Question

当我使用这个

时

con.Open();
OleDbCommand conup = new OleDbCommand(@"UPDATE  [user1],
SET   name = '" + textBox1.Text + "' , password ='" + textBox2.Text + "', <br>remember ='" + remember + "' WHERE (name='" + textBox1.Text + "')", con);
conup.ExecuteNonQuery();
con.Close();

它显示了一个异常

密码是Access中的保留字，更新名称是没有意义的，因此：

OleDbCommand conup = new OleDbCommand(@"UPDATE [user1] SET [password] = '" + textBox2.Text + "', remember = '" + remember + "' WHERE ([name] = '" + textBox1.Text + "')", con);

我正在尝试更新Access中的数据
