Convert These 4 SQL Tables Into OO Classes (Java Or C#) But Not With NHibernate/LINQ?

Apr 21, 2012

I am trying to learn OOD/OOP and read on the net that I am not supposed convert SQL tables into classes. But I cannot find an explanation why not to do it or which tables to skip. So I made an web application based on the below diagram. It works perfectly well. But I do not use OO. which table should not be mapped into a class and why not. do not use LINQ or NHibernate, etc as I do not understand them. I just need to understand the OOD.

MS Entity Framework VS NHibernate And Its Derived Contribs (FluentNHibernate, Linq For NHibernate)?

Feb 4, 2010

I just read this article about the Entity Framework 4 (actually version 2).Entity Framework seems to offer a huge improvement over its first release. Thus, I have never ever used EF in any project, since I think EF is not mature enough in comparison to NHibernate.NHibernate and its current contributions of FluentNHibernate and Linq for NHibernate by Ayende RahienMy feeling is that Microsoft is solely trying to gain terrain it has lost in favor of NHibernate when the 2nd version of NHibernate came out.Nevertheless, my concerns are the followings (not in particular order):Will EF4 tend to be less XML-verbose?Will EF4 be compatible with other underlying datastore than just SQL Server?What are the greatest benefits of going with EF4 instead of FluentNHibernate or NHibernate itself.

NHibernate is a great tool, I guess everyone agrees. Due to its predecessor Hibernate, we may easily find documentions and tutorials and sample applications to get acquainted with it. This is not the case for FluentNHibernate. Particularly as per the project I'm working on right now which demands that I investigate further about NHibernate and its options (FluentNHibernate for instance) in order to document the rules of usage and the best practices of NHibernat and FluentNHibernate technology. Thus, being handcuffed with VB.NET, being a C-Style developer, I can't find some syntax equivalencies in VB.NET for the examples provided, though I made I way so far

.net :: Convert C# Classes (class Library) To SQL DDL (tables)?

Aug 4, 2010

I have to convert a set of C# classes (class library) to SQL tables to be used by SQL Server, so that the data can be stored in a database and manipulated through the database.The problem is that the number of these classes is big (more than 1000 classes),and it would take a long time to setup manually such a database schema (tables,ndexes, stored procedures, etc.) - not to mention the class hierarchies that I need to maintain.

Handle Property Mappings To Other Domain Classes That Aren't Yet Mapped With NHibernate?

Sep 8, 2010

I'm working on a project to replace ADO.NET data access logic using NHibernate where we're not able to map the entire domain model at once. This means we'll have domain classes with property mappings to other domain classes that aren't yet mapped with NHibernate.

Consider a Person class with an Address property (Address being a domain object without an NH mapping and Person being the class I'm mapping). How can I include Address in the Person mapping without creating an entire mapping for Address? Is it possible to call legacy (ADO.NET) data access logic from a custom PropertyAccessor? If so, is it reasonable?

*I asked this within another question here but didn't get a response. I'm hoping to get one in a more concise question.

.net - Can't Get Linq To NHibernate To Work?

Nov 22, 2009

I'm struggling with getting Linq To NHibernate to work.I have referenced NHibernate, NHibernate.Linq and NHibernate.ByteCode.Castle . Also I have all other dependencies in the same folder.

Code / Error message:

Public Function GetProjectsByName(ByVal ProjectName As String) As List(Of Project)
Return (From x In _session.Linq(Of Project)() Where x.Name.Equals(Project))

End Function[code]....

... tells me that the LINQ extensions aren't loaded. Using NHibernate.Linq seems to be made in a way that it's incredibly easy to use, hence there are no tutorials on how to set it up. (Or at least I couldn't find any).

VS 2008 .NET For NHibernate And Fluent NHibernate?

Oct 26, 2010

I would like to ask if you can use VB.NET for NHibernate and Fluent Nhibernate?I have searched the web, but I can't seem to get a detailed or explicit statement that tells that one can use VB.NET for NHibernate and with Fluent.

Many of the samples in the NHibernate site are made in C#. That's why I was wondering if I can't use VB.NET when using NHibernate.

Convert Java Class To Vb 2008 Application?

Oct 29, 2009

I wrote a Java class that parses a bpel text file and then returns a count of the number of occurences of certain words. I wanted to convert it to VB2008 Forms application, so that its results are displayed in a TextBox and not on the console. The problem is that VB2008 lacks Scanner and StringTokenizer classes, which are in my current Java class. Am not sure how to get the same functionality (or better) in VB2008. Can someone out there help to convert this class.

LINQ To SQL Classes Not CLS-Compliant?

Aug 5, 2009

I'm using LINQ to SQL as my data access layer for a new project.I have added my database tables to the designer and all is well.Whenever I use one of these classes in a function, Visual Studio warns me that 'Type xxxx is not CLS-compliant' or that 'Return type of function xxxx is not CLS-compliant' Is this a problem with the classes that LINQ to SQL generates? Does it matters? Can I disable these warnings anywhere? My VS error list is clogged up with these warnings making it hard to see anything else.

VB 2008 LINQ To SQL Classes - How To Use App Role

I am curious as to the proper technique to use SQL Server's AppRole with a LINQ to SQL Class. I understand I have to establish the intial connection with no connection pooling. However, do I simply call the SQL stored procedure sp_setapprole using standard LINQ before executing any of my methods that interact with the database, or is there a better way to enable and use AppRole within the LINQ to SQL class?

However, all of my LINQ statements are hard-coded. Are there available solutions / modules which will provide me with a LINQ command and RESULTS window which can be set to an instance of a class so I can experiment with other commands runtime? Can LinqPad be used runtime against populated classes?

LINQ To SQL And Join Two Tables With OR Clause

Apr 23, 2009

Let's say I have Plans and Documents
Dim myPlans = _context.Plans.Where(predicate1)
Dim myDocuments = _context.Documents.Where(predicate2)

I have structured the where clause for each using PredicateBuilder. So, myPlans and myDocuments have a correct SQL statement. What I'd like to do is join these two tables into one linq statement. The problem I'm having is that, by default the AND condition is joining the where clauses.

myPlans Where clause : (p.name like "%test%" AND p.name like "%bed%") OR (p.description like "%test%" AND p.description like "%bed%")
myDocuments Where clause : (d.name like "%test%" AND d.name like "%bed%") OR (d.description like "%test%" AND d.description like "%bed%")

When I combine the two the desired result Where clause is:
Where (d.ID = p.ID) AND
(myplans where clause above) OR (mydocument where clause above). Meaning, I'd like the two where clauses in each of the tables to be "or" instead of "And".

The current result where clause is:
Where (d.ID = p.ID) AND
(myplans where clause above) AND (mydocument where clause above). Meaning, I'd like the two where clauses in each of the tables to be "or" instead of "And".

I'm forming the statement like this:
Dim test = From d in myDocuments _
Join p in MyPlans on d.ID Equals p.ID _
Select d.Name, p.Name

Aggregating Parent/child Tables Using Linq To SQL?

Sep 18, 2009

I'm having a nightmare with LINQ. I've got a table of Projects, and each project has many InvoiceHeaders. The Invoice header had a field AmountNet - the value of the invoice.

I want to retrive, for arguments sake, all of the fields from Projects, with the count of invoice headers and the sum of AmountNet. I.e. list of my projects, how many invoices I've raised and the value.

Doesn't sound hard does it.... well, I've just spent the best part of two hours charging through Google and SO to find a solution.

Asp.net - Return Two Tables From A Stored Procedure From LINQ To SQL?

Aug 4, 2011

I have written a stored procedure like this:

CREATE PROCEDURE [dbo].[TestProcedure]
AS
BEGIN
SELECT TOP 1 CampaignID FROM Campaigns
SELECT TOP 1 ServiceID FROM Services ORDER BY ServiceID desc
END

In my .NET Project, I have a LINQ to SQL file (.dbml) and I have drag-and-dropped this procedure to create a new class TestProcedureResult:

Partial Public Class TestProcedureResult
Private _CampaignID As Integer
Public Sub New()

[Code]....

So it is not returning ServiceID. How can I retreive ServiceID using LINQ to SQL? I know we can customize stored procedure calls, but how can I customize in this particular scenario?
