db4o native query in C#: how to find by first number?
0
- I want to change last number of my every "No" for all students (who is born between 1996 and 1998) to 0, for example. (from 160456 to 1604560)
- I want to delete data for students whos "No" first 2 numbers is 14, for example. (user2.No = 143457;)
How to find data only by 1 or more numbers?
I'm using Linq:
using System.Linq;
using Db4objects.Db4o.Linq;
My database look like this:
User user1 = new User();
user1.Name = "Bob";
user1.Surname = "Topson";
user1.No = 160456;
user1.Birth = new DateTime (1998, 5, 12);
User user2 = new User();
user2.Name = "Rob";
user2.Surname = "Simpson";
user2.No = 143457;
user2.Birth = new DateTime (1996, 8, 4);
my user.cs code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace db4o
{
class User
{
public string Name { get; set; }
public string Surname { get; set; }
public int No { get; set; }
public DateTime Birth { get; set; }
}
}
.net linq db4o
