DB2 UDB does not allow MAXVALUE to be followed by any other values, and the range must be valid for each partition value.
DB 2UD B不允许MAXVALUE后面跟上任何其他值,每个分区值的范围必须有效。
RANGE/TABLE PARTITIONING (Available with DB2 9) - splitting data by key range over multiple physical objects within a logical database partition.
RANGE/TABLEPARTITIONING(DB29提供) ——根据键范围将数据划分到一个逻辑数据库分区中的多个物理对象上。
Data is partitioned by node, so these queries can each be answered by a single partition, using an indexed range query.
数据根据节点分块,所以这些查询能分别在各自的数据块,通过一个索引过的范围查询得到结果。
The results for any arbitrary range is the sum of all the partitions fully enclosed by the range plus the results of linear scans for any fragments that are not aligned on your partition boundaries.
任意范围的结果是所有的分区全封闭的范围内加任何片段是未对齐的分区边界的线性扫描结果的总和。
Experimental results shows that obtaining threshold by image partition and restricting the range of the modulus can accomplish better edge detect results.
实验结果表明,采用图像分块方法确定阈值,并用该阈值来限定模值,可以得到更好的边缘检测效果。
