Insert, select and update DateTime

Question

I have a table with time the column named time and the datatype is Date.

In asp.net I want a query to insert the date, and another so select between 2 date.

Answer 1

If the table really is a DATE/DATETIME/DATETIME2/SMALLDATETIME, you'd be better off doing something more like:

using (SqlCommand cmd = new SqlCommand("INSERT INTO example (date) values (@param)"))
{
    cmd.Paramters.Add("@param", SqlDbType.Datetime).Value = DateTime.Now;

    cmd.ExecuteNonQuery();
}

Similarly, when you query the table, something more like:

using (SqlCommand cmd = new SqlCommand("SELECT * FROM example WHERE date BETWEEN @FromDate AND @ToDate"))
{
    cmd.Paramters.Add("@FromDate", SqlDbType.Datetime).Value = DateTime.Now;
    cmd.Paramters.Add("@ToDate", SqlDbType.Datetime).Value = DateTime.Now; // Of course, you'd probably want to pass through values as parameters to your method

    // Fill your dataset/get your SqlDataReader, etc. as preferred
}
