Another option is to use CTE[^].

For further information, please see: Using Common Table Expressions[^]
WITH common_table_expression (Transact-SQL)[^]

SQL

DECLARE @items TABLE(ItemMaster INT IDENTITY(1,1), ItemName VARCHAR(30))

INSERT INTO @items(ItemName)
VALUES ('A'), ('B'), ('C')


;WITH CTE AS
(
    SELECT 1 As NoOfDay
    UNION ALL
    SELECT NoOfDay +1 AS NoOfDay
    FROM CTE
    WHERE NoOfDay < 366
)
SELECT t2.ItemMaster, CONVERT(DATE, DATEADD(DD, t1.NoOfDay, GETDATE())) AS MyDate
FROM CTE AS t1, @items AS t2
ORDER BY t2.ItemMaster, t1.NoOfDay  
OPTION (MAXRECURSION 0)

Result:

ItemMaster  MyDate
1   2015-10-06
1   2015-10-07
1   2015-10-08
1   2015-10-09
