The algorithm integrates the linear indexing technique and flag map which LZC adopts, USES the scan order which is the same of SPIHT algorithm, sends the coding stream into MQ in code process.
该算法引入了线性索引技术和LZC算法标志位图,采用了类似于SPIHT算法的扫描顺序,将待编码流按不同种类进行算术编码。
For the merge scan join to perform properly, both inputs are expected to be in the order of join columns.
为了合并扫描联接正确地执行,按照联接列的顺序预计有两个输入。
As shown in the IXSCAN descriptor in Figure 8, the leading column of the index exploited by optimizer is PRODUCT_NUMBER, which does not provide the order required for merge scan join.
如图8的IXSCAN描述符所示,通过优化器利用的索引的领先列是PRODUCT _ NUMBER,其不为合并扫描联接提供所需的顺序。
