Trying to make a table comparing school quality to zip code (using proc freq)

The school quality is measured by the numeric variable Stars (1-5) & the zip code is the basic 5 digit zip. However, since the 5-digit zips are too narrow, I want to use the first 3 numbers of the zip codes for a broader comparison

I'm at a loss for how to read in the 5-digit zip code but then chop it to 3-digits for this table (want it to stay 5 digits everywhere else)

Suggestions?

something like
ZipArea=(ZipCode-(ZipCode%100))/100

[Edited on February 24, 2011 at 7:50 PM. Reason : or if there is an integer type with no implicit casting of integer division, ZA=ZC/100

I think you can use the substring function.
New_zip = substr(zip,1,3);
That basically says take the first 3 characters of the original variable and create a new variable called new_zip.

This will work as long as you define zipcode as a character variable, not numeric.

data zips;
input zip5 $;
zip3=substr(zip5,1,3);
cards;
12345
23456
34567
;

run;

proc print data=zips;
run;

You wanna use substrn, but it can be a numeric.

data zipset;
set zipset;
zip3=substrn(zip5,1,3);
drop zip5;
RUN;

put(zip, 3.); would also have been my answer to this question

You might consider creating a web service to handle this, since the functionality is so controversial, that way the implementation is abstracted away and you can write it in a language you're more comfortable in.

As long as you have a well-formed WSDL file for the web service, SAS 9 has some powerful web service procedures that you can use to implement calls.

sweet.

So how long should a proc tabulate summary table take with ~4.5mil records?

I'm trying to make a pivot table basically but it has been running about an hour. Running on 1 core at 2.53 GHz, right now at about 500MB/12GB ram.

If it's never going to finish I'll go ahead and kill it but I don't have any idea how long it should take.

I would've guessed 3 minutes. Try it with a smaller table. You can do something like "proc tabulate data=something(obs=1000)"

I can usually do 300 mil records in an hour

I just went back to Access and did a crosstab query. I must have set something up wrong in SAS b/c it froze up after about 4 hours, whereas its only 10 min from import in Access to export in Excel.

^thanks

coming back to this thread with a little more experience but probably just as idiotic of a question.

have a macro that creates a bunch of speed datatables with a datetime and speed column. I want to create an index time table with all possible datetimes between the first and last in the entire dataset so I can merge all the tables together and have rows of blank speeds when none of the speed tables report a speed.

tl;dr: given a start and end datetime and an interval in minutes, I need a table with all times between in a single column.

here's what I've got so far:

proc sql noprint;
select min(time)
into :mintime
from inrix;

proc sql noprint;
select max(time)
into :maxtime
from inrix;

%let obs=%eval(

proc sql noprint;
create table timeindex
(time date format=datetime.);

%let timer=&mintime;

%do %while(&timer<=&maxtime);

proc sql noprint;
insert into timeindex
set time=&timer;

%let timer=%eval(&timer+%eval(&interval*60));

%end;



It seems to work when I put an integer in for mintime and maxtime in a test macro (extremely slowly), but says

Quote :
"A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The condition was: 1.6356E9+60"



when run within the whole macro. I'm guessing the first two proc sql statements are formatting the variables into dates, but I don't know how to fix that. Plus, the condition quoted looks like two numbers to me.

Looks like I was definitely getting ahead of myself attempting awesome macros and sql inserts


This:

data timeindex;
do time=&mintime to &maxtime by %eval(&interval*60);
output;
format time datetime.;
end;
run;


worked extremely quickly. I tried this originally but left out the do part of the statement so I figured it wouldn't work.
