Insert current datetime based onclick - asp.net

Question

I am currently trying to store datetime in the database. The idea is when onclick on the button, the database will store the current datetime in the database.
I have tried some methods but they prompt me with this error:
"Incorrect syntax near '26/6/2013 00:00:00'"
This is my codes:
con.Open();
query = "INSERT INTO dbo.url_map (long_url, expiry_date) Values ('" + tbLongURL.Text + "' , '" + DateTime.Today + "')";
SqlCommand cmd = new SqlCommand(query, con);
cmd.Parameters.AddWithValue("#long_url", tbLongURL.Text);
cmd.Parameters.AddWithValue("#expiry_date", DateTime dt = DateTime.ParseExact(DateTime.Today.ToString(), "dd/MM/yyyy h:mm:ss tt", CultureInfo.InvariantCulture));
cmd.ExecuteNonQuery();
what is wrong with the way i add the date time?
Any help will be greatly appreciated.

Answer 1

Corrected query-
query = "INSERT INTO dbo.url_map (long_url, expiry_date) Values ('" + tbLongURL.Text + "', '" + DateTime.Today + "')";

Answer 2

If you use parameters I think your query should be
query = "INSERT INTO dbo.url_map (long_url, expiry_date) Values (#long_url, #expiry_date)";
//this way sqlcommand make sense
SqlCommand cmd = new SqlCommand(query, con);
cmd.Parameters.AddWithValue("#long_url", tbLongURL.Text);
cmd.Parameters.AddWithValue("#expiry_date", DateTime.Today);

protected void Button1_Click(object sender, EventArgs e)
{
Insert();
}
public void Insert()
{
try
{
_conn = new SqlConnection(con);
_cmd = new SqlCommand();
_cmd.Connection = _conn;
_conn.Open();
_cmd.CommandType = CommandType.StoredProcedure;
_cmd.CommandText = "insert_date";
_cmd.Parameters.Add("#Date",SqlDbType.DateTime).Value = DateTime.Now;
_cmd.ExecuteNonQuery();
_conn.Close();
}
catch (Exception ex)
{
}
}
Stored Procedure:
create procedure insert_date
#Date datetime
as
insert into DateTable values(#Date)
Result after insertion on table:
1 2013-06-26 14:29:36.987

Answer 4

You can directly bind the Current Date to 'expiry_date' column in SQL server.
Steps:
Right click on your table and select 'Design'.
Click on the desired column, 'expiry_date' in your case.
In the column property, look for 'Default Value or Binding' in General Section.
Put 'GETDATE()' as the default value, so whenever you insert the record, it will take current date as its value.
