Когда я пытаюсь выполнить более сложный SQL-запрос на странице ASP, я получаю эту ошибку:

операция не разрешена, когда объект закрыт

Когда я запускаю этот код, он работает:

...
sql = "SELECT distinct team FROM tbl_teams"
rs.open sql, conndbs, 1, 1
...

Но когда я запускаю этот код (и этот код работает, если я запускаю его в Microsoft SQL Server Management Studio), я получаю сообщение об ошибке ...

...
sql = "DECLARE     @cols AS NVARCHAR(MAX),     @query  AS NVARCHAR(MAX),     @orderby nvarchar(max),     @currentYear varchar(4)  select @currentYear = cast(year(getdate()) as varchar(4))  select @cols   = STUFF((SELECT  ',' + QUOTENAME(year([datefrom]))            from tbl_teams            group by year([datefrom])            order by year([datefrom]) desc             FOR XML PATH(''), TYPE             ).value('.', 'NVARCHAR(MAX)')         ,1,1,'')  select @orderby = 'ORDER BY ['+cast(year(getdate()) as varchar(4)) + '] desc'  set @query = 'SELECT team, Won = [1],                 Lost=[2], Draw = [3]' + @cols + ', Total             from             (               select                 team,                 new_col,                 total                from               (                 select team,                   dt = year([datefrom]),                   result,                   total = count(*) over(partition by team)                 from tbl_teams               ) d               cross apply               (                 select ''dt'', dt union all                 select ''result'', case when dt = '+@currentYear+' then result end               ) c (old_col_name, new_col)             ) x             pivot             (                 count(new_col)                 for new_col in ([1], [2], [3],' + @cols + ')             ) p '+ @orderby  exec sp_executesql @query"

Это лучший обзор запроса:

DECLARE 
    @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),
    @orderby nvarchar(max),
    @currentYear varchar(4)

select @currentYear = cast(year(getdate()) as varchar(4))

select @cols 
  = STUFF((SELECT  ',' + QUOTENAME(year([datefrom])) 
           from tbl_teams
           group by year([datefrom])
           order by year([datefrom]) desc
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @orderby = 'ORDER BY ['+cast(year(getdate()) as varchar(4)) + '] desc'

set @query = 'SELECT team, Won = [1], 
                Lost=[2], Draw = [3]' + @cols + ', Total
            from 
            (
              select 
                team,
                new_col,
                total  
              from
              (
                select team, 
                  dt = year([datefrom]),
                  result,
                  total = count(*) over(partition by team)
                from tbl_teams
              ) d
              cross apply
              (
                select ''dt'', dt union all
                select ''result'', case when dt = '+@currentYear+' then result end
              ) c (old_col_name, new_col)
            ) x
            pivot 
            (
                count(new_col)
                for new_col in ([1], [2], [3],' + @cols + ')
            ) p '+ @orderby

exec sp_executesql @query

Нужно ли выполнять запрос по-другому или что не так с этим кодом?
