With the SAS macro facility, a many-to-many merge can be done within the program, without checkingthe number of times an observation appears in the data andwithout needing to change the code with each new data setrevision. Programmers with a basic understanding of datamanipulation and merging ...
如果SAS发现至少存在一组BY变量的值在两个数据集中均不能唯一的确定一条记录,这时才算做真正的many to many match merge.如果情况是对于一组BY变量的值在左边的数据集中不能唯一的确定一条记录,但是在右边的数据中能唯一的确定一条记录,而对于另一组BY变量的值恰好反过来。这实际上只能算作2)。所以确切地讲,你...
Once we have the crosswalk, we can use a nested join in Proc sql to create an SQL View. But sometimes we want a data view that utilizes features of the SAS; Data step that cannot be easily duplicated in Proc sql. We can perform this merge in a Data step with the hash object. ...
