Solution 1

Try

SQL

SELECT T.Taskid, A1.Short_name, A2.Short_name AS [Short-Names]
FROM TASKACTIVE T
INNER JOIN ACTVCODE A1 ON T.Activity_code_id = A1.activitycode_Type_id 
INNER JOIN ACTVCODE A2 ON T.Activity_code_id = A2.activitycode_Type_id

    from    ACTVCODE a
    inner join [TASKACTV] b on a.actv_code_id = b.actv_code_id
)
select  a.task_id, a.short_name, b.short_name as short_name1
from    cte a
inner join cte b on a.task_id = b.task_id and a.rid = b.rid-1
