oracle数字开头表空间创建及含lob字段表统计

1、创建时加上双引号create tablespace "320DB" datafile '/u01/app/oracle/oradata/orcltwo/data01.dbf' size 30G;alter tablespace "320DB" add datafile '/u01/app/oracle/oradata/orcltwo/data02.dbf' size 30G

3、统计大数据segmentselect * from ( select sum(bytes)/1024/1024/1024 sizem,segment_name,segment_type from dba_segments where owner='SA' --and segment_type like 'TABLE%' group by segment_name,segment_type ) a where a.sizem > 1统计大于1G的所有segment注意：索引、表、lob都属于segment

5、统计某用户所有含lob字段的表select distinct table_name from dba_lobs where owner='SA'
