C＃和Oracle 10g数据库调用存储过程

问题描述：

我是一个C＃+ SQL Server数据库开发人员。

I am a C# + SQL server database developer.

现在我使用的甲骨文作为数据库。我有一个Oracle存储过程的重新调整参考光标。

Now I am using Oracle as a database. I have one Oracle stored procedure retuning ref cursor.

CREATE OR REPLACE PROCEDURE Get_Trans_Data ( p_return_cur OUT SYS_REFCURSOR)
IS

BEGIN
  OPEN p_return_cur FOR
  select * from test_tbl1 ;
END Get_Trans_Data;

使用OLEDB我只怎么可以访问此存储过程并保存导致数据集？

Using Oledb only how can I access this stored proc and save result in dataset?

我没有得到在OLEDB REF CURSOR数据类型的选项。

I am not get the option for ref cursor datatype in Oledb.

答

您可以尝试这样的事。无需添加参数OUT的。了解更多这里

You can try something like this. No need to add parameter for OUT's. Read more here

static void Read()
{
    using (var currentConnection = new OleDbConnection(
        "provider=MSDAORA;Data Source=orcl;User ID=db_test;Password=db_test;"))
    {

        currentConnection.Open();
        using (var myCommand = new OleDbCommand())
        {
            myCommand.Connection = currentConnection;
            myCommand.CommandType = CommandType.StoredProcedure;
            myCommand.CommandText = "Get_Data";

            myCommand.Parameters.Add(
                new OleDbParameter(
                    "firstParam",
                    OleDbType.Integer, 0, ParameterDirection.Input,
                    true, 0, 0, "", DataRowVersion.Default, Convert.DBNull));

            myCommand.Parameters[0].Value = 42;

            var myDataReader = myCommand.ExecuteReader();
            while (myDataReader.Read())
                for (int i = 0; i < myDataReader.FieldCount; i++)
                    Console.WriteLine(myDataReader.GetName(i));
        }
    }
}

CREATE OR REPLACE PROCEDURE Get_Data (
   p_return_cur OUT SYS_REFCURSOR,
   firstParam INTEGER) 
IS 
BEGIN 
  OPEN p_return_cur FOR select * from test; 
END Get_Data;
