Question

Why dynamic SQL does not work ??

code in C# :

 this.DataAccess.AddParametr("@where","WHERE ta.IdMoinRef in(112,113,115)");

code in sqlServer:

ALTER Procedure [dbo].[sp_tblAsnad_SelectAllForReport]
@where nvarchar(max)
As
Begin                                       
Select
        ta.IdMoinRef,
        ta.IdTafzeliRef,
        ta.ShHesab,
        ta.Bd,
        ta.Bs,
        ta.ShSnd,
        ta.AtfSnd,
        ta.DateSnd,
        mo.Hmoin,
        co.Hcol,
        gr.Hgroup,
        co.IdGroupRef,
        mo.IdColRef
    From tblAsnad as ta
    inner join tblMoin as mo on ta.IdMoinRef=mo.IdMoin
    inner join tblCol as co on mo.IdColRef=co.IdCol
    inner join tblGroup as gr on co.IdGroupRef=gr.IdGroup
    exec(@where)
End

You’re confused. You need to encapsulate your entire statement into a command. You’re attempting to execute one query and then an additional query. You need to parse your main query together with your parameter, e.g.

DECLARE @sql VARCHAR(1000)
SET @sql = "SELECT ... " + @where -- Your full query.
exec(@sql)
