There is a project that need collecting periodically (2 months) data into one table and then exporting it as excel file. The table is a temporary table, the app do that

delete from tb_name;

insert into tb_name values.....
...
insert into tb_name values.....

In other to avoid this disadvantage influences, I suggest programer modify the app as

truncate table tb_name drop storage;

insert into tb_name select * from ...

The delete operation will be causing tablespace fragments.
