How to add description to an existing bigquery table?

Question

I'm looking for a way to add description to an existing table attributes, is there any simple command line command such as "alter table zzz add description...." to to this?

Answer 1

You can add descriptions to tables and its fields through the web UI - that would be the simplest way.

Also via the API, using this document endpoint with the PATCH() methos:

https://cloud.google.com/bigquery/docs/reference/v2/tables

description 
schema.fields[].description 

The bq command line tool can be used too:

bq update --description "My table" existing_dataset.existing_table
