and i want to SELECT all the 8/22/2007 dates..
how can i creates such stored procedure and make the query in C#?
One way to do it (I don't assert that it is optimal) is to select the
date as
convert(datetime,convert(varchar, @TheDate, 101), 101)
This converts the date to a varchar in the format mm/dd/yyyy (dropping
the time part), and back to datetime.
However, a Select done on that expression will not be able to use any
indexes that Sql Server might have on that column. It is therefore better,
although a little more complex, to Select ... Where column Between
@startdate and @enddate, where you would build startdate and enddate in your
C# code to be the desired date at 00:00:00 and the desired date at 23:59:59,
respectively. Your code would be similar to the following:
DateTime dateToSearch = DateTime.Now; //Test value
DateTime dateWithoutTime = dateToSearch.Date;
DateTime startDate = dateWithoutTime;
DateTime endDate = dateWithoutTime.AddSeconds(24*3600-1);
string query = "Select * from TheTable Where TheColumn Between @startDate
And @endDate";
SqlCommand cmd = new SqlCommand(query, connection);
cmd.Parameters.AddWithValue("@startDate", startDate);
cmd.Parameters.AddWithValue("@endDate", endDate);
SqlDataReader rdr = cmd.ExecuteReader(); //For instance
