OracleErrorCollection Class

An OracleErrorCollection class represents a collection of all errors that are thrown by the Oracle Data Provider for .NET.

Class Inheritance

System.Object

System.ArrayList

Oracle.DataAccess.Client.OracleErrorCollection

Declaration

// C#
public sealed class OracleErrorCollection : ArrayList

Requirements

Provider	ODP.NET, Unmanaged Driver	ODP.NET, Managed Driver	ODP.NET Core
Assembly	`Oracle.DataAccess.dll`	`Oracle.ManagedDataAccess.dll`	`Oracle.ManagedDataAccess.dll`
Namespace	`Oracle.DataAccess.Client`	`Oracle.ManagedDataAccess.Client`	`Oracle.ManagedDataAccess.Client`
.NET Framework	4.5, 4.6, 4.7, 4.8	4.5, 4.6, 4.7, 4.8	4.6.1 or higher
.NET Core	-	-	2.1 or higher

Thread Safety

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

Remarks

A simple ArrayList that holds a list of OracleErrors.

If there are multiple errors, ODP.NET only returns the first error message on the stack.

Example

// C#
 
using System;
using System.Data;
using Oracle.DataAccess.Client;
 
class OracleErrorCollectionSample
{
  static void Main()
  {
    string constr = "User Id=scott;Password=tiger;Data Source=oracle";
    OracleConnection con = new OracleConnection(constr);
    con.Open();
 
    // Create an OracleCommand object using the connection object
    OracleCommand cmd = con.CreateCommand();
 
    try
    {
      cmd.CommandText = "insert into notable values (99, 'MyText')";
      cmd.ExecuteNonQuery();
    }
    catch (OracleException ex)
    {
      Console.WriteLine("Record is not inserted into the database table.");
 
      foreach (OracleError error in ex.Errors) 
      {
        Console.WriteLine("Error Message: " + error.Message);
        Console.WriteLine("Error Source: " + error.Source);         
      }
    }
  }
