Hi @Kaniz Fatma​ , Thank you for your response.

Are you saying that "attribute" is nothing but a column name in a table?

I was under impression that attribute is like a tag which we should create before using it against a table's column(s). Sharing my reference below -

In either way, I am confused. I have tried to execute below command as per above databricks documentation, hoping it will create attribute, but its failing. Can you pls give an example how can we create a PII tag/attribute on a set of columns in databricks table?

[In below c_phone is a column containing sensitive data in customers table]

SQL> ALTER TABLE customers ADD ATTRIBUTE pii ON c_phone

Output:

ParseException:

[PARSE_SYNTAX_ERROR] Syntax error at or near 'ATTRIBUTE'(line 1, pos 48)

== SQL ==

ALTER TABLE iotsamples.tpch.customer_events ADD ATTRIBUTE pii ON c_phone
