What's the Most Efficient Way to Implement JDBC Pagination?

JDBC Pagination with Optimal Efficiency

Pagination in JDBC involves retrieving a limited number of records from a database in a sequential manner to display data on multiple pages. To achieve this, one commonly thinks of scrolling through results using rs.absolute(row) to skip records for subsequent pages. However, this approach can be inefficient for large result sets.

Instead, the most efficient method for pagination in JDBC is to construct SQL queries with limit and offset parameters. These parameters specify the number of records to retrieve and the starting position in the result set, respectively. For example, the query "SELECT FROM data LIMIT 50 OFFSET 0" would retrieve the first 50 records from the "data" table, while the query "SELECT FROM data LIMIT 50 OFFSET 50" would retrieve the next 50 records for page 2.

However, it is important to note that using limit and offset parameters can have varying levels of efficiency depending on the underlying database. Some databases, such as MySQL, implement limit and offset efficiently, while others, such as Oracle, may require more complex subqueries to achieve pagination.
