要想统计用户下所有表的数据量，可以查看user_tables，此表里面是统计信息，当然这个可能不太准，要想非常精确，需要直接count表。下面的脚本有异常不中断，可以重复执行的特点。
create table bk_count_tables( owner VARCHAR2(30), table_name VARCHAR2(30), part_col varchar2(100),--分区字段 row_s number, gather_time date);
create index ind_bct_own_table on bk_count_tables(owner,table_name);
set serveroutput ondeclarecursor c_cursor is select s.OWNER, s.TABLE_NAME, col.column_name part_col from dba_tables s, (select owner, name, listagg(column_name, ',') within group(order by null) column_name from (select owner, name, column_name from dba_part_key_columns where owner in ('TEST') and object_type = 'TABLE' and name not like 'BIN$%' union all select owner, name, column_name from dba_subpart_key_columns where owner in ('TEST') and object_type = 'TABLE' and name not like 'BIN$%') group by owner, name) col where s.OWNER in ('TEST') and not regexp_like(table_name, '[0-9]{
3,8}
') and s.table_name not like '%BAK%' and s.table_name not like '%A2K%' and s.table_name not like 'BK%' and s.table_name not like 'BIN%' and s.OWNER = col.owner(+) and s.TABLE_NAME = col.name(+)order by s.TABLE_NAME ;
c_row c_cursor%rowtype;
t_rows number;
begin for c_row in c_cursor loop begin execute immediate 'select count(*) from bk_count_tables where owner=:1 and TABLE_NAME=:2 and rownum=1' into t_rows using c_row.OWNER,c_row.TABLE_NAME ;
if(t_rows = 0) then execute immediate 'select count(*) from "'||c_row.TABLE_NAME||'"' into t_rows;
insert into bk_count_tables values(c_row.OWNER,c_row.TABLE_NAME,c_row.part_col,t_rows,sysdate);
commit;
end if;
EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE(c_row.OWNER||'---'||c_row.TABLE_NAME);
rollback;
end;
end loop;
end;
/
