_tblContractStopLoss](

	[stopLossID] [int] IDENTITY(1,1) NOT NULL,

	[contractID] [int] NOT NULL,

	[startDate] [datetime] NULL,

	[endDate] [datetime] NULL,

	[dollarThreshold] [money] NULL,

	[billedChargesPercentage] [decimal](4, 2) NULL,

	[dollarType] [tinyint] NULL,

	[dollarNotToEceed] [money] NULL,

	[patientType] [tinyint] NULL,

you can do something like this



declare @sql nvarchar(max)

declare @param varchar(10)

declare @rows int

set @param='mis'

select @rows=count(id) from emps where dept=@param

set @sql='select name from emps where dept='+char(39)+@param+char(39)+ ' union all'

--exec sp_executesql @sql

if @rows<5

begin

declare @i int

set @i=5-@rows

while @i>0

begin

set @sql=@sql+ ' select char(13) as name  union all'

set @i=@i-1

end

end

set @sql=left(@sql,len(@sql)-9)

exec sp_executesql @sql

here is bit modified version for your own table. however you have to include remaining column, I have used only two column

declare @sql nvarchar(max)

declare @param varchar(10)

declare @rows int

select @rows=count(stopLossID) from CM_tblContractStopLoss

set @sql='select stopLossID,contractid from CM_tblContractStopLoss union all'

--exec sp_executesql @sql

if @rows<5

begin

declare @i int

set @i=5-@rows

while @i>0

begin

set @sql=@sql+ ' select NULL as stopLossID,NULL as contractid  union all'

set @i=@i-1

end

end

set @sql=left(@sql,len(@sql)-9)

print @sql

exec sp_executesql @sql

Open in new window
