Oracle 11g: sqlplus: command to display list of tables?

select table_name from all_tables;
or the dba_tables view if you have permission (user_tables for the ones the user owns).

>>the last time the db updated?

I don't think this is available unless you are auditing the tables.

There is a last_ddl_time in all_objects (same for the DBA nad USER views) that will show the last time the object was modofied if that helps?

>>you can use ORA_ROWSCN

This is not a 100% guarantee.  It should be a good estimate though.

This pseudocolumn is useful for determining approximately when a row was last updated. It is not absolutely precise, because Oracle tracks SCNs by transaction committed for the block in which the row resides. You can obtain a more fine-grained approximation of the SCN by creating your tables with row-level dependency tracking. Refer to CREATE TABLE ... NOROWDEPENDENCIES | ROWDEPENDENCIES for more information on row-level dependency tracking.

Thank you experts,

the problem I am having is that I don't know the tables names... or have access to ERD... so, I can't run a simple query:

select table_name from all_tables

see what I mean?

I wanted to see if I could display all tables via command line...

Thanks experts...
