SELECT
 tb.owner towner

, tb.table_name tname
, tb.num_rows row_cnt
, sg.extents ext
, sg.blocks Blk
, tb.blocks b_Blk
, tb.empty_blocks a_Blk
, ( sg.blocks - tb.blocks -  tb.empty_blocks ) Ovr
, (sg.blocks - tb.empty_blocks - 1) hwm_Blk

FROM sys.dba_tables tb, sys.dba_segments sg WHERE tb.table_name = sg.segment_name
