Executing "select * from dba_audit_trail" by clicking on the "execute statement" or "execute as script" button, returns "DATA TYPE IS NOT SUPPORTED" as error message.
There is also a problem viewing data of the table SYS.DBA_AUDIT_TRAIL in the Schema Browser:
Columns SQL_TEXT and SQL_BIND are NULL and this is wrong.
Executing select SQL_TEXT ,SQL_BIND from SYS.DBA_AUDIT_TRAIL in SQL Plus returns the correct data and it doesn't appear any error message.
