详解Pymongo常用查询方法总结

import pymongo
def operating_mongodb():
  client = pymongo.MongoClient('ip_address', port)
  db_auth = client.database
  db_auth.authenticate("username", "password")
  db = client.db_name
  return db

mongodb = operating_mongodb()
search_set = mongodb.table_name

search_set.find().sort("field_name ",pymongo.ASCENDING)   --升序
search_set.find().sort("field_name ",pymongo.DESCENDING)  --降序

search_set.find({“field_name”:”value”})
search_set.find({“field_name”:”value”, “field_name”:”value”})

search_set.find({}, {“field_name_one”:1, “field_name_two”:1,”_id”:0})

search_set.find({"field_name": {"$lt": value, "$gt": value}})

search_set.find({"field_name": {"$in": [1,5,8]}})

search_set.find({"field_name": {"$nin": [5]}})

search_set.find({"$or": [{"field_name": {'$regex': value}},{"field_name": {'$regex': value}}]})
