Dapper Oracle Процедура ввода массива

0 голосов
/ 03 мая 2019

Используя .net core, dapper, dapper.oracle и базу данных oracle12, я просто не могу успешно вызвать процедуру с вводом массива.Я использую вход для утверждения WHERE IN.

using Dapper;
using Dapper.Oracle;
using Oracle.ManagedDataAccess.Client;

...

OracleDynamicParameters parameters = new OracleDynamicParameters();
parameters.ArrayBindCount = 3;

//this causes error PLS-00306: wrong number or types of arguments        
parameters.Add("in_num_arr", new int[] { 2,5,6 }, OracleMappingType.Int64, ParameterDirection.Input); 

//this causes app to hang without error
//parameters.Add("in_num_arr", new int[] { 2,5,6 }, OracleMappingType.Int64, ParameterDirection.Input, 3, null, null, null, null, null, OracleMappingCollectionType.PLSQLAssociativeArray); 

parameters.Add("out_refcur", OracleDbType.RefCursor, OracleMappingType.RefCursor, ParameterDirection.Output);
using (_dbConnection = new OracleConnection(_appSettings.ConnectionStrings.AppDB))
{
  var result = await _dbConnection.QueryMultipleAsync("NUM_T_PACKAGE.NUM_T_PROCEDURE", parameters, commandType: CommandType.StoredProcedure);
  return result.Read<OutputObject>().ToList(); ;
}

Пакет Oracle: 

create or replace PACKAGE num_t_package AS 
  TYPE num_t is table of NUMBER index by BINARY_INTEGER;
  PROCEDURE  num_t_procedure(in_num_arr IN num_t, out_refcur OUT SYS_REFCURSOR);       
END num_t_package; 

CREATE OR REPLACE
PACKAGE BODY NUM_T_PACKAGE AS

  PROCEDURE  num_t_procedure(in_num_arr IN num_t, out_refcur OUT SYS_REFCURSOR) AS
  BEGIN
    OPEN out_refcur FOR
      SELECT  
        name 
    FROM
        p_table
    WHERE id IN (SELECT * FROM TABLE(in_num_arr));
  END num_t_procedure;

END NUM_T_PACKAGE;
