Hello. My_SAS.
Sorry ! I understood what you mean now.
Data Test; input id no sdate : ddmmyy10. Endate : ddmmyy10.; Format sdate Endate ddmmyy10.; cards; 1 10 13/01/2011 . 2 11 13/01/2011 . 3 12 13/01/2011 . 4 13 13/01/2011 . ; run; data inc; input id no; cards; 1 14 2 15 3 12 4 13 ; run; proc sql; create table temp as select * from inc except select * from test(keep=id no) ; quit; data test; if _n_ eq 1 then do; length id 8; declare hash h(dataset:'temp'); h.definekey('id'); h.definedone(); end; set test; if h.check()=0 then Endate="&sysdate"d; run; data temp; set temp; sdate="&sysdate"d; run; proc append base=test data=temp force nowarn;run;

How about:
Data Test; input id no; cards; 1 10 2 11 3 12 4 13 ; run; data inc; input id no; cards; 1 14 2 15 3 12 4 13 ; run; proc sql; create table want as select * from test union all corresponding (select * from inc except select * from test) ; quit;

Thqs Ksharp small Modification can you help me in this
Data Test;
input id no sdate ddmmyy10. Endate ddmmyy10.;
Format sdate Endate ddmmyy10.;
cards;
1 10 13/01/2011 .
2 11 13/01/2011 .
3 12 13/01/2011 .
4 13 13/01/2011 .
;
run;
data inc;
input id no;
cards;
1 14
2 15
3 12
4 13
;
run;
For the Inc Table the Sdate and Edate will be sysdate (Today Date)
Output Test:
ID No sdate Edate
1 10 13/01/2012 17/01/2012
2 11 13/01/2012 17/01/2012
3 12 13/01/2012 .
4 13 13/01/2012 .
1 14 17/01/2012
2 15 17/01/2012
OK.
Data Test; input id no sdate : ddmmyy10. Endate : ddmmyy10.; Format sdate Endate ddmmyy10.; cards; 1 10 13/01/2011 . 2 11 13/01/2011 . 3 12 13/01/2011 . 4 13 13/01/2011 . ; run; data inc; input id no; cards; 1 14 2 15 3 12 4 13 ; run; proc sql; create table temp as select * from inc except select * from test(keep=id no) ; quit; data test; set test; if _n_ le 2 then Endate="&sysdate"d; run; data temp; set temp; sdate="&sysdate"d; run; proc append base=test data=temp force nowarn;run;
Ksharp
But you have kept
data test;
set test;
if _n_ le 2 then Endate="&sysdate"d;
run;
As i know only two observations have changed you have kept _n_ le 2 if the count increase how can i handle them
You want all the value of Endate to be SYSDATE?
Then remove the condition.
data test;
set test;
Endate="&sysdate"d;
run;
data temp;
set temp;
sdate="&sysdate"d;
Endate="&sysdate"d;
run;
Ksharp
I want the output like this
Output Test:
ID No sdate Edate
1 10 13/01/2012 17/01/2012
2 11 13/01/2012 17/01/2012
3 12 13/01/2012 .
4 13 13/01/2012 .
1 14 17/01/2012
2 15 17/01/2012
But in the code at one poing you have written
if _n_ le 2 then Endate="&sysdate"d;
as i am having 2 obs i know and can keep _n_ le 2 if the count increae how can i do
You can change it as you wish.
if _n_ le 4
Or You want to pick up a proportional obs?

Thqs it worked ,is there any way to do this with out Hash keys
I didn't read your specs fully, but the following produces the same result as long as both of your input files (i.e., test and inc) are in id order:
data test (drop=b_:);
merge test (in=ina) inc (in=inb rename=(no=b_no));
by id;
if ina and inb then do;
if no ne b_no then do;
Endate=today();
output;
call missing(Endate);
sdate=today();
no=b_no;
output;
end;
else output;
end;
else if ina then output;
run;
proc sort data=test;
by no;
run;
OK. Here is a pure SQL method. If you like it.
Data Test; input id no sdate : ddmmyy10. Endate : ddmmyy10.; Format sdate Endate ddmmyy10.; cards; 1 10 13/01/2011 . 2 11 13/01/2011 . 3 12 13/01/2011 . 4 13 13/01/2011 . ; run; data inc; input id no; cards; 1 14 2 15 3 12 4 13 ; run; proc sql; create table temp as select * from inc except select * from test(keep=id no) ; create table want as select a.id,a.no,sdate,case when missing(b.id) then . else "&sysdate"d end as Endate format=ddmmyy10. from test as a left join temp as b on a.id = b.id outer union corresponding select *,"&sysdate"d as sdate from temp ; quit;
