如何从sql动态转移到vb

我想得到一个动态的结果集,根据我找到的元素.以下是我的查询示例：

declare @til DateTime = dateadd(MINUTE, -0, getdate())
declare @fra datetime = DATEADD(MINUTE, -350, @til)

declare @title nvarchar(max) = 'test title'
DECLARE @cols AS NVARCHAR(MAX),
@query  AS NVARCHAR(MAX);

create table errors (collection_id bigint, nr smallint, position smallint, stamp datetime)
create table t (collection_id bigint, collection_name nvarchar(max), nr smallint, [status] smallint, stamp datetime)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(errors.position)
                      from t t
                        left join errors on errors.collection_id = t.collection_id and errors.nr = t.nr
                        where t.Status = 4 and errors.Stamp > @fra and t.collection_name = ''' + @title + ''' and errors.collection_id is not null
                      FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') , 1, 1, '');

select @cols

set @query = 'declare @til DateTime = dateadd(MINUTE, -0, getdate())
            declare @fra datetime = DATEADD(MINUTE, -350, @til)

            ;with cte as (select t.collection_name, errors.position, count(errors.Tryksag_Nedtagsfejl_Id) antal
            from t
            left join errors on errors.collection_id = s.collection_id and errors.nr = t.nr
            where t.Status = 4 and errors.Stamp > @fra and and t.collection_name = ''' + @title + '''
            group by t.collection_name, errors.position)

                SELECT collection_name, ' + @cols + ' from
                cte
            pivot
            (
                 sum(antal)
                for position in (' + @cols + ')
            ) p '

execute(@query)

到目前为止,我已经提出了一个查询,我可以在SSMS上运行,并提供我想要的输出.这将是这样的：

如何在vb.net中为我提供这个结果集？当我只是将它作为一个查询运行它不会给我结果(假设它没有看到执行的结果集)

添加了VB代码

            Dim var_fra As Short = -60
            Dim Linie As String = "Red"
