References Required:
- using Domain; //this is the folder where your entities are found
- using NHibernate;
- using NHibernate.Criterion;
Other Requirements:
- Nhibernate / Fluent Nhibernate
- Linq for Nhibernate
- Nhibernate Session Helper (can find ready ones on the internet)
1. Return a row by integer Id
public Movies GetById(intId)
{
using(ISession session = NHibernateHelper.OpenSession())
return session.Get<Icon>(Id);
}
2. Return a simple IList<> / Return all rows in a table:
public IList<Movies> GetAll()
{
using(ISession session = NHibernateHelper.OpenSession())
return session.CreateCriteria(typeof(Movies)).List<Movies>();
}
3. Return an IList<> with a WHERE clause:
public IList<Movies> GetMoviesByCategory(int CatId)
{
using(ISession session = NHibernateHelper.OpenSession())
return session.CreateCriteria(typeof(Movies)).Add(Restrictions.Eq(“CategoryId”, CatId)).List<Movies>();
}
4. Return an IList<> with a 3-way JOIN and WHERE clause
public IList<MovieImages> GetMovieImagesByMovieCategory(int CatId)
{
IList<Movie> movies = GetAllMovies(); //Change with your query
IList<MovieCategory> categories = GetAllCategories(); //Change with your query
IList<MovieImages> images = GetAllImages(); //Change with your query
using(ISession session = NHibernateHelper.OpenSession())
| return |
|
(from mi in images |
|
|
join m in movies on mi.Movie.Id equals m.Id |
|
|
join c in categories on m.CategoryId.Id equals c.Id |
|
|
where c.Id == category.Id |
|
|
select mi).ToList<MovieImages>(); |
}
5.Convert List to IList<>
IList<MovieImages> list = myNormalList.ToList<MovieImages>(); //myNormalList would be a common List()
