Answer 1

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

EDIT: 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
