In This Topic

Syntax

Raises when an error occurs during a load operation.

Syntax

Visual Basic
C#

public event OracleLoaderErrorEventHandler Error

'Declaration
 
Public Event Error As OracleLoaderErrorEventHandler

Event Data

The event handler receives an argument of type OracleLoaderErrorEventArgs containing data related to this event. The following OracleLoaderErrorEventArgs properties provide information specific to this event.

Property	Description
Column	Gets column number where an error occurred.
Exception	Gets the OracleException instance that an OracleLoader throws.
Ignore	Gets or sets whether the current error will be ignored or not.
Row	Gets row number where an error occurred.

Remarks

The event handler receives an argument of OracleLoaderErrorEventArgs type containing data related to this event. The following OracleLoaderErrorEventArgs properties provide information specific to this event:

Property	Description
OracleLoaderErrorEventArgs.Column	Gets column where an error occurred.
OracleLoaderErrorEventArgs.Row	Gets row where an error occurred.
OracleLoaderErrorEventArgs.Exception	Gets OracleException object with error specific information.
OracleLoaderErrorEventArgs.Ignore	Specifies whether current error will be ignored.

Clients that want to process errors raised by the server should create an OracleLoaderErrorEventHandler delegate to listen to this event.

Example

The following sample demonstrates using the Error event. Perform the following script against the database before executing the code:

CREATE TABLE DEPT(
  DEPTNO INTEGER PRIMARY KEY,
  DNAME VARCHAR(14),
  LOC VARCHAR(13)
);

INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');
INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');
INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');
INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');
