with cte as (
select '2014-03-10 08:00:00' as Dates
union all
select '2014-05-11 14:00:00'
)
select * from cte
join someTable on 1=1
OPTION (MAXRECURSION 0)
The here above SQL is outputing like a charm all hours between two dates and a field retrieved from a join with another table:
2014-03-10 02:00:00 A
2014-03-10 02:00:00 B
2014-03-10 03:00:00 A
2014-03-10 03:00:00 B
...
2014-05-11 13:00:00 A
2014-05-11 13:00:00 B
2014-05-11 14:00:00 A
2014-05-11 14:00:00 B
I would like to create a view from that but I do not manage to do it. I tried several things but without success. The following is returning : Incorrect syntax near the keyword 'OPTION'.
CREATE VIEW viewName as
with cte as (
select '2014-03-10 08:00:00' as Dates
union all
select '2014-05-11 14:00:00'
)
select * from cte
join someTable on 1=1
OPTION (MAXRECURSION 0)
You cannot specify the MAXRECURSION
option inside a view.
From http://benchmarkitconsulting.com/colin-stasiuk/2010/04/12/maxrecursion-with-a-cte-in-a-view/:
In order to make use of the MAXRECURSION option you need to first create your view without using the MAXRECURSION option:
USE AdventureWorks;
GO
CREATE VIEW vwCTE AS
--Creates an infinite loop
WITH cte (EmployeeID, ManagerID, Title) as
(
SELECT EmployeeID, ManagerID, Title
FROM HumanResources.Employee
WHERE ManagerID IS NOT NULL
UNION ALL
SELECT cte.EmployeeID, cte.ManagerID, cte.Title
FROM cte
JOIN HumanResources.Employee AS e
ON cte.ManagerID = e.EmployeeID
)
-- Notice the MAXRECURSION option is removed
SELECT EmployeeID, ManagerID, Title
FROM cte
GO
Then when you query the view include the MAXRECURSION option:
USE AdventureWorks;
GO
SELECT EmployeeID, ManagerID, Title
FROM vwCTE
OPTION (MAXRECURSION 2);</pre>
