如何从 GCP 的结算 UI 中删除标签？

Question

In Google Cloud Platform, you can add labels to several resources and also add labels to the query jobs you execute . I did this second option. A typical code looks like this:

bq query --label=my_label:{parameter} --label=my_label2:{parameter2} --format=json --use_legacy_sql=false '{query}'"

But, by mistake, the first time I did like this:

bq query --label=my_label{parameter} --label=my_label2:{parameter2} --format=json --use_legacy_sql=false '{query}'"

which created several jobs (I regularly ran this command) having a label named my_labelFoo with an empty value instead of a label named my_label with a value of Foo . This was detected when, in the Billing UI, we noticed several labels as options for filtering, being all of them:

my_labelFoo my_labelBar my_labelBaz my_labelJohn my_labelGeorge my_labelRingo my_labelPaul...

What I tried to do, then, is to delete the metadata of those wrong jobs. So I tried this query in BigQuery (having the appropriate permissions):

SELECT job_id, query, labels FROM `my-project`.`region-us`.INFORMATION_SCHEMA.JOBS_BY_PROJECT WHERE ARRAY_LENGTH(labels) > 0 AND EXISTS(SELECT * FROM UNNEST(labels) l WHERE l.key = 'my_labelRingo')"

For each job_id retrieved this way, I tried invoking:

from google.cloud.bigquery import Client
Client().delete_job_metadata(job_id, location="us")

What I can say for good, is that the job entries were removed (they were a few amount), but...

...when I go back to the Billing UI, I still see the my_labelRingo as a selectable label from there . I don't want that label to exist anymore.

So, my question is:

• How do I delete the wrong labels from the Billing UI?
• Is there, perhaps, a time I have to wait for my_labelRingo to cease to exist?

Answer 1

The situation you are experiencing with the labels in the Billing console is something specific to Cloud Billing Support and you will need to directly engage them using this link so they can fully investigate why it is happening.

The solutions shared below are different alternatives to delete labels in the GCP BigQuery console.

You can delete a table or view label in the following ways:

1. Using the console

2. Using SQL DDL statements

3. Using the bq command-line tool's bq update command

4. Calling the tables.patch API method

• Because views are treated like table resources, tables.patch is used to modify both views and tables.

5. Using the client libraries

But you would need to have the next permissions:

• bigquery.tables.get

• bigquery.tables.update

For example to delete a label through the console you need to follow the next steps:

1. On the console, select the dataset you want to edit.

2. Click on the details tab and then click the pencil icon to the right of labels.

3. On the edit labels dialog

• For each label you want to delete, click delete (X)

• Click on update to save the changes,
