我在CodeFirst中使用EF4。
public class MyContext : DbContext
{
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Conventions.Remove<XXX>();
modelBuilder.Conventions.Add<XXX>());
}
}
我应该添加或删除哪些约定来使所有数据库标识符(如列名,表名,存储过程等)都是大写(或不带引号)?
Oracle DB中的案例发送(引用)标识符非常糟糕,用户友好。

考虑产品和客户类
public class Product {
public int Id { get; set; }
public string Name { get; set; }
public int Stock { get; set; }
}
public class Customer {
public int Id { get; set; }
public string Name { get; set; }
}
public class MyDbContext : DbContext {
public DbSet<Product> Product { get; set; }
public DbSet<Customer> Customer { get; set; }
public MyDbContext() { }
protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) {
modelBuilder.Conventions.Remove<PluralizingEntitySetNameConvention>();
modelBuilder.Conventions.Add<TableNameUppercaseConvention>();
base.OnModelCreating(modelBuilder);
}
}
public class TableNameUppercaseConvention : IConfigurationConvention<Type, EntityTypeConfiguration> {
public void Apply(Type typeInfo, Func<EntityTypeConfiguration> configuration) {
configuration().ToTable(typeInfo.Name.ToUpper());
}
}
我试图做这样的事情,但似乎不起作用,为什么
public class ColumnUppercaseConvention : IConfigurationConvention<MemberInfo, PrimitivePropertyConfiguration> {
public void Apply(MemberInfo memberInfo, Func<PrimitivePropertyConfiguration> configuration) {
configuration().ColumnName = memberInfo.Name.ToUpper();
}
}
我最好的方法是
public class Customer {
[Column(Name = "ID")]
public int Id { get; set; }
[Column(Name = "NAME")]
public string Name { get; set; }
}
抱歉,我现在无法帮助,但我会继续努力。

我不知道如何使用约定来执行此操作,但请查看StoreNameAttribute。您可以应用上下文,实体和属性。
