SAS質問をレコード生成したい：私は名前の列を有するテーブルがあります。以下に示すようにPrimary_coverage 4観測を有する、

私は私のテーブル値を下図のように見える必要がありますように、動的に年、四半期、月、列値をループするマクロを作成するとします（2000Q1 2002Q4へ= 36ヶ月、12四半期、3年） 注：最も早い年は常に2000Q1から始まります

Answer 1

日付の組み合わせを使用しますこれを達成するための機能。 INTNXを使用して日付を増減し、YYYYQQをSAS日付に変換するにはinput（）を使用します。

Doループは簡単です。

%let end_date = 2003Q2; 

data date_list; 
    format end_date date9. coverage $20.; 
    end_date=input("&end_date", yyq6.); 
    n_months=intck('month', '01Jan2000'd, end_date)+3; 



    do coverage='Primary', 'Secondary', 'Tertiary'; 
    date=end_date; 
     do months=n_months to 3 by -3; 
      year=year(date); 
      quarter=qtr(date); 
      date=intnx('month', date, -3, 'b'); 
      output; 
     end; 
    end; 
    Keep year quarter months coverage; 
run;
