c#-4.0 - 从数据库中获取当前月份日期

Question

我想从数据库中获取当前月份的周年日期，但我做不到。我的查询在下面给出，但它不起作用。

qry = "Select Anniversary_Date From Family_Information WHERE DATEADD(Year,DATEPART(Year, GETDATE()) - DATEPART(Year, Anniversary_Date),Anniversary_Date) >= GETDATE()";

Answer 1

WHERE条款

SELECT...FROM...WHERE MONTH(now())=MONTH(GETDATE()) AND YEAR(now())=YEAR(GETDate())

应该工作 - 本月的周年纪念日。我不确定GETDATE()它是什么？

Answer 2

怎么样

SELECT Anniversary_Date
FROM Family_Information
WHERE ((DATEPART(Year, GETDATE()) = DATEPART(Year, Anniversary_Date)
AND (DATEPART(Month, GETDATE()) = DATEPART(Month, Anniversary_Date))

Answer 3

尝试这个 ;

 qry = "SELECT Anniversary_Date
FROM Family_Information
WHERE ((DATEPART(Year, GETDATE())) = DATEPART(Year, Anniversary_Date)
AND    (DATEPART(Month, GETDATE())) = DATEPART(Month, Anniversary_Date))" ;
