public class BatchUpdateException
extends SQLException

The subclass of SQLException thrown when an error occurs during a batch update operation. In addition to the information provided by SQLException, a BatchUpdateException provides the update counts for all commands that were executed successfully during the batch update, that is, all commands that were executed before the error occurred. The order of elements in an array of update counts corresponds to the order in which commands were added to the batch.

After a command in a batch update fails to execute properly and a BatchUpdateException is thrown, the driver may or may not continue to process the remaining commands in the batch. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will have an element for every command in the batch rather than only elements for the commands that executed successfully before the error. In the case where the driver continues processing commands, the array element for any command that failed is Statement.EXECUTE_FAILED.

1.2

Method Detail

getUpdateCounts

public int[] getUpdateCounts()

Retrieves the update count for each update statement in the batch update that executed successfully before this exception occurred. A driver that implements batch updates may or may not continue to process the remaining commands in a batch when one of the commands fails to execute properly. If the driver continues processing commands, the array returned by this method will have as many elements as there are commands in the batch; otherwise, it will contain an update count for each command that executed successfully before the BatchUpdateException was thrown.

The possible return values for this method were modified for the Java 2 SDK, Standard Edition, version 1.3. This was done to accommodate the new option of continuing to process commands in a batch update after a BatchUpdateException object has been thrown.

Returns:

an array of int containing the update counts for the updates that were executed successfully before this error occurred. Or, if the driver continues to process commands after an error, one of the following for every command in the batch:

1. an update count
2. Statement.SUCCESS_NO_INFO to indicate that the command executed successfully but the number of rows affected is unknown
3. Statement.EXECUTE_FAILED to indicate that the command failed to execute successfully

1.3
