使用主变量或实际文本时，DB 2不会对非索引考虑这个因素；只有您能够考虑这个因素并相应编码。
With host variables or literals, DB2 does not consider this factor for non-index predicates; only you can take this fact into account and code accordingly.
您还研究了参数标记/主变量的使用会为DB2优化器对分布统计信息的考虑带来怎样的限制。
You have also examined how the use of parameter markers/host variables may limit the consideration of distribution statistics by the DB2 optimizer.
最后，输出使用从主规则的单词和ID创建的变量。
Finally, the output USES variables created from the words and the IDs of the master rules.
然后，主脚本只需导入这个config .py并直接使用那些变量即可。
The main script can then just import the config.py and use those variables directly.
为了提高模型的预测准确率，使用了双变量统计和主成份对数据进行预处理和分析。
To improve the forecasting accuracy, bivariate statistics and PCA were used to prepare and analyze the data in advance.
