4 years ago Hello @kenzouno1 ,
Could you provide a runnable code/project with this issue.
My developer tried it but didn't get a similar error;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.EntityFrameworkCore;
namespace lab.EFCore20.PostgreSQL
{
class Request_Update_IDDouble
{
public static void Execute()
{
bool createAndDeleteBD = true;
if (createAndDeleteBD)
{
// Create BD
using (var context = new EntityContext())
{
My.DeleteBD(context);
context.Database.EnsureCreated();
}
}
// CLEAN
using (var context = new EntityContext())
{
context.EntitySimples.RemoveRange(context.EntitySimples);
context.SaveChanges();
}
// SEED
using (var context = new EntityContext())
{
context.EntitySimples.Add(new EntitySimple { ColumnInt = 1 });
context.EntitySimples.Add(new EntitySimple { ColumnInt = 2 });
context.EntitySimples.Add(new EntitySimple { ColumnInt = 3 });
context.SaveChanges();
}
// TEST
using (var context = new EntityContext())
{
List<EntitySimple> list = new List<EntitySimple>();
list.Add(new EntitySimple { ColumnInt = 10 });
list.Add(new EntitySimple { ColumnInt = 11 });
list.Add(new EntitySimple { ColumnInt = 12 });
context.BulkInsert(list);
var listId = list.Select(x => x.ID).ToList();
// context.EntitySimples.Where(x => listId.Contains(x.ID)).Update(x => new EntitySimple() {ColumnString = "TEST"});
context.EntitySimples.Where(x => listId.Contains(x.ID)).UpdateFromQuery(x => new EntitySimple() {ColumnString = "TEST"});
var testaa = context.EntitySimples.ToList();
}
}
public class EntityContext : DbContext
{
public EntityContext()
{
}
public DbSet<EntitySimple> EntitySimples { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseNpgsql(My.Connection);
}
}
public class EntitySimple
{
public int ID { get; set; }
public int ColumnInt { get; set; }
public String ColumnString { get; set; }
}
}
}

4 years ago Exactly this not working if Model has Property type ComplexType. How to remove ComplexType Field on the query?
That is my code.

4 years ago Hello @kenzouno1 ,
Just to give you an update, we successfully reproduced the issue even on SQL Server by using your code.
My developer will try something this week by explicitly selecting column or by modifying the SQL to make sure column alias are unique.
I will keep you updated

4 years ago Hello @kenzouno1 ,
It took us more time than expected but my developer successfully fixed the issue.
However, we only succeed to make the fix for EF Core 3.x ;(
I believe you currently use EF Core 2.x and for this version, we never found how to do it correctly since column alias are missing unlike EF Core 3.x

4 years ago I think need a feature blacklist properties. Can you do that?

commented
4 years ago It depends,
Let us know more about your idea ;)

4 years ago I'm not real .Net developer so I don't know how to do it.
But i think on query you need get all Properties of Model. So why not have a feature add a Black List Property Names and on query will remove it from List Properties before execute command
