PROC SQL：如何将多个查询放在一个查询中，以便并排解决方案？

Question

我有三个问题。 1) 计数 * 个记录 table 2) 计算匹配的记录或仅因原因 1 而未使用的记录 3) 计算匹配的但仅因原因 2 而未使用的记录

如何将 3 个查询合二为一并同时将查询 2 和 3 添加到一起，这样我就不必有两到三个列。所以在 excel 中看起来像：[1]: http://imgur.com/IQp82sx

 /* 1 */ /* This finds amount of records */
    proc sql; 
    create table
      work.Original_count
    as 
    select
        count(*) as occurences
    from 
        WORK.query_for_reports1 as t1;
    quit;

    /* 2 *//* counts how many records are already matched  in technique ED*/ /* 10 */ 
    proc sql; 
    create table
         work.occ_matched_T1
    as 
    select
        count(*) as occurences 
    from 
       work.QUERY_FOR_REPORTS1 as t1 
    where t1.EdSYS is not null;
    quit;

    /*3 */ /* Counts how many records are already matched with IP */ /* 9 */
    proc sql; 
    create table 
        work.occ_matched_t1_1
    as 
    select 
           count(*) as occurences 
    from 
        work.E_DATA_UNMATCHED as t1
    where t1.Ip is not null;

quit;

Answer 1

proc sql;
create table wanted as
select t1.occurences as original_count
      ,t2.occurences as matched_by_T1
      ,t3.occurences as matched_by_T2
      ,t2.occurences+t3.occurences as B2_C2
from (select count(*) as occurences from query_for_reports1) t1
    ,(select count(*) as occurences from query_for_reports1 where edsys is not null) t2
    ,(select count(*) as occurences from e_data_unmatched where ip is not null) t3
;
quit;
