Re: Space released during Orcale DB reorg..??

Hi All, I went through SAP note 821687 I ran the below query and got the wasted space of the top 20 tables. I have never worked or reorg but believe if I do a reorg of these tables I can reclaim the wasted space.

"SELECT * FROM (SELECT     SUBSTR(TABLE_NAME, 1, 21) TABLE_NAME,     NUM_ROWS,     AVG_ROW_LEN ROWLEN,     BLOCKS,     ROUND((AVG_ROW_LEN + 1) * NUM_ROWS / 1000000, 0) NET_MB,     ROUND(BLOCKS * (8000 - 23 * INI_TRANS) *       (1 - PCT_FREE / 100) / 1000000, 0) GROSS_MB,     ROUND((BLOCKS * (8000 - 23 * INI_TRANS) * (1 - PCT_FREE / 100) -       (AVG_ROW_LEN + 1) * NUM_ROWS) / 1000000) "WASTED_MB"   FROM DBA_TABLES   WHERE     NUM_ROWS IS NOT NULL AND     OWNER LIKE 'SAP%' AND     PARTITIONED = 'NO' AND     (IOT_TYPE != 'IOT' OR IOT_TYPE IS NULL)   ORDER BY 7 DESC) WHERE ROWNUM <=20;"

Can this wasted space be reclaimed after the reorg..??

Thanks in advance.
