Предаване на масив към процедурата на Oracle от c#

Дефинирайте тип масив и процедура:

CREATE or replace PACKAGE Testpackage AS 
  TYPE Areas_t is table of VARCHAR(100) index by BINARY_INTEGER;
  PROCEDURE TESTPROCEDURE(Areas IN Areas_t);       
END Testpackage; 

C# рутина:

public void InsertQuestion(IEnumerable<string> area_list)
{
    var connect = new OracleConnection("YOUR CONNECTION STRING");

    var command = new OracleCommand("BEGIN Testpackage.Testprocedure(:Areas); END;", connect);

    connect.Open();

    var arry = command.Parameters.Add("Areas", OracleDbType.Varchar2);

    arry.Direction = ParameterDirection.Input;
    arry.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    arry.Value = area_list.ToArray();
    arry.Size = area_list.Count();
    arry.ArrayBindSize = area_list.Select(_ => _.Length).ToArray();
    arry.ArrayBindStatus = Enumerable.Repeat(OracleParameterStatus.Success, area_list.Count()).ToArray();

    command.ExecuteNonQuery();

    connect.Close();
