即使目前对于多数公司而言,compare 过程很可能是在一个很大的macro工具中,但了解一下compare过程步的内容仍然是很有帮助的。请注意,本文不会详细解释所需SAS code细节,如对其中选项或语句有不熟悉的或者想要进一步了解的话,可以访问SAS help Center自行搜索https://documentation.sas.com/doc/en/helpcenterwlcm/1.0/ho...
SAS(R) PROC COMPARE is a valuable tool to use for comparing specific variables within a single data set, allvariables across two different data sets, or specific variables across two different data sets. For example, whenworking with new functions for the first time, you may want to verify ...

在SAS base 中,PROC COMPARE 可以比较两个数据集的差异,实际工作中常应用在 ADaM 和 TFL 的 QC 中,下面介绍一些 PROC COMPARE 常用的使用技巧。 指定主键 默认情况下,PROC COMPARE 从第一个观测开始,逐行对比两个数据集的观测。在数据集没有增减观测的情况下,这样做一般没有问题。如果两个数据在观测数量上存在...
系统宏变量回返回过程步的结果,有的时候非常有用。比如我们需要做一个宏工具,来扫描指定的两个逻辑库下,所有同名数据集是否相同。 这个时候我们需要程序自动读取过程步proc compare的信息。如果没有sysinfo,那么我们可能需要通过导出数据集,然后对比数据集得出结论。但是sysinfo这个宏变量可以让我们直接获取需要的信息。
