The -c option creates the lookup tables declared with the const keyword; the contents of all generated lookup tables then are constant-that is, read-only.

When lookup tables are used in joins with other large partitioned table spaces, you can maximize the parallelism in the join by partitioning the lookup tables as well.
当将查找(lookup)表与其他较大的分区的表相连接时,通过将查找表也进行分区,可以最大化并行度。
In addition to using lookup tables to extract additional metadata, other techniques can be used to make the form consistent with other user interface development standards.
除了使用查询表提取额外元数据之外,还可以使用其他技术让表单与其他用户界面开发标准保持一致。
This is a major advantage for lookup tables: since there are no conditions to evaluate, there is little or no additional overhead as the number of possible values increases.
使用查表法的一个主要优点是:由于没有条件判断,当候选值数量增加时,很少,甚至没有增加额外的性能开销。
With side tables, DB2 first performs an index lookup on the side table and then joins the corresponding row with the main table that contains the CLOBs.
在使用索引表的情况下,DB 2首先对索引表执行索引查找,然后将对应的行和包含CLOB的主表相结合。
The resulting code for handling all aspects of this lookup was straightforward but rather unwieldy, especially if you happen to have multiple tables that you want to use throughout a transform.
处理这类查找的代码非常简单但是相当笨拙,尤其是在转换中使用多个表的时候。
The transformer carries out a lookup action in non-primary tables for records of the primary table.
