Question

我试图将数组传递给oracle程序。我搜索了它，首先我创建了一个名为＆＃39; dizi＆＃39; （比如enter link description here）。所以它适用于oracle开发人员。问题是;我不能将我的c＃数组作为参数传递给过程。那么如何将我的数组传递给我的程序呢？

这是我的代码（当我执行时，oracle错误说：并非所有变量都绑定）

public void InsertQuestion(List<string> area_list)
{
    quest_areas = area_list.ToArray();
    command.Connection = connect;
    connect.Open();

    var arry = command.Parameters.Add("Areas", OracleDbType.Varchar2);
    arry.Direction = ParameterDirection.Input;
    arry.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    arry.Value = quest_areas;


    command.CommandText ="TESTPROCEDURE(:Areas)";
    command.CommandType = CommandType.StoredProcedure;
    command.ExecuteNonQuery();
    connect.Close();
}

定义数组类型和过程：

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＃例程：

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();
}

从c＃传递数组到Oracle过程
