c# - 参数的数量与存储过程的值的数量不匹配

Question

我正在使用 Enterprise Library 5x DAAB 调用带有一个输入参数和一个输出参数的 Oracle 存储过程。但它给出了这个错误:

The number of parameters does not match number of values for stored procedure

我的代码如下:

OracleDatabase _database;
OracleConnection _connection;
...
...
DbCommand insertCommand = _database.GetStoredProcCommand("spName");
insertCommand.Connection = _connection;    
_database.AddInParameter(insertCommand, "inParam", DbType.Int16);
_database.AddOutParameter(insertCommand, "outParam", DbType.Byte, 1);
insertCommand.Prepare();

object[] paramValues = new object[] { 1, 2  };
_database.AssignParameters(insertCommand, paramValues);
_database.ExecuteNonQuery(insertCommand, _transaction);
int outParamVal = (int)_database.GetParameterValue(insertCommand, "outParam");

请注意:以上代码是完整源代码的一个小型示例。但描述了类似的功能。

这是我正在使用的 SP:

所以，目前似乎没有解决方案。所以暂时，我通过以下方式完成了我的工作。非常基本的东西..

...
...
OracleConnection _connection = _dbConnect.OpenOracleDB();   //custom API to get the Connection object
OracleTransaction transaction = _connection.BeginTransaction();
int affectedRows = 0;
OracleCommand insertCommand = new OracleCommand("MyProc", _connection, transaction);
using (insertCommand)
{
    insertCommand.CommandType = CommandType.StoredProcedure;
    OracleParameter param1 = new OracleParameter("PARAM1", OracleType.Number);
    param1.Direction = ParameterDirection.Input;
    insertCommand.Parameters.Add(param1);
    OracleParameter param2 = new OracleParameter("PARAM2", OracleType.Number);
    param2.Direction = ParameterDirection.Input;
    insertCommand.Parameters.Add(param2);
    OracleParameter outParam = new OracleParameter("OUTPARAM", OracleType.Int32);
    outParam.Size = 1;
    outParam.Direction = ParameterDirection.Output;
    insertCommand.Parameters.Add(outParam);                    

    insertCommand.Prepare();

    foreach (MyObject myObject in myObjects)    //myObjects is a list of objects I want to persist
    {
        param1.Value = myObject.Prop1;
        param2.Value = myObject.Prop2;

        insertCommand.ExecuteNonQuery();
        affectedRows = Convert.ToInt32(outParam.Value);
    }

    transaction.Commit();
}
...

据我统计，您的存储过程有 30 个输入参数和 1 个输出参数。如果你想让它运行，你将需要提供你的过程需要的所有 30 个输入参数。
