In the CosmosDB module, I see commands to create a context. Is there one to update an existing context ?

Thanks,

Hi @Kothai Ramanathan , welcome to Microsoft Q&A forum.

We create a context object by passing the necessary details to be able to connect to Cosmos DB like account name, database name, key values. We cannot directly update the context object but can override it by initiating a new command like the one used for creation.

Please refer to below links on the PowerShell command:
New-CosmosDbContext
CosmosDB PowerShell Module

Please let me know if this helps or we can discuss further.

@AnuragSharma-MSFT - sorry guess I have not worded my question correctly. I see a New-CosmosDbDocument command. This one creates a new document correctly. However, if the document is already existing it not update. So wanted to know if there is an equivalent command (like Update-CosmosDbDocument) to update an existing document. Thanks.

Hi @Kothai Ramanathan , yes we can do that by using Set-CosmosDbDocument command. Please check the below commands:

1). Retrieve the document:

$document = Get-CosmosDbDocument -Context $cosmosDbContext -CollectionId 'MyNewCollection' -Id 'ac12345' -ConsistencyLevel Strong

2) Update the property:

$newDocument = @" { "id": "$($document.id)", "counter": $($document.counter + 1) } "@

3) Update the document:

Set-CosmosDbDocument -Context $cosmosDbContext -CollectionId 'MyNewCollection' -Id 'ac12345' -DocumentBody $newDocument -Encoding 'UTF-8' -ETag $document._etag

I used commands from below article. You might need to change it accordingly but this will help you in updating the documents.
Set-CosmosDbDocument

Please let me know if this helps.
