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.....

With that method, it would be causing more and more tablespace fragments, and make the performance decresing.

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.

adv. 在那里；到那里；从那里。

pron. 表示存在（与be连用）。

n. 那个地方；那一点。

there

读音：英 [ðeə(r)]、美 [ðer]

语法：

1、there用作副词主要表示空间位置“那里”，与静态动词连用时意为“在那里”，与动态动词连用时意为“往那里”。there用作定语时只可后置。

2、用there开头的感叹句加强语气时，谓语动词通常不用现在进行时态，而用一般现在时态，如果主语是名词或名词短语，句子须倒装; 若主语是人称代词，句子不可倒装。
