Question

I have a project in which I need to save the return value of a stored procedure.

declare @query_bereich nvarchar(500)

SET @query_bereich = 'select bereich' + convert(varchar(2), @bereich) +
                     ' from ImpArtGruppe where Artikelnummer = ' + @artnum 

set @artgrp = (EXEC sp_executesql @query_bereich)
select @artgrp = ISNULL(@artgrp, '')
select @artgrp

Now the problem I’m having is, that the return value is always 0. I guess this is by default because in another scenario the would be a restulset that can have more than one value. But in my case I have made sure the the query always returns only the one.

I have also tried foillowing code I found on google:

EXEC @artgrp = sp_executesql @query_bereich

But this did also not work.

Can anyone help me with this?

There’s no stored procedure in your example code. It looks like you are building a dynamic T-SQL query, and want to store the result from that.

Here’s one way, using sp_executesql, and assuming the type of @artgrp is varchar(50):

declare @query_bereich nvarchar(max)
set @query_bereich = 'select @artgrp = bereich' + convert(varchar(2),@bereich) +
    ' from ImpArtGruppe where Artikelnummer = ''' + @artnum + ''''
declare @artgrp varchar(50)
exec sp_executesql @query_bereich, '@artgrp varchar(50) output', @artgrp output
