还有一些情况下,对于一条固定长度的记录,其总长度可能刚好比4 KB的一半大一点点,这时一个页只能容纳一条记录。
In other situations the total length of a fixed record may be just slightly longer than one-half a 4 KB page, so then only one record can fit on a page.
如果记录是固定长度的,那么就无需将其从存储它的初始页面转移到其他地方。
If a record is fixed length, it never needs to be moved from the page on which it is originally stored.
固定长度的记录要优于可变长度的记录,因为 DB2 代码专门为处理固定长度的记录进行优化。
Fixed-length records are preferred over varying length records, because the DB2 code is optimized for processing fixed-length records.
