/**

 * The subclass of {@link SQLException} thrown when an error

 * occurs during a batch update operation.  In addition to the

 * information provided by {@link SQLException}, a

 * <code>BatchUpdateException</code> 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.

 * <P>

 * After a command in a batch update fails to execute properly

 * and a <code>BatchUpdateException</code> 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

 * <code>BatchUpdateException.getUpdateCounts</code> 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 <code>Statement.EXECUTE_FAILED</code>.
