好多的date列，各种不同的格式。还是需要对每个date列分别定义缺省格式，才会比较好用。
现在好多人回避使用date类型，就是嫌其不方便。
这么多列的表，还可能会增加一些列。
写这个语句，绑定那么多变量，人会疯掉的啊。。。。。
幸亏，这不是我写的，是程序自动生成的。变量是自动绑定的。。。OCI包装器。。。类似的表还有好几个，由一个程序处理的，柔性编程，或者说数据库泛型编程，纯C的，谁说C不能泛型？典型的sqlldr，我也能。
5 RC_MID:7F5B69AD4700 09/25 13:09'54 array_ins_DAO:tabname=CUT_PI_EXIT,rec_num=1000,ret=1000,err=0,,TM=146911同一个函数（array_ins_DAO）处理的另一张表。这个泛型技术，不同于STL，它那个是编译时泛型，就是在编译期必须知道数据类型，而这个是运行时泛型，编译时你并不知道具体的数据类型，执行时才知道。
好处，一个函数可以处理多个表。表结构改变时程序无需修改。
语句不会写错。
