→ ASD332:set + set point 可以喔! 11/15 18:25

想請問一下SAS中SQL和MERGE合併的產出結果
假設有兩個原始DATASET:A、B
Dataset A Dataset B
Common Column_A Common Column_B
M 1 M 1
M 2 M 2
我想用MERGE PROCESS合併成以下結果:
Common Column_A Column_B
M 1 1
M 1 2
M 2 1
M 2 2
The merge process is as following, but fail to meet my requirement.
Data merge_A_B;
merge a b;
by common;
run;
但似乎都會變成
Common Column_A Column_B
M 1 1
M 2 2
-------------------
以SQL寫的話 產出會符合我的需求
但有辦法用MERGE PROCESS寫嗎??(因為一些緣故 必須用MERGE寫)
