selecting digits using proc sql

Nehcour0420 — Wed, 01 Aug 2012 14:07:10 GMT

Hi,

In IBM DB2, we can select certain digits from left or right, I am wondering if I can use proc sql to achieve same functionality as:

RIGHT(DIGITS(test.Id_Number), 3)

Thanks,

Eric

how about:

data have;
input v $;
cards;
adf124a
3456pb
7g39b2
;

proc sql;
select substr(compress(v,,'kd'),length(compress(v,,'kd'))-2)as new
from have;
quit;

Thanks Linlin,

If I understand right, the sub string is a char type and could not be used to compared with a numeric type, is that right?

Yes,it is a character variable. you can convert it to numeric:

data have;
input v $;
cards;
adf124a
3456pb
7g39b2
;

proc sql;
create table want as select input(substr(compress(v,,'kd'),length(compress(v,,'kd'))-2),3.) as new
from have;
quit;
proc contents data=want;run;
