Implementing result paging in hibernate (getting total number of rows)

Question

How do I implement paging in Hibernate? The Query objects has methods called setMaxResults and setFirstResult which are certainly helpful. But where can I get the total numb

Answer 1

You can just setMaxResults to the maximum number of rows you want returned. There is no harm in setting this value greater than the number of actual rows available. The problem the other solutions is they assume the ordering of records remains the same each repeat of the query, and there are no changes going on between commands.

To avoid that if you really want to scroll through results, it is best to use the ScrollableResults. Don't throw this object away between paging, but use it to keep the records in the same order. To find out the number of records from the ScrollableResults, you can simply move to the last() position, and then get the row number. Remember to add 1 to this value, since row numbers start counting at 0.
