通过shell检查分区表中是否含有默认分区

sqlplus -s $1/$2@$SH_DB_SID set head off
set pages 100
set linesize 200
/* bad performance

from user_tab_partitions where  partition_name like '%MAX%'
  )
)
group by name;
*/
select 'alter table  '||table_name||' add partition  PMAXVALUE  values less than ('||

exit

 简单运行一下，可以看到有一些分区表是灭有默认的分区的。可以根据自己的情况来定夺。
