Question

Hi I have an object called document and one called user

Document

    public virtual string Name { get; set; }
    public virtual string Description { get; set; }
    public virtual User User { get; set; }

Documentmap

    public DocumentMap()
    {
        Map(x => x.Name);
        Map(x => x.Description);
        References(x => x.User);
    }

User

    public virtual string UserId { get; set; }
    public virtual string FirstName { get; set; }
    public virtual string MiddleInitial { get; set; }
    public virtual string LastName { get; set; }
    private readonly IList<Document> _documents = new List<Document>();
    public virtual IEnumerable<Document> Documents { get { return _documents; } }
    public virtual void Remove(Document document)
    {
        _documents.Remove(document);
    }
    public virtual void Add(Document document)
    {
        if (!document.IsNew() && _documents.Contains(document)) return;
        _documents.Add(document);
    }

    Map(x => x.UserId);
        Map(x => x.FirstName);
        Map(x => x.MiddleInitial);
        Map(x => x.LastName);
        HasMany(x => x.Documents).Access.CamelCaseField(Prefix.Underscore); 

Pretty straighforward ( they inherit from base class with stuff like createddate modifieddate etc )

when I try to get all doc by userid I get this

Invalid column name ‘UserId’.

the column most definitely is in the table. It also lists several of the base class items as not being there.

I take the sql and past it in query manager and I get intellisense saying they are invalid columns. I run it and it executes just fine. Further more there are plenty of other objects using these base classes with no problems.

I have tried various things like explicitly mapping the key name, the column name using inverse etc to no avail. Don’t really know what to do.
Thanks,
Raif

//EDIT as per request sorry it’s so verbose. the database is created by nhibernate create schema

Document

public class Document : Entity
{
    public virtual string Name { get; set; }
    public virtual string Description { get; set; }
    public virtual DocumentCategory DocumentCategory { get; set; }
    [ValueOf(typeof(DocumentFileType))]
    public virtual string FileType { get; set; }
    public virtual string FileUrl { get; set; }
    public virtual int? Pages { get; set; }
    public virtual decimal? Size { get; set; }
    public virtual User User { get; set; }
}

public class DocumentMap : EntityMap<Document>
{
    public DocumentMap()
    {
        Map(x => x.Name);
        Map(x => x.Description);
        Map(x => x.FileUrl);
        Map(x => x.Pages);
        Map(x => x.Size);
        Map(x => x.FileType);
        References(x => x.DocumentCategory);
        References(x => x.User);
    }
}

Entity

public class Entity : IGridEnabledClass, IEquatable<Entity>
{
    public virtual int EntityId { get; set; }
    public virtual DateTime? CreateDate { get; set; }
    public virtual DateTime? ChangeDate { get; set; }
    public virtual int ChangedBy { get; set; }
    public virtual bool Archived { get; set; }

    public virtual bool IsNew()
    {
        return EntityId == 0;
    }

User

 public class User : DomainEntity, IUser
{
    public virtual string UserId { get; set; }
    [ValidateNonEmpty]
    public virtual string FirstName { get; set; }
    public virtual string MiddleInitial { get; set; }
    [ValidateNonEmpty]
    public virtual string LastName { get; set; }
    public virtual string Title { get; set; }
    public virtual DateTime? BirthDate { get; set; }
    public virtual string StartPage { get; set; }
    public virtual UserLoginInfo UserLoginInfo { get; set; }
    public virtual UserStatus UserStatus { get; set; }
    public virtual Photo HeadShot { get; set; }
    private readonly IList<Document> _documents = new List<Document>();
    public virtual IEnumerable<Document> Documents { get { return _documents; } }
    public virtual void Remove(Document document)
    {
        _documents.Remove(document);
    }
    public virtual void Add(Document document)
    {
        if (!document.IsNew() && _documents.Contains(document)) return;
        _documents.Add(document);
    }
    several more collections

public class UserMap : DomainEntityMap<User>
{
    public UserMap()
    {
        Map(x => x.UserId);
        Map(x => x.FirstName);
        Map(x => x.MiddleInitial);
        Map(x => x.LastName);
        Map(x => x.BirthDate);
        Map(x => x.StartPage);
        References(x => x.UserStatus);
        References(x => x.UserLoginInfo);
        References(x => x.HeadShot);
        HasMany(x => x.Documents).Access.CamelCaseField(Prefix.Underscore); 

database tables create from script select to menu item on management studio

  SELECT [EntityId]
  ,[CreateDate]
  ,[ChangeDate]
  ,[ChangedBy]
  ,[Archived]
  ,[Name]
  ,[Description]

Answer 1

Make sure nhibernate is querying against the same database as what you are querying against in sql management studio.
