下面来看看执行到这一步生成的_tem_spec数据集。 上面的那个段data step目的就是生成截图中被框起来的部分,是不是很眼熟,这个Proc Sql中的语法结构,然后将其赋值宏变量,丢到Proc Sql过程步中,就实现了变量的自动抓取。基于数据的多变性,目前这里小编就设置了一种抓取(单数据集直接获取变量无加工),如果涉及到了...

数据步骤合并过程:数据步骤合并过程是通过数据步骤(DATA Step)来实现数据合并的过程。在SAS中,可以使用DATA Step语句来执行数据步骤合并操作。数据步骤合并过程可以根据一个或多个共同的变量将两个或多个数据集合并成一个新的数据集。常用的数据步骤合并操作包括合并、追加和更新。 合并(MERGE):将两个数据集中的记录按...
