Misc

dbms_stats uses sys.col_usage$ to decide if it is worth building a histogram on a column.

Examples

The following script finds out, how many rows in a table are stored. The tablenames of the tables are stored in info_tablerows.
create table t1 (a number);

begin
  for i in 100 .. 110 loop
    insert into t1 values (i);
  end loop;
end;
/

create table t2 (a number);

begin
  for i in 1000 .. 1100 loop
    insert into t2 values (i);
  end loop;
end;
/

create table t3 (a number);
begin
  for i in 2000 .. 2200 loop
    insert into t3 values (i);
  end loop;
end;
/

commit;


create table info_tablerows (
  tablename varchar2(30) primary key
);

insert into info_tablerows values ('t1');
insert into info_tablerows values ('t2');
insert into info_tablerows values ('t3');

commit;

declare
  cursor c is select tablename from info_tablerows;
begin
  for r in c loop
    dbms_output.put_line(r.tablename);
    dbms_stats.gather_table_stats(user,r.tablename);
  end loop;
end;
/

create view v_num_rows as 
  select num_rows, table_name from 
  user_tables u, info_tablerows i where
  u.table_name = upper(i.tablename);

select * from v_num_rows;

drop table t1;
drop table t2;
drop table t3;
drop table info_tablerows;
drop view v_num_rows;

Misc Stuff

Collecting statistics does not invalidate cursors (at least on some versions). So, a alter system flush shared pool should be issued after collecting the stats so that a hard parse is forced when a cursor is opened anew.
