I am merging two data sets. My report data has company, line, zip and 8 numerical variables (107 obs). The zip in report data is only a partial list for a given state. The template data set has all the zips for that state (1071 obs). The desired result after merging the two data sets "by zip" is the report data with company, line and 8 numerical variables and all zips in the template data set with company and line appearing on each observation with zeros in numeric variables (1071 obs).
When I merge, I am getting blank company, line for data not in template.
Help please!
Please post example data. Use the macro from https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat... to create datasteps from your datasets, and post those in a code window (6th {i} or 7th "little running man" icons above the posting window, see https://communities.sas.com/t5/help/faqpage/faq-category-id/posting).
Also post your code.
Here's a quick code example:
data have;
input company $ zip $ var1 var2;
cards;
A 123456 1 1
B 123457 2 2
;
run;
data zips;
input zip $;
cards;
123456
123457
123458
;
run;
data want;
merge
have (in=_have)
zips (in=_zip)
;
by zip;
if not _have
then do;
var1 = 0;
var2 = 0;
end;
run;
proc print data=want noobs;
run;
Result:
company zip var1 var2 A 123456 1 1 B 123457 2 2 123458 0 0
After reading your initial post again, I think you want a cartesian product with all the zips?
In this case it is an issue for proc sql:
proc sql;
create table want as
select
a.company,
b.zip as zip,
case when b.zip = a.zip
then var1
else 0
end as var1,
case when b.zip = a.zip
then var2
else 0
end as var2
from have a, zips b
order by company, zip
;
quit;
(using my example data from the other post)
