Examples of java.sql.BatchUpdateException

java.sql.BatchUpdateException
The subclass of {@link SQLException} thrown when an erroroccurs during a batch update operation. In addition to the information provided by {@link 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.
A JDBC driver implementation should use the constructor {@code BatchUpdateException(String reason, String SQLState,int vendorCode, long []updateCounts,Throwable cause) } instead ofconstructors that take {@code int[]} for the update counts to avoid thepossibility of overflow.
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. @since 1.2
