发帖数: 1504 | 2 我用SQL是这样搞的：
proc sql;
create table WANT as
select distinct a.*, b.VAR1 , b.VAR2
from HAVE1 as a left join HAVE2 (DROP=link_count) as b
on a.PATIENT_ID = b.PATIENT_ID and a.YEAR = b.YEAR;
quit;
但是应为硬盘容量有限，所以只能用DATA STEP了。请问出来的WANTtable是不是一模一
样的啊？
proc sort data=HAVE1;
by PATIENT_ID YEAR;
run;
proc sort data=HAVE2(keep=PATIENT_ID YEAR VAR1 VAR2);
by PATIENT_ID YEAR;
run;
data WANT;
merge HAVE1 (in=a) HAVE2(in=b);
by PATIENT_ID YEAR;
if a;
run; |

发帖数: 1504 | 3 非常简单的程序，run了一个下午都没run出来。
Both have1 and have2 have few variables, but many observations.
proc sql;
create table want as
select *
from have1 as a left have2 as b
on b.serie_beg <= a.serie <= b.serie_end;
quit;
把上面left join换成inner join也一样。。。
serie_beg, serie, and serie_end都是上billion的数值（numeric）。请怎么会这么
久啊？ |

发帖数: 1504 | 4 真不好意思啊。你说的有重名，请问可以举一个例子吗？
假设Have1 有下面几个variable （400 GB的那个）
hospital_visit_id, date, time, patient_id, document_id
Have2有下面几个variable （800 MB的那个）
patient_id, document_id, diag_date, diag_type
应该就没有问题吧？
如果另外我把前面条件改动，让HAVE1和HAVE2都有一个共同的variable叫comomon_
variable，这种情况就会出现你提到的改动问题吧？谢谢！ |

发帖数: 102 | 5 你这种情况是该用hash，假设have2是800M.
data merged;
length var1 var2 $8.;*这里要根据实际情况改，但必须定义var1 var2；
if _n_=1 then do;
dcl hash h(dataset:"have2");
h.definekey("PATIENT_ID","YEAR");
h.definedata("VAR1","VAR2");
h.definedone();
call missing(var1,var2);
end;
set have1;
if h.find() ne 0 then call missing(var1,var2);
run; |

发帖数: 7 | 8 Hi,
I'm J1-visa and will work in China two years, however, I plan to be
back United States, I just want to know how to calculate 2 years and avoid
some troubles. How to prove I already have2 years period in China, from

send to the U.S. immigration. example, I leave United States: 07/20/2012,
then I get F1-student visa 05/10/2014, and enter the United States at 08/05/
2014 (I-94).
The two years would be from 0... 阅读全帖 |
