OracleInfoMessageEventArgs Class

The OracleInfoMessageEventArgs class provides event data for the OracleConnection.InfoMessage event. When any warning occurs in the database, the OracleConnection.InfoMessage event is triggered along with the OracleInfoMessageEventArgs object that stores the event data.

Class Inheritance

System.Object

  System.EventArgs

    Oracle.DataAccess.Client.OracleInfoMessageEventArgs

Declaration

// C#
public sealed class OracleInfoMessageEventArgs

Thread Safety

All public static methods are thread-safe, although instance methods do not guarantee thread safety.

Example

// C#
 
using System;
using System.Data;
using Oracle.DataAccess.Client; 
using Oracle.DataAccess.Types;
 
 
class InfoMessageSample
{
  public static void WarningHandler(object src, 
    OracleInfoMessageEventArgs args)
  {
      Console.WriteLine("Source object is: " + src.GetType().Name);
      Console.WriteLine("InfoMessageArgs.Message is " + args.Message);
      Console.WriteLine("InfoMessageArgs.Source is " + args.Source);
  }
  static void Main()
  {
    OracleConnection con = new OracleConnection("User Id=scott;" + 
      "Password=tiger;Data Source=oracle;");
 
    con.Open();
 
    OracleCommand cmd = con.CreateCommand();
 
    //Register to the InfoMessageHandler
    cmd.Connection.InfoMessage += 
      new OracleInfoMessageEventHandler(WarningHandler);
 
    cmd.CommandText = 
      "create or replace procedure SelectWithNoInto( " +
      "  empname in VARCHAR2) AS " +
      "BEGIN " +
      "  select * from emp where ename = empname; " +
      "END SelectWithNoInto;";
 
    // Execute the statement that produces a warning
    cmd.ExecuteNonQuery();
 
    // Clean up
    cmd.Dispose();
    con.Dispose();
  }
}
