Delete Documents from CosmosDB based on condition through Query Explorer

Question

What\'s the query or some other quick way to delete all the documents matching the where condition in a collection?
I want something like DELETE * FROM c WHE

Answer 1

##### Here is the python script which can be used to delete data from Partitioned Cosmos Collection #### This will delete documents Id by Id based on the result set data.

Identify the data that needs to be deleted before below step

res_list = "select id from id_del"
res_id = [{id:x["id"]} 
             for x in sqlContext.sql(res_list).rdd.collect()]
config = {
   "Endpoint" : "Use EndPoint"
  "Masterkey" : "UseKey", 
      "WritingBatchSize" : "5000",
    'DOCUMENTDB_DATABASE': 'Database',
    'DOCUMENTDB_COLLECTION': 'collection-core'
}; 

for row in res_id:
# Initialize the Python DocumentDB client
  client = document_client.DocumentClient(config['Endpoint'], {'masterKey': config['Masterkey']})

# use a SQL based query to get   documents

## Looping thru partition to delete

  query = { 'query': "SELECT c.id FROM c where c.id = "+ "'" +row[id]+"'"   }
  print(query)
  options = {}
  options['enableCrossPartitionQuery'] = True
  options['maxItemCount'] = 1000
  result_iterable = client.QueryDocuments('dbs/Database/colls/collection-core', query, options)
  results = list(result_iterable)
  print('DOCS TO BE DELETED : ' + str(len(results)))
  if len(results) > 0 :
      for i in range(0,len(results)):
      #  print(results[i]['id'])
          docID = results[i]['id']
          print("docID :" + docID)
          options = {}
          options['enableCrossPartitionQuery'] = True
          options['maxItemCount'] = 1000
          options['partitionKey'] = docID
          client.DeleteDocument('dbs/Database/colls/collection-core/docs/'+docID,options=options)
          print ('deleted Partition:' +  docID)
