使用Recursive CTE获得预期结果。

DECLARE @nYearInput AS CHAR(4)
DECLARE @start DATETIME, @end DATETIME

SET @nYearInput = '2013'  -- Change your input here

SET @start = CAST(@nYearInput AS VARCHAR) + '0401'
SET @end= CAST(@nYearInput + 1 AS VARCHAR) + '0301'

;WITH cte AS 
(
    SELECT dt = DATEADD(DAY, -(DAY(@start) - 1), @start)

    UNION ALL

    SELECT DATEADD(MONTH, 1, dt)
    FROM cte
    WHERE dt < DATEADD(DAY, -(DAY(@end) - 1), @end)
)
SELECT YEAR(dt) AS Year, month(dt) AS month
FROM cte
