Question

In a SELECT command to my SQL Server 2005 database, I need to convert the OrderDelDateTime column (which is in datetime format) to a date format so that I can select all rows with today’s date, regardless of the time.

Here is what I’ve got:

cmd = New Data.SqlClient.SqlCommand("SELECT * FROM [Orders] where [OrderDelDateTime] = '" + Now.Date + "'", conn)

Obviously this returns zero results because 11/30/2012 5:30:00 PM (in db) doesn’t equal Now.Date (11/30/2012).

I’m using VB.Net.

Answer 1

Make your query like this:

select *
from Orders
where OrderDelDateTime between @Date1 and @Date2

Then from C#, pass the following two parameters:

cmd.Parameters.AddWithValue("@Date1", Now.Date);
cmd.Parameters.AddWithValue("@Date2", Now.Date.AddDays(1).AddMilliseconds(-1));
