[Oracle] TABLE, INDEX 실 데이터 size 구하기

TABLE size 구하기
set pagesize 9999
col owner format a10
col tablespace_name format a20
col table_name format a30
col mb format 99990.99

SELECT OWNER, TABLESPACE_NAME, TABLE_NAME, NUM_ROWS*AVG_ROW_LEN/1024/1024 as MB
FROM DBA_TABLES
WHERE OWNER IN ('ADPORTAL','INTRADBA','UWDBA','WEBSALES')
ORDER BY OWNER, TABLESPACE_NAME, TABLE_NAME;

INDEX size 구하기
db_block_size를 LEAF_BLOCKS과 곱한다
select value from v$parameter where name = 'db_block_size'

set pagesize 9999
col owner format a10
col tablespace_name format a20
col index_name format a30
col mb format 99990.99
