Re: A Real Dynamic Problem For Real Dynamic Developers!!

Are these tables related in any particular way? The reason I ask this is that just because each table has this column (sounds like you want to know who inserted or modified a row - a common requirement) doesn't mean that a report like you suggest means anything. Do you want a report that lists what users made changes or inserts to what tables? Then I suggest dynamically writing a Union statement.
e.g.
(select 'Table_one',user_name from table_one group by user_name) union
(select 'Table_two',user_name from table_two group by user_name) union...

Now being the lazy guy I am I would do something like this in SQLPlus:

spool myQuery
select '(select '||table_name'|| table_name,user_name from '||table_name||' group by user_name) union' from user_tables ut where exists (select 1 from user_tab_col utc where ut.table_name=utc.table_name and column_name='USER_NAME')

spool off
Then you have your query (remove the extra union at the end.
