Query.executeAndFetchLazy介绍

[英]Read a collection lazily. Generally speaking, this should only be used if you are reading MANY results and keeping them all in a Collection would cause memory issues. You MUST call org.sql2o.ResultSetIterable#close() when you are done iterating.
[中]懒洋洋地读一本藏书。一般来说，只有当你正在阅读许多结果，并且将它们全部保存在一个集合中会导致内存问题时，才应该使用这个选项。你必须打电话给org。sql2o。迭代完成后，ResultSetTable#close（）将自动关闭。

代码示例

public ResultSetIterable<ArchiveEntry> findArchivesForIndex(Connection con, IndexEntry indexEntry)
{
  return con.createQuery("select archive.id, archive.archiveId, archive.nameHash,"
    + " archive.crc, archive.revision, archive.hash from index_archive "
    + "join archive on index_archive.archive = archive.id "
    + "where index_archive.index = :id")
    .addParameter("id", indexEntry.getId())
    .executeAndFetchLazy(ArchiveEntry.class);
}
