This pretty much just dumps out all non SYS-owned tables from dba_objects and has error handling for TABLEs that can't be counted (i.e., the IOT exception). Let me know your thoughts. This is crude at the moment, but you get the idea. set serveroutput on declare type tablename is table of dba_objects.object_name%type index by binary_integer; table_list tablename; indx number := 0; v_count number := 0; v_tab varchar2(256); v_sqltext varchar2(1000); begin for r_c3 in (select owner,object_name from dba_objects where object_type = 'TABLE') loop table_list(indx) := r_c3.owner||'."'||r_c3.object_name||'"'; indx := indx + 1; end loop; for xndx in table_list.first..table_list.last loop if table_list.exists(xndx) and table_list(xndx) not like 'SYS.%' then v_tab := table_list(xndx); v_sqltext := 'select count(*) from '|| table_list(xndx); -- dbms_output.put_line(v_sqltext); BEGIN execute immediate v_sqltext into v_count; dbms_output.put_line(table_list(xndx) || ', ' || v_count); exception when OTHERS then dbms_output.put_line(table_list(xndx) || ', NULL'); END; end if; end loop; end; / This is my version w/o the cool XML stuff that Laurent has.

if table_list.exists(xndx)
and table_list(xndx) not like ‘SYS.%’ then

A disadvantage of both is that the performance will degrade due to DOM validation, BUT... GREAT EXAMPLE Laurent. I love it!

What I meant was that no cursor is necessary: create or replace function count_rows(table_name varchar2) return varchar2 is i number; begin execute immediate 'select count(*) c from '||table_name into i; return i; end; / select count_rows(table_name) from user_tables; Opps, your function is scalar which is simpler than table function.
