Describe a time when you were really stuck on a problem and
how you solved it?
There is a field containing a date. It needs to be
displayed in the format “ddmonyy” if it’s before
1975,”dd
mon ccyy” if it’s after 1985, and as ‘disco years’ if
its
between 1975 and 1985. How would you accomplish this in
data step code? Using only PROC FORMAT.
data data1;
input dt account;
format dt date9.;
cards;
1745 1230
1756 1120
1788 1130
1767 1240
;
data data2;
input startdt enddt total;
format startdt date9. enddt date9.;
cards;
1657 1834 12300
1557 1758 16800
1789 1789 12300
1788 1345 12383
1899 1899 13250
;
proc sql;
create table data3 as
select * from data1 as x left join data2 as y
on x.dt>=y.startdt and x.dt<=y.enddt;
quit;
Here, we are getting cartision product. But,I want left
join report consisting of this program. It should not get
duplicate values. you can modify the program also.
