Question

I need to store the date fetch from the ASP.Net text box into a SQL Server 2008 date column.

I am getting the following exception message.

Conversion failed when converting date and/or time from character string.

My code is:

SqlConnection cn;
SqlCommand cmd;
SqlDataAdapter da;

int n=4;
protected void Page_Load(object sender, EventArgs e)
{
    cn = new SqlConnection(<Connection String>);
}

protected void Button1_Click(object sender, EventArgs e)
 {
        try
      {
          string query = "insert into temp values('" + TextBox1.Text  + "')";
          cn.Open();
          cmd = new SqlCommand(query, cn);
          cmd.ExecuteNonQuery();
          cn.Close();
          Response.Write("Record inserted successfully");
     }
    catch (Exception ex)
    {
         Response.Write(ex.Message);
    }

}

Please help ..

Thanks in advance

Answer 1

you have to do multiple changes

1. Convert your date as DateTime
2. Pass value as parameter to avoid SQL injection
3. Set the field as DateTime in DB.

Your code would be like that

SqlConnection cn;
SqlCommand cmd;
SqlDataAdapter da;

int n=4;
protected void Page_Load(object sender, EventArgs e)
{
cn = new SqlConnection(<Connection String>);
}

protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
      string query = "insert into temp values(@date))";
      cn.Open();
      cmd = new SqlCommand(query, cn);
      cmd.Parameters.AddWithValue("@date",Convert.DateTime(TextBox1.Text));
      cmd.ExecuteNonQuery();
      cn.Close();
      Response.Write("Record inserted successfully");
    }
    catch (Exception ex)
    {
     Response.Write(ex.Message);
    }

}
