Question

SELECT 'analyze table '||table_name||' compute statistics for table;'
from user_tables;
SELECT table_name,num_rows
FROM user_tables; Hi I am getting null NUM_ROWS column what could be the reason and how can I fix it?

Answer 1

It works ... for me however.....!!!!
SQL> create table f(b varchar2(10) , g number(2));
Table created
SQL> insert into f values('5',4);
1 row inserted
SQL> insert into f values('e',4);
1 row inserted
SQL> commit;
Commit complete
SQL> select table_name,num_rows from user_tables where table_name='F';
TABLE_NAME                       NUM_ROWS
F                             
SQL>
SQL> begin
  2   for r in ( select table_name from user_tables )
  3   loop
  4   execute immediate 'analyze table '||r.table_name||' compute statistics for table';
  5   end loop;
  6   end;
  7  /
PL/SQL procedure successfully completed
SQL> select table_name,num_rows from user_tables where table_name='F';
TABLE_NAME                       NUM_ROWS
F                                       2
If you repeat the above simple test don't you get the same results.....????
