Can't insert date in firebird using datetimepicker c#

Question

I would like to ask for your help about my datetimepicker . I can't insert date to my firebird database, my firebird version is 2.5.4 . my DATE in firebird has datatype of DATE ; I've also tried TIMESTAMP .

This is my code:

private void button1_Click(object sender, EventArgs e)
{
    FbConnection con = new FbConnection(BackEndCode.clKoneksyon.DbCon());
    FbCommand cmd = new FbCommand("INSERT INTO TBLLAN_SETUP (DATE) VALUES (@DATE)", con);
    cmd.Parameters.AddWithValue("@DATE", dtpDate.Value.Date.ToShortDateString());

    con.Open();
    cmd.ExecuteNonQuery();
    con.Dispose();
    con.Close();
    cmd.Dispose();
}

i also try this with no luck

cmd.Parameters.AddWithValue("@DATE", dtpDate.Value.Date);

This is the error I got

An unhandled exception of type 'FirebirdSql.Data.FirebirdClient.FbException' occurred in FirebirdSql.Data.FirebirdClient.dll

EDIT: Updated code with exception handling

private void button1_Click(object sender, EventArgs e)
{

    FbConnection con = new FbConnection(BackEndCode.clKoneksyon.DbCon());
    FbCommand cmd = new FbCommand("INSERT INTO TBLLAN_SETUP (DATE) VALUES (@DATE)", con);
    cmd.Parameters.AddWithValue("@DATE", dtpDate.Value.Date);
    try
    {
        con.Open();
        cmd.ExecuteNonQuery();
    }

    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    finally
    {
        con.Dispose();
        con.Close();
        cmd.Dispose();
    }
}

Answer 1

DATE是保留字，因此请尝试：

"INSERT INTO TBLLAN_SETUP ([DATE]) VALUES (@DATE)"
