Hi,all!
When I query on DICT_COLUMNS,I noticed some table have columns commented,some null,for example:
select clumn_name,comments from dict_columns where table_name='USER_TABLES'
it returned comments.
but on table_name='V$DATAFILE',there is no comments.
Could someone help me?
Regards!
Alan

Because some Oracle developers give comments on the tables they work and others don't.
In addition, generally speaking, there is no comment on v$ views. It seems to be an Oracle choice.
