Question

Hi I am trying to understand how to convert java code to C#, I read some tutorials about java but I dont find the way in how to translate this lines of code:

CallableStatement cstmt = con.prepareCall("?=CALL
cstmt.registerOutParameter(1, Types.JAVA_OBJECT);
cstmt.execute(); 
ResultSet rs = (ResultSet) cstmt.getObject(1); 

I try with

  CUBRIDConnection con = new CUBRIDConnection(ConnectionString);
  CUBRIDCommand com = new CUBRIDCommand();
  com.CommandType = CommandType.StoredProcedure;
  com.Connection = con;
  com.CommandText = "call mySP();";
  com.Parameters.Add("?=p", CUBRIDDataType.CCI_U_TYPE_RESULTSET).Direction =
      ParameterDirection.Output;
  con.Open();
  DbDataReader df = com.ExecuteReader(CommandBehavior.SingleResult);
  //some stuff
  con.Close();

This dont work, how can I translate it?

Answer 1

try this

 SqlConnection con = new SqlConnection("your connection string");
    SqlCommand com = new SqlCommand();
    com.CommandType = CommandType.StoredProcedure;
    com.Connection = con;
    com.CommandText = "yourstoredprocedurename"; //no paranthesis or call key word just procedure name
    SqlParameter parameter = new SqlParameter("yourparametername", SqlDbType.Binary); //just parameter name no questionmark
    parameter.Direction= ParameterDirection.Output;
    com.Parameters.Add(parameter);
    con.Open();
    var df = com.ExecuteReader(CommandBehavior.SingleResult);
    //some stuff
    con.Close();
