如何将对象传递给oracle存储过程(odp) [英] how to pass an object to oracle stored procedure(odp)

问题描述

我需要将一个对象传递给存储过程以插入数据..
我尝试过此编码

I need to pass an object to stored procedure for inserting the data..
I tried this coding

button_click()
{
 insert_pro insobj = new insert_pro();
            insobj.ID = Convert.ToInt16(textBox1.Text);
            insobj.Name = textBox2.Text;
            insobj.Gender =Convert.ToChar(textBox3.Text);


            OracleConnection conn = new OracleConnection("Data Source=r2a;User ID=testv55;Password=testv55;");
            conn.Open();
            OracleCommand cmd = new OracleCommand("smp_ins", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            OracleParameter emp_obj = new OracleParameter();
            emp_obj.OracleDbType = OracleDbType.Object;
            emp_obj.Direction = ParameterDirection.Input;
            emp_obj.UdtTypeName = "EMP_TYP";
            emp_obj.Value = insobj;
            cmd.Parameters.Add(emp_obj);

            cmd.ExecuteNonQuery();
            con.close();
}

insert_pro类别:

insert_pro class:

namespace test_form
{

 public  class insert_pro:IOracleCustomType
    {
        [OracleObjectMappingAttribute("Id")]
        public virtual int  ID { get; set; }

        [OracleObjectMappingAttribute("Name")]
        public virtual string Name { get; set; }

        [OracleObjectMappingAttribute("Gender")]
        public virtual char Gender { get; set; }


        public virtual void FromCustomObject(OracleConnection conn, IntPtr objUdt)
        {

            OracleUdt.SetValue(conn, objUdt, "Id", this.ID);
            OracleUdt.SetValue(conn, objUdt, "Name", this.Name);
            OracleUdt.SetValue(conn, objUdt, "Gender", this.Gender);

        }
        public virtual void ToCustomObject(OracleConnection conn, IntPtr objUdt)
        {
            this.ID = ((int)(OracleUdt.GetValue(conn, objUdt, "Id")));

            this.Name = ((string)(OracleUdt.GetValue(conn, objUdt, "Name")));

            this.Gender = ((char)(OracleUdt.GetValue(conn, objUdt, "Gender")));

        }
    }
}

错误消息是未指定"test_form.insert_pro"的自定义类型映射或无效

error message is Custom type mapping for ''test_form.insert_pro'' is not specified or is invalid

推荐答案

忘记创建IOracleCustomTypeFactory

forget to create IOracleCustomTypeFactory

[OracleCustomTypeMappingAttribute("TESTV55.SMP_EMP_TYPE")]
 
 public class ins_Factory : IOracleCustomTypeFactory
 {
    
     public virtual IOracleCustomType CreateObject()
     {
         insert_pro obj = new insert_pro();
           return obj;
     }
 
    
}
