/**
* 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>.
* <P>
* A JDBC driver implementation should use
* the constructor {@code BatchUpdateException(String reason, String SQLState,
* int vendorCode, long []updateCounts,Throwable cause) } instead of
* constructors that take {@code int[]} for the update counts to avoid the
* possibility of overflow.
* <p>
* If {@code Statement.executeLargeBatch} method is invoked it is recommended that
* {@code getLargeUpdateCounts} be called instead of {@code getUpdateCounts}
* in order to avoid a possible overflow of the integer update count.
