No data for 100YWeatherSmall

Hi, i am unable to find dataset for day 3 quiz Element Operation.

MongoDB Enterprise Cluster0-shard-0:PRIMARY> use 100YWeatherSmall
switched to db 100YWeatherSmall
MongoDB Enterprise Cluster0-shard-0:PRIMARY>{atmosphericPressureChange: {$exists: false}}).count(


First of all it didn’t access the collections properly, how you connected to this atlas cluster…is it through -username m001-student ( i mean the M001 atlas cluster)???

yes… as per guidelines mentioned in the video

I am able to get the output. Please use the below command to connect to our atlas cluster:

mongo "mongodb://,," --authenticationDatabase admin --ssl --username m001-student --password m001-mongodb-basics

Also, I am assuming you have closed the paranthesis for count, it is count(). So, your query will look like:{atmosphericPressureChange: {$exists: false}}).count()
