ADO.NET/C# ile Dizilim/Tablo Parametresini Oracle'a (ODP.NET 10g) nasıl kullanılır?

Question

This answer için this question iyi, ancak bir Oracle yordamına bir dizi veya tablo göndermek ve sonra bu tabloyu yordamda kullanmak için ADO.NET kodunu arıyorum. SQL Server tablo değerli parametreler

, oldukça basittir:

CREATE TYPE [dbo].[IntTable] AS TABLE(
    [intvalue] [int] NOT NULL, 
    PRIMARY KEY CLUSTERED 
    (
     [intvalue] ASC 
    )WITH (IGNORE_DUP_KEY = OFF) 
) 
GO 

CREATE PROCEDURE dbo.UseTable 
    @SomeInt INT 
    ,@IntTable dbo.IntTable READONLY 
AS 
BEGIN 
    -- Do whatever using @SomeInt and @IntTable like: 
    INSERT INTO Assignments (masterid, childid) 
    SELECT @SomeInt, intvalue 
    FROM @IntTable 
END 
GO 

Sonra istemci üzerinde:

CREATE OR REPLACE TYPE TRAIT_ID_TABLE AS TABLE OF NUMBER; 

PROCEDURE SET_TRAITS(P_CUST_TANK_PROD_ID IN CUST_TANK_PROD.CUST_TANK_PROD_ID%TYPE, P_TRAIT_IDS IN TRAIT_ID_TABLE) 
AS 
BEGIN 
    DELETE FROM TANK_TRAIT 
     WHERE CUST_TANK_PROD_ID = P_CUST_TANK_PROD_ID; 

    INSERT INTO TANK_TRAIT(CUST_TANK_PROD_ID, TRAIT_ID) 
    SELECT P_CUST_TANK_PROD_ID, COLUMN_VALUE FROM TABLE(P_TRAIT_IDS); 

    COMMIT; 
EXCEPTION 
    WHEN OTHERS 
    THEN 
    ROLLBACK; 
END; 


var param = new OracleParameter(); 
param.ParameterName = "P_TRAIT_IDS"; 
param.OracleDbType = OracleDbType.Decimal; 
param.CollectionType = OracleCollectionType.PLSQLAssociativeArray; 
param.Direction = ParameterDirection.Input; 
param.Value = traitIdList.ToArray<int>(); 
param.Size = traitIdList.Count; 
cmd.Parameters.Add(param); 

Ve:

var param = new List<int>(); 
param.Add(1); 
param.Add(2); 

Cm.Parameters 
    .AddWithValue("@IntTable", param /* IEnumerable<Int> */) 
    .SqlDbType = SqlDbType.Structured 

Bu şu anda ne var Bunu ExecuteNonQuery'de alıyorum:

System.AccessViolationException was caught 
    Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Bu ODP.NET için çalışır (odac):

Oracle paketi olacak kurulum gibi:

string connStr = "User Id=xxx;Password=xxxx;Data Source=xxxxx;"; 
OracleConnection _conn = new OracleConnection(connStr); 
_conn.Open(); 

OracleCommand cmd = _conn.CreateCommand(); 
cmd.CommandText = "some_package.ins_test"; 
cmd.CommandType = CommandType.StoredProcedure; 

OracleParameter p1 = new OracleParameter(); 
OracleParameter p2 = new OracleParameter(); 

p1.OracleDbType = OracleDbType.Decimal; 
p1.Direction = ParameterDirection.Input; 
p2.OracleDbType = OracleDbType.Decimal; 
p2.Direction = ParameterDirection.Output; 

p1.CollectionType = OracleCollectionType.PLSQLAssociativeArray; 
p1.Value = new int[3] { 1, 2, 3 }; 
p1.Size = 3; 

cmd.Parameters.Add(p1); 
cmd.Parameters.Add(p2); 

cmd.ExecuteNonQuery();
