android - 如何在cloudant查询中对日期进行排序

Question

我想在本地 cloudant 查询中按降序日期对数据进行排序。 我的数据库文档中有 insert_ts 。 我的简单查询代码是:-

  public List<BasicDocumentMAP> allTasksWithAllArg(Map<String, Object> query, int skip, int limit, List<String> fields, List<Map<String, String>> sortDocument) {
    int nDocs = this.sunDatastore.getDocumentCount();
    QueryResult all = this.im.find(query, skip, limit, fields, sortDocument);
    List<BasicDocumentMAP> arrayListBasicDocumentMAP = new ArrayList<>();

    // Filter all documents down to those of type Task.
    for (DocumentRevision rev : all) {

    }}

请帮助我按日期对数据进行排序。谢谢

试试这个代码:

Sql查询:

Select  _id ,  _rev ,  insert_ts ,  title from table
where year=2010 order by insert_ts

Cloudant 查询:

{
  "selector": {
    "year": {
      "$gt": 2010
    }
  }, 
  "fields": ["_id", "_rev", "insert_ts", "title"], // 
  "sort": [{"insert_ts": "asc"}]
}
