problem with data processing OracleDataReader (OracleRefCursor)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
i need help, when i get the data of procedure BD (Oracle). I do not know how to deal with data type date time, int etc. I only know do with strings
public static Player_E getPlayer(string select)
{
Player_E player = new Player_E();
DateTime? dateTime = new DateTime();
conexion = bd.ConexionWithDB();
orden.CommandText = "CONSULTAS.obtener_jugador";
orden.CommandType = CommandType.StoredProcedure;
orden.Parameters.Add("v_nombre", OracleDbType.Varchar2, 60).Value = select;
orden.Parameters.Add("jugadores_dev", OracleDbType.RefCursor, DBNull.Value, ParameterDirection.Output);
orden.Parameters.Add("c2blob", OracleDbType.Blob).Direction = ParameterDirection.Output;
orden.Connection = conexion;
orden.ExecuteNonQuery();
OracleDataReader dr = ((OracleRefCursor)orden.Parameters["jugadores_dev"].Value).GetDataReader();
dr.Read();
//tbNombre.Text = dr["c1"].ToString();
OracleBlob blob = (OracleBlob)orden.Parameters["c2blob"].Value;
byte filedata = null;
if (blob.Length != 0)
{
filedata = new byte[blob.Length];
}
//these are attempts that I have been making
//dateTime = Convert.ToDateTime(dr["d1"].ToString());
//dateTime = Convert.ToDateTime(dr.GetOrdinal("d1").ToString());
//dateTime = dr["d1"].ToString().Length > 0 ? DateTime.Parse(dr["d1"].ToString()) : DateTime.MinValue;
//dateTime = DateTime.ParseExact(dr["d1"].ToString(),"dd/MM/yyyy",System.Globalization.CultureInfo.CreateSpecificCulture("es-ES"));
player = new Player_E (dr["c1"].ToString(), dr["c2"].ToString(), dr["c3"].ToString(), dateTime, dr["c4"].ToString(), filedata);
//dr.Dispose();
//orden.Dispose();
conexion.Close();
return player;
}
Here is the method where i call for the send the object Player with the values.
Edit: This is the Procedure:
PROCEDURE OBTENER_JUGADOR (v_nombre VARCHAR2,
est_jugador OUT estructura_devuelta,
C2BLOB OUT BLOB)
IS
BEGIN
INSERT INTO TMP_ESTRUCTURA (c1,
c2,
c3,
d1,
c4)
SELECT NOMBRE,
DIRECCION,
PUESTO_HAB,
FECHA_NAC,
EQUIPO_JUGADOR
FROM jugador
WHERE nombre = v_nombre;
SELECT FOTO_JUGADOR
INTO C2BLOB
FROM jugador
WHERE nombre = v_nombre;
OPEN est_jugador FOR SELECT * FROM TMP_ESTRUCTURA;
EXCEPTION
WHEN OTHERS
THEN
raise_application_error (
-20100,
'El jugador ' || v_nombre || ' no existe' || SQLERRM);
END OBTENER_JUGADOR;
Thanks for all

Hi, thanks for comment, i using Oracle.ManagedDataAccess.Client; and i trieddr.GetString(0);
all values is string, (0,1,2,3,4,5) all is string and value null. The structure is string,string,string,date,string,blob. and i get all this for procedure.

This type library also hasOracleDataReader.GetDateTime()
andOracleDataReader.GetOracleDate()
, why are you not trying/using those?

Nov 16 '18 at 19:27
I was usedwhile(dr.Read()) { name = dr.GetString(0); ... ... dateTime = dr.GetDateTime(0) }
and the value is null but when i use with name = dr["c1"].ToString(); the value isn`t null

I've tried again in case I was wrong before and it's the same result. The error is -> the column have data null Unhandled exception of type 'System.InvalidCastException' in Oracle.ManagedDataAccess.dll. the code isjugador = new Jugador_E(dr.GetString(0), dr.GetString(1), dr.GetString(2), dr.GetDateTime(3), dr.GetString(4), filedata);
