如何使用 Python 更新 Cosmos 表 API 中实体的属性

Question

I have the below table in CosmosDB.

PartitionKey  Rowkey  Group  Salary
John          HR      A      100000
Mark          DOC     B      200000

I want to update the Salary property in the first entity. When I tried to update the salary property in the first entity, the complete entity is being replaced instead of updating the salary property.

Could someone let me know how to update an property in a entity in CosmosDB table API.

from azure.data.tables import TableServiceClient
from datetime import datetime


my_entity = {
   "PartitionKey" : "John",
    "RowKey" : "HR",
    "Group": "A",
    "Salary": 100000
  
}
table_service_client = TableServiceClient.from_connection_string(conn_str="")
table_client = table_service_client.get_table_client(table_name="my_table")

entity = table_client.create_entity(entity=my_entity)


created = table.get_entity(partition_key=my_entity["PartitionKey"], row_key=my_entity["RowKey"])
created["Salary"] = "200"
table.update_entity(mode=UpdateMode.REPLACE, entity=created)

Answer 1

Please try by changing the following lines of code:

created = table.get_entity(partition_key=my_entity["PartitionKey"], row_key=my_entity["RowKey"])
created["Salary"] = "200"
table.update_entity(mode=UpdateMode.REPLACE, entity=created)

with

created = table_client.get_entity(partition_key=my_entity["PartitionKey"], row_key=my_entity["RowKey"])
created["Salary"] = "200"
table_client.update_entity(mode=UpdateMode.MERGE, entity=created)
