View Definition Includes No Output Columns ...

hello all,

i am trying to create a view but i keep getting the error 'View definition includes no output columns or no items in the FROM clause.'

below is the select statement that's the basis of my view. the explanation i got from the F1 help of enterprise manager was ...
View definition includes no output columns or no items in the FROM clause.
A view definition must have at least one table or table-structured object in the FROM clause, and must have at least one column in the select list. The view definition is missing one or both. Modify the view definition accordingly.


query:

select
Case_CaseId,
Logged,
CAST(DATEDIFF(minute, Logged, Waiting)/60.0 AS NUMERIC(9, 2)) AS Waiting,
CAST(DATEDIFF(minute, Logged, Investigating) /60.0 AS NUMERIC(9, 2)) AS Investigating,
CAST(DATEDIFF(minute, Logged, Rejected) /60.0 AS NUMERIC(9, 2)) AS Rejected,
CAST(DATEDIFF(minute, Logged, Resolved) /60.0 AS NUMERIC(9, 2)) AS Resolved,
CAST(DATEDIFF(minute, Logged, Solved) /60.0 AS NUMERIC(9, 2)) AS Solved,
CAST(DATEDIFF(minute, Logged, Closed) /60.0 AS NUMERIC(9, 2)) AS Closed
