Datetimepicker 值不能存储在 Access 数据库中

Question

我是 MS-Access 和 C# 的新手，我在从 DateTimePicker 向数据库中插入新记录时遇到问题，因为 c# 程序出现以下错误：

Insert into statement is not correct.

所以我想知道：我该如何解决这个问题？

private void btn_insert_Click(object sender, EventArgs e)
{
    try
    {
        connection.Open();
        OleDbCommand command = new OleDbCommand();
        command.Connection = connection;
        command.CommandText = "insert into BP (Name,DateTime,Systolic,Diastolic) VALUES('" + txt_Name.Text + "', '" + dateTimePicker1.Text + "' ," + txt_systolic.Text + "," + txt_diastolic.Text + ");";
        command.ExecuteNonQuery();
        MessageBox.Show("Changes made Succesfully");
        connection.Close();
    }
    catch (Exception ex)
    {
        MessageBox.Show("ERROR " + ex);
    }
    connection.Close();
}

Answer 1

您必须为日期值传递格式正确的字符串表达式并使用正确的 Access SQL 语法，并且名称是保留字，因此：

command.CommandText = "insert into BP ([Name],DateTime,Systolic,Diastolic) VALUES('" + txt_Name.Text + "', #" + dateTimePicker1.Value.ToString("yyyy'/'MM'/'dd hh':'mm':'ss") + "# ," + txt_systolic.Text + "," + txt_diastolic.Text + ");";
