UdtTypeName

This attribute sets the OracleParameter.UdtTypeName property value via a class property. Required whenever the parameter binds an Oracle user-defined type (object type or collection).

Attribute

Example usage:

public class Person
{
    public int Id { get; set; }

    [UdtTypeName("SCHEMA.MY_TYPE")]
    public object Metadata { get; set; }
}

Fluent Mapping

To configure via FluentMapper:

FluentMapper
    .Entity<Person>()
    .PropertyValueAttributes(e => e.Metadata, new UdtTypeNameAttribute("SCHEMA.MY_TYPE"));

Retrieval

Retrieve the attribute via PropertyValueAttributeCache:

var attribute = PropertyValueAttributeCache
    .Get<Person>(e => e.Metadata)?
    .FirstOrDefault(e => e.GetType() == typeof(UdtTypeNameAttribute));

We strongly recommend using PropertyValueAttributeCache for maximum performance.
