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4KB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.
将输出记录填充到固定长度。
此示例演示了如何将ParsedRecordSequence记录检测用于MRMCWF解析器,以通过消息流传播固定长度的单独记录。
This example demonstrates how a record Detection of Parsed record Sequence can be used with the MRM CWF parser, to propagate separate fixed length records through a message flow.
要把数据表中的相似重复记录标识出来,常用的方法是先将所有记录按照某个关键字进行索引,然后在一个固定长度的窗口范围内进行记录的两两比对。
The common approach of marking the approximately duplicate records is that a pair of records are compared in a window with fixed length after these records are indexed by a certain keyword.
