SQL前一天、前一個月、前一年寫法

前一天：

SELECT * FROM [tb]
WHERE [日期字段] BETWEEN
DATEADD(DAY,-1,CONVERT(VARCHAR(8),GETDATE(),112)) AND DATEADD(MILLISECOND,-2,CONVERT(VARCHAR(8),GETDATE(),112))

上一個月：

SELECT * FROM [tb] WHERE [日期字段] BETWEEN
DATEADD(MONTH,-1,DATEADD(DAY,1-DAY(GETDATE()),CONVERT(VARCHAR(8),GETDATE(),112)))
AND
DATEADD(MILLISECOND,-2,DATEADD(DAY,1-DAY(GETDATE()),CONVERT(VARCHAR(8),GETDATE(),112)))

上一年：
SELECT * FROM [tb] WHERE [日期字段]
BETWEEN DATEADD(YEAR,-1,DATEADD(DAY,1-DATEPART(dayofyear,GETDATE()),CONVERT(VARCHAR(8),GETDATE(),112)))
AND DATEADD(MILLISECOND,-2,DATEADD(DAY,1-DATEPART(dayofyear,GETDATE()),CONVERT(VARCHAR(8),GETDATE(),112)))
