推薦答案
從當前月份和年份中的特定日期選擇記錄的最簡單方法是聲明一個分配給指定日期、月份和年份的 datetime 變量，以及用變量替換查詢中的 getdate() - 像這樣:
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
要在當前月份的指定日期運行查詢，請嘗試以下操作:
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
