PreparedStatement.executeBatch() and BatchUpdateException

Question

Hi,
I am using PreparedStatement's executeBatch() method to make batch operations,
for such a scenario is there a way to continue the operation 3 and 4 when the operation 2 fails?
operation 1 (will succeed alone)
operation 2 (will fail alone)
operation 3 (will succeed alone)
operation 4 (will succeed alone)

Answer 1

Hi, I've already looked the link you've sent.
Let me give more detail about the result of my scenario.
The first two successfull insert operations really updates the database which is Oracle.
But it seems the failed 3rd operation prevents the operation 4 to update database.
My code is something like that:
int[] updateCounts = null;
try {
PreparedStatement stmtInsert = conn.prepareStatement("insert sql");
for (int i=0; i <SOMEVALUE; i++)
     stmtInsert.setString(1, SOMEVALUE);
     stmtInsert.setString(2, SOMEVALUE);
     stmtInsert.addBatch();
int[] counts = stmtInsert.executeBatch();
} catch (BatchUpdateException e)
updateCounts = e.getUpdateCounts();
checkUpdateCounts(updateCounts);
finally {
conn.close();
public static void checkUpdateCounts(int[] updateCounts) {
for (int i = 0; i < updateCounts.length; i++) {
if (updateCounts[i] == Statement.SUCCESS_NO_INFO) {
// Successfully executed; number of affected rows not available
System.out.println("Statement.SUCCESS_NO_INFO");
} else if (updateCounts[i] == Statement.EXECUTE_FAILED) {
System.out.println("Statement.EXECUTE_FAILED");
The results are pretty confusing, as I said first two operations updates the db, but fourth is did not.
But system out says:
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
I would expect something like that:
Statement.SUCCESS_NO_INFO");
Statement.SUCCESS_NO_INFO");
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
or even better (assuming operation 4 updated the db)
Statement.SUCCESS_NO_INFO");
Statement.SUCCESS_NO_INFO");
Statement.EXECUTE_FAILED
Statement.SUCCESS_NO_INFO");
Since the size of the int array that the e.getUpdateCounts() is 4 which is also equal of the batch operations' size, I assume that the driver continues to process the commands in the batch after a BatchUpdateException is thrown.
I am totally confused, can anybody comment these results? Is there a way to succeed the fourth operation?
