Question

数据库查询后，取得的排序表，在代码中这段语句是什么意思啊，感觉像是执行数据库操作的简化版。。。

运行后取得的 /** * 按树形节点查询并排序 * @return list */ public List<Category> getAll() { try { QueryRunner runner = new QueryRunner(JdbcUtils.getDataSource()); String sql = "Select * From tree d Where d.cod Like '%001%' Order By cod"; List<Category> list = (List<Category>) runner.query(sql, new BeanListHandler(Category.class)); return list; } catch (Exception e) { throw new RuntimeException(e); } }
