为什么不好呢，发现那个num设成10000，就会很慢 ，原因是首先的拼接，需要一点时间，这个还好，关键是删除的次数会增加很多次，这种代码放到项目上，完了绝对算得上是漏洞了。

有时候在查询或者进行其他处理的时候，需要把字符串尾部的空格字符去掉。如有时候应用软件设计的不合理，会把空格字符保存在数据库中。如在输入产品品号的时候，用户不小心，把“DT001”输成了“DT001”。如果应用程序在设计的时候，能够自动把尾部的空格去掉然后在保存到数据库中能够就万无一失了。但是不少的应用软件在开发的时候没有如此设计。这就给后续的处理带来了很多的麻烦。因为利用Where语句来查找记录的时候，“DT001”(最后不带空格)与“DT001”(最后带一]]>
