ORA-28094: SQL Construct not Supported by Data Redaction

Hi,

Sometimes You can get ”  ora-28094: sql construct not supported by data redaction  ” error.

 

Details of error are as follows.

ora-28094: sql construct not supported by data redaction

with table2 AS (
 Select concat(card_no,' ') from payment_details )
 select *  from table2;//This is giving 'ORA-28094: SQL construct not supported by data redaction' error
 
 with table2 AS (
 Select sum(card_no) from payment_details )
 select *  from table2;//This is giving 'ORA-28094: SQL construct not supported by data redaction' error
 
 
 with table2 AS (
 Select trim(card_no) from payment_details )
 select *  from table2;//This is giving 'ORA-28094: SQL construct not supported by data redaction' error

 

 

As per Bug 26577695 / bug 24340261, the ORA-28094 error raised in 12.2 is expected behavior. Because the query has construct “concat()” on a redacted column called from within a view is not supported by Data Redaction.

This change in behavior is caused by fix of Bug 22537972.

In future, we have plan to support such queries, for that please  watch bug 24340261.

The current 12.2 behavior is expected behavior

There is another fix of bug 27697108 which doesn’t block the user with EXEMPT  REDACTION POLICY system privilege.
