import pymongo
import datetime
#mongodbUrl = 'mongodb://test:[email protected]:27018,192.168.1.3:27018,192.168.1.3:27018'
mongodbUrl="mongodb://localhost:27017/"
dbName = "test"
myclient = pymongo.MongoClient(mongodbUrl)
mydb = myclient[dbName]
建立表並初始話索引
如果不指定索引名稱，預設使用index語句為索引名稱，如果索引過長會報
pymongo.errors.OperationFailure: exception: namespace name generated from index name "test.table01.${"imei":1,"vin":1,"startTime":1,"startTime":-1,"endTime":1,"endTime":-1,"channelld":1,"status":1}_1" is too long (127 byte max)
指令碼
table01= mydb["table01"] table01.create_index('{"imei":1,"vin":1,"startTime":1,"startTime":-1,"endTime":1,"endTime":-1,"channelld":1,"status":1}', name='table01_index')
