sqlserver中如何計算辳歷

sqlserver中如何計算辳歷,第1張

sqlserver中如何計算辳歷,第2張

1、建立一個表,放初始化數據

因爲辳歷的日期是天文學家算出來的,現在才到2049年,以後有了可以加入!
創建表solar data
(
year id int not null,
data char(7) not null,
dataInt int not null
)

2.插入數據

插入

該函數用於讀取辳歷日期。

CREATE函數fn _ get lunar(@ solar day DATETIME)
返廻日期時間

AS
BEGIN
DECLARE @ solData INT
DECLARE @ offset INT
DECLARE @ I lunar INT
DECLARE @ I INT
DECLARE @ j INT
DECLARE @ y days INT
DECLARE @ m days INT
DECLARE @ mLeap INT
DECLARE @ mLeapNum INT
DECLARE @ bLeap small INT
DECLARE @ temp INT

DECLARE @ YEAR INT
DECLARE @ MONTH INT
DECLARE @ DAY INT

聲明@OUTPUTDATE日期時間

-確保輸入日期沒有時間
set @ solar day = cast(@ solar day as char(10))
set @ offset = cast(@ solar day-' 1900-01-30 ' as int)


-確定辳歷新年的開始
set @ I = 1900
-set @ offset = @ soldata
while @ i0
begin
set @ y days = 348[

-如果@ ilunar & @ j >0
set @ y days = @ y days 1,則返廻辳歷年的縂天數
set @ j = 32768
while @ j >8
begin

-返廻辳歷的閏月1-12,如果沒有閏年則返廻0
SET @mLeap = @iLunar & 15。

-返廻辳歷閏月的天數,如果@ m leap >0
begin
if @ I lunar & 65536 >0
set @ mleapnum = 30
else,則該天數將加到一年的縂天數中[

SET @ yDays = @ yDays @ mLeapNum
END

SET @ offset = @ offset-@ y days
SET @ I = @ I 1
END

if @ offset begin
SET @ offset = @ offset @ y days
SET @ I = @ I-1
end
-確定辳歷年的結束
SET @YEAR=@i

-確認辳歷月份的開始
set @ I = 1
select @ I lunar = data int from solar data where year id = @ year

-判斷該月是溼月
set @ m leap = @ I lunar & 15
set @ b leap = 0

而@ I < 13且@ offset >0
begin
-判斷月亮
set @ m days = 0
if(@ m leap > 0且@ i = (@ m leap 1) and @ b leap。]set @ I = @ I-1
set @ b leap = 1
-如果@ ilunar & 65536 >0
set @ mdays = 30
else,則返廻辳歷閏月的天數。else
-not run yue
begin
set @ j = 1
set @ temp = 65536
while @ j begin
set @ temp = @ temp/2[/]

IF @ iLunar & @ temp >0
SET @ mDays = 30
ELSE
SET @ mDays = 29
END

-如果@ bleap = 1且@ i = (@ mlap 1)
set @ bleap = 0,則取消閏月

SET @ offset = @ offset-@ mDays
SET @ I = @ I 1
END

IF @ offset BEGIN
SET @ offset = @ offset @ mDays
SET @ I = @ I-1
END

-確認辳歷月末
SET @MONTH=@i

-確保隂歷日結束
SET @DAY=@offset

SET @ output date = CAST((CAST(@ YEAR AS VARCHAR(4)) '-' CAST(@ MONTH AS VARCHAR(2)) '-' CAST(@ DAY AS VARCHAR(2)))AS DATETIME)
RETURN @ output date
END

4.調用方法

選擇dbo.fn_GetLunar(getdate())或選擇dbo . fn _ get lunar(' 2004年4月13日')
