JDBC / Spring-执行SQL查询以获取结果的迭代器

Question

So far I have been using 'SimpleJdbcTemplate' and used a 'RowCallbackHadler' to process the whole result of the query. At the moment I would like to receive an iterator-like object, which I could query for the next table row whe interested. Is the following behaviour possible in Spring/jdbc (preferrably slpring)?

Answer 1

You can use a ResultSetExtractor instead of a RowCallbackHadler . Methods in JdbcTemplate accepting the latter will accept the former too.

Answer 2

You can try using the JdbcTemplate method queryforRowSet

public SqlRowSet queryForRowSet(String sql,
                                Object... args)
                         throws DataAccessException
