推荐答案
从当前月份和年份中的特定日期选择记录的最简单方法是声明一个分配给指定日期、月份和年份的 datetime 变量，以及用变量替换查询中的 getdate() - 像这样:
The simplest way to select records from a specific day in the current month and year is to declare a datetime variable assigned to the specified day, month and year, and replace getdate() in your query with the variable - like so:
declare @date datetime
select @date = '10-Aug-2010'
Select * from client c
inner join invoice i on c.id = i.ClientID
WHERE DateDiff(dd, i.date, @date) = 0
要在当前月份的指定日期运行查询，请尝试以下操作:
To run a query for a specified day of the month in the current month, try the following:
declare @day integer
select @day = 10
Select * from client c
inner join invoice i on c.id = i.ClientID
WHERE DateDiff(dd, i.date, dateadd(dd,@day-datepart(dd,getdate()),getdate())) = 0
