[軟體熟悉度]:
新手(不到1個月)
[問題敘述]:
大家好
我想要合併兩個EXCEL檔案
這兩個檔案都有date lacation grade 三個項目
其中aa有sales
bb則是price
我有辦法利用那三個共同的項目去篩選出同一天 同一地點 同個grade
的sales跟price嗎
比如說
aa檔是
Location Date Grade Sales
118 7/15 Diesel 2000.00
113 7/15 Premium 100.00
9 7/15 Diesel 300.00
6 7/16 Premium 105.00
bb檔是
Location Date Grade Price
113 7/15 Premium 2.50
118 7/15 Diesel 2.78
6 7/16 Premium 2.61
12 7/16 Unleaded 2.30
然後我要的結果大概是
Location Date Grade Sales Price
118 7/15 Diesel 2000.00 2.78
113 7/15 Premium 100.00 2.50
9 7/15 Diesel 300.00 N/A
6 7/16 Premium 105.00 2.61
12 7/16 Unleaded N/A 2.30
因為兩個檔案都約有20000多筆資料 分別有缺漏
我用了merge也沒辦法
想知道SAS有沒有這種code能辦到
[程式範例]:
我現在是用這樣
proc import datafile="C:\Users\user\Desktop\FBS.csv" out=aa;
run;
proc import datafile="C:\Users\user\Desktop\FB.csv" out=bb;
run;
proc sort data=aa;
by Date ;
run;
proc sort data=bb;
by Date;
run;
data cc;
merge bb aa(rename=(Grade=gra1 Location=loct1));
by Date Location;
proc print;
run
但是因為資料量不同好像根本無法這樣merge
請問有高手知道該怎麼辦嗎
謝謝
