I am having serious issues trying to get the data back from the SP. I was trying to do it like this:
OracleCommand ora_cmd = new OracleCommand(\"a6r1.PR_ABC
It seems you cannot use existing variable as output parameter, try this way instead
ora_cmd.Parameters.Add("Lc_Exito", OracleDbType.Int32).Direction = ParameterDirection.Output; ora_cmd.ExecuteNonQuery(); if (ora_cmd.Parameters["Lc_Exito"].value == 0)
