Question

在oracle 12C数据库中创建了一个包，并使用C＃代码来调用它。得到错误＆＃34;错误的参数数量或类型＆＃34;当executeNoQuery如下所示。检查包签名并与C＃中的代码进行比较。无法弄清楚这个问题。唯一不确定的类型是映射Oracle编号（10）。试图用OracleDbType.varchar2，int32，int64和Long映射它，但得到了所有相同的错误。下面是包签名和C＃代码。我想知道我做了什么有什么不对，有人可以提供帮助。

包装：

create or replace PACKAGE GETIMPOSITION AS    
   TYPE impTyp IS TABLE OF varchar2(200);
   TYPE impNm IS TABLE OF varchar2(255);  
   TYPE impTax IS TABLE OF char(1);
   TYPE impIncld IS TABLE OF char(1);
   TYPE impId IS TABLE OF varchar2(8);
   TYPE impSkuId IS TABLE OF number(10,0);
   TYPE impPmCd IS TABLE OF varchar2(15);

   /* Get data from each OUT parameter */
   procedure RMS_GET_IMPOSITION_INFO (
      O_IMPOSITIONTYPES OUT impTyp,
      O_ERRORDES OUT VARCHAR2,
      O_ERRORCODE OUT VARCHAR2
   ); 
END GETIMPOSITION;

C＃代码：

 int[] aRraybindingSize = new int[2000];
    List<string> empty = new List<string>();
    for (int i = 0; i < arrBindingSize.Length; i++)
    {
       empty.Add(string.Empty);
    }

    using (OracleConnection database = new OracleConnection(connString))
    {
    OracleCommand dbCommand = database.CreateCommand();
    dbCommand.CommandType = System.Data.CommandType.StoredProcedure;
    dbCommand.CommandText = ConfigurationManager.AppSettings.Get("StoredProcedureNameIMPSEX");

    OracleParameter[] oracleParam = new OracleParameter[3];
    oracleParam[0] = new OracleParameter("O_IMPOSITIONTYPES", OracleDbType.Varchar2, 100);
    oracleParam[0].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[0].Direction = ParameterDirection.Output; 
    oracleParam[0].Size = empty.Count;
    oracleParam[0].ArrayBindSize = arrBindingSize;
    for (int i = 0; i < arrBindingSize.Length; i++)
    {
        oracleParam[0].ArrayBindSize[i] = 100;
    }
    oracleParam[0].Value = empty.ToArray();
    dbCommand.Parameters.Add(oracleParam[0]);

oracleParam [1] =新的OracleParameter（＆＃34; O_ERRORDES＆＃34;，OracleDbType.Varchar2,512）; oracleParam [1] .Direction = System.Data.ParameterDirection.Output;

    oracleParam[2] = new OracleParameter("O_ERRORCODE", OracleDbType.Varchar2, 512);
    oracleParam[2].Direction = System.Data.ParameterDirection.Output;

    dbCommand.Parameters.AddRange(oracleParam);
    database.Open();
    int status = dbCommand.ExecuteNonQuery(); 
 }

更改过程只有一个OUTPUT数组（如上所示）但仍然有相同的错误。如果将其更改为不是数组，则过程和C＃代码从数据库调用中获取正确的数据。对于我来说，在C＃代码谈话过程中，他们并不了解PLSQLAssociativeArray是什么。添加状态作为返回参数不是问题。这不是oracle函数调用。没有返回值的executeNonQuery很好，所以行int状态可以消失。对PLSQLAssociativeArray有何评论？是任何错误。还是程序需要改变？

首先尝试添加状态参数

create or replace PACKAGE GETIMPOSITION AS    
   TYPE impTyp IS TABLE OF varchar2(200);
   TYPE impNm IS TABLE OF varchar2(255);  
   TYPE impTax IS TABLE OF char(1);
   TYPE impIncld IS TABLE OF char(1);
   TYPE impId IS TABLE OF varchar2(8);
   TYPE impSkuId IS TABLE OF number(10,0);
   TYPE impPmCd IS TABLE OF varchar2(15);

   /* Get data from each OUT parameter */
   procedure RMS_GET_IMPOSITION_INFO (
      O_IMPOSITIONTYPES OUT impTyp,
      O_IMPOSITIONNAME OUT impNm,
      O_IMPSTTAXABILITIES OUT impTax,
      O_INCLUDEDINTAXES OUT impIncld,
      O_IMPOSITIONID OUT impId,
      O_IMPSTSKUS OUT impSkuId,
      O_IMPSTPIMS OUT impPmCd,
      O_ERRORDES OUT VARCHAR2,
      O_ERRORCODE OUT VARCHAR2
   ); 
END GETIMPOSITION;



    int[] aRraybindingSize = new int[2000];

    using (OracleConnection database = new OracleConnection(connString))
    {
    OracleCommand dbCommand = database.CreateCommand();
    dbCommand.CommandType = System.Data.CommandType.StoredProcedure;
    dbCommand.CommandText = ConfigurationManager.AppSettings.Get("StoredProcedureNameIMPSEX");

// Return value parameter has to be added first !
                int status = new OracleParameter();
                status.Direction = ParameterDirection.ReturnValue;
                status.OracleDbType = OracleDbType.Int32;
                cmd.Parameters.Add(status);

    OracleParameter[] oracleParam = new OracleParameter[9];
    oracleParam[0] = new OracleParameter("O_IMPOSITIONTYPES", OracleDbType.Varchar2, 100);
    oracleParam[0].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[0].Direction = ParameterDirection.Output;
    oracleParam[0].ArrayBindSize = aRraybindingSize;

    oracleParam[1] = new OracleParameter("O_IMPOSITIONNAME", OracleDbType.Varchar2, 255);
    oracleParam[1].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[1].Direction = ParameterDirection.Output;
    oracleParam[1].ArrayBindSize = aRraybindingSize;

    oracleParam[2] = new OracleParameter("O_IMPSTTAXABILITIES", OracleDbType.Char, 1);
    oracleParam[2].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[2].Direction = ParameterDirection.Output;
    oracleParam[2].ArrayBindSize = aRraybindingSize;

    oracleParam[3] = new OracleParameter("O_INCLUDEDINTAXES", OracleDbType.Char, 1);
    oracleParam[3].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[3].Direction = ParameterDirection.Output;
    oracleParam[3].ArrayBindSize = aRraybindingSize;

    oracleParam[4] = new OracleParameter("O_IMPOSITIONID", OracleDbType.Varchar2, 8);
    oracleParam[4].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[4].Direction = ParameterDirection.Output;
    oracleParam[4].ArrayBindSize = aRraybindingSize;

    oracleParam[5] = new OracleParameter("O_IMPSTSKUS", OracleDbType.Int64);
    oracleParam[5].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[5].Direction = ParameterDirection.Output;
    oracleParam[5].Precision = 10;
    oracleParam[5].Scale = 0;
    oracleParam[5].Size = 10;
    oracleParam[5].ArrayBindSize = aRraybindingSize;

    oracleParam[6] = new OracleParameter(`enter code here`"O_IMPSTPIMS", OracleDbType.Varchar2, 15);
    oracleParam[6].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
    oracleParam[6].Direction = ParameterDirection.Output;
    oracleParam[6].ArrayBindSize = aRraybindingSize;

    oracleParam[7] = new OracleParameter("O_ERRORDES", OracleDbType.Varchar2, 512);
    oracleParam[7].Direction = System.Data.ParameterDirection.Output;

    oracleParam[8] = new OracleParameter("O_ERRORCODE", OracleDbType.Varchar2, 512);
    oracleParam[8].Direction = System.Data.ParameterDirection.Output;

    dbCommand.Parameters.AddRange(oracleParam);
    database.Open();
    Convert.ToInt32(status.Value) = dbCommand.ExecuteNonQuery(); 

 }
