fluent

I'm trying to create mysql UPDATE query that will take parameters. In addition I want to append to the end of the field if the field isnt empty. For that I'm using CASE statement. Here's my query in doctrine (from silex): $query = "UPDATE table SET filed = ( CASE WHEN field = '' THEN :param1 ELSE concat(field, :param1) END) WHERE id=:param2"; $app['db']['test_db']->executeUpdate($sql, array('param1' => $user_text, 'param2' => $selected_id)); Now I want to convert it to fluent or raw query so I can use it in Laravel 4. Here's my code: $param1 = "String..."; // user string $param2 = 45; // id DB

i have these 2 classes: public class Category { IDictionary<string, CategoryResorce> _resources; } public class CategoryResource { public virtual string Name { get; set; } public virtual string Description { get; set; } } and this is xml mapping <class name="Category" table="Categories"> <id name="ID"> <generator class="identity"/> </id> <map name="Resources" table="CategoriesResources" lazy="false"> <key column="EntityID" /> <index column="LangCode" type="string"/> <composite-element class="Aca3.Models.Resources.CategoryResource"> <property name="Name" column="Name" /> <property name=

I just started with NHibernate, created my mappings using fluent NHibernate as follows: public class CustomerMap : ClassMap<Customer> { public CustomerMap() { Id(x => x._id, "Id"); Map(x => x._KdNr, "KdNr"); Map(x => x._Name, "Name"); HasMany(x => x._Contact) .Table("Contacts") .KeyColumn("FKCustomerID") .LazyLoad(); } } public class ContactMap : ClassMap<Contact> { public ContactMap() { Id(x => x._id, "Id"); Map(x => x._Name, "Name"); } } And to save new records works also: public static void AddCustomer(Customer cust) { using (var session = SessionFactory.Instance.OpenSession()) { session

使用数据注解 实体类通常是在 Models 目录下,直接在实体类上添加属性注解，比如 [Required]/[Key] 等. using System.ComponentModel.DataAnnotations; public class User() { [Key] public string UserId { get; set; } [Required] public string UserName { get; set; } } 重写配置方法 在自己实现的 XxxDbContext 数据库上下文类中重写配置方法，用 Fluent API 的方式添加所有实体的配置. using Microsoft.EntityFrameworkCore; public partial class XxxDbContext : DbContext { public XxxDbContext() { } public HaoyikuDbContext(DbContextOptions<HaoyikuDbContext> options) : base(options) { } public DbSet<User> Users { get; set; } // 重写以下方法 protected override void OnModelCreating(ModelBuilder

I am sure it is a piece of cake, but I can't find it using google. I need to EXCLUDE a single class from mapping. My current configuration is: return Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(c => c.Is(@"Data Source=PC\SQLEXPRESS;......"))) .Mappings(m => m.AutoMappings.Add( AutoPersistenceModel.MapEntitiesFromAssemblyOf<Person2>() .Where(t => t.Namespace == "ExampleData.HumansTest") .UseOverridesFromAssemblyOf<PersonMappingOverrides>() .ConventionDiscovery.AddFromAssemblyOf<PersonMappingOverrides>() ) ).BuildConfiguration(); Works nice, so far... But I have

I am trying to map a composite key for an entity. public class Customer { public int CustomerId { get; set; } public virtual List<CustomerImage> CustomerImages { get; set; } } And its Map: public class CustomerMap : EntityTypeConfiguration<Customer> { public CustomerMap() { HasKey(t => t.CustomerId); ToTable(DbConstants.k_CustomersImageTable); } } An Image: public class Image { public int ImageId { get; set; } } And its map: public class ImageMap : EntityTypeConfiguration<Image> { public ImageMap() { HasKey(t => t.ImageId); ToTable(DbConstants.k_ImagesTable); } } And the navigation property:

If using Fluent NHibernate, is it possible to automap most classes, but specify that a couple of particular classes should be mapped using the regular fluent API rather than being automapped? And if so, can anyone point me to some sample code that shows how to do it? Thanks! It is possible and easy to mix-up mapping configurations: var cfg = Fluently.Configure() .Database(configurer) .Mappings(map => { // Automapping map.AutoMappings.Add(AutoMap.Assemblies(Assembly.GetExecutingAssembly()) .Where(type => type == typeof(Domain.Market.Share)) .Where(type => type == typeof(Domain.HR.Employee))); /

I'm trying to map a view without an identifier, but nhibernate still generates a sql with the id column (giving me a sql error, since the ID column does not exists in the db). Maybe I'm misunderstanding the Id() constructor? constructor comments: Create an Id that doesn't have a corresponding property in the domain object, or a column in the database. This is mainly for use with read-only access and/or views. Defaults to an int identity with an "increment" generator. public class PersonMapping : ClassMap<Person> { public PersonMapping() { Table("person"); ReadOnly(); Id(); Map(f => f.Name,

I need to set up a relationship that is currently a one-to-many: public class Foo { public int FooId { get; set; } public int? BarId { get; set; } ... public virtual Bar Bar { get; set; } } public class Bar { public int BarId { get; set; } ... public virtual ICollection<Foo> Foos { get; set; } } public FooMap() { HasKey(e => e.FooId); Property(e => e.FooId.IsRequired().HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity); Property(e => e.BarId).IsOptional(); ... HasOptional(e => e.Bar).WithMany(Foos).HasForeignKey(e => e.BarId); } public BarMap() { HasKey(e => e.BarId); Property(e => e
