Maiores tabelas e atualização de estatísticas

Verificando as maiores tabelas e a atualização de estatísticas das tabelas.

select table_name, round((num_rows*avg_row_len)/1048576) tbsize, num_rows, last_analyzed
from all_tables
where owner='MAX'
and num_rows>0
order by num_rows desc

resultado

table_name   tbsize   num_rows    last_analyzed
WOSTATUS     27442    306121780   24-SET-21
WORKORDER    65996    95582941    24-SET-21
...

Mesmo que seu ambiente tenha pouca movimentação, atualizar as estatísticas é fundamental pra um funcionamento do ambiente com qualidade.

Atualização de estatísticas

from all_tables
where owner='MAX'
and num_rows>0
group by TO_CHAR(last_analyzed)
order by TO_CHAR(last_analyzed)
