count

I have a data set as shown below:

ID	filing number
2115389	2012-09-13
2115389	2011-10-06
2115389	2008-04-09
11765414	2011-08-08
11765414	2011-07-11
16316120	2014-07-23
16316120	2009-12-18

How would i compute a third colum called COUNT?

ID	filing number	count
2115389	2012-09-13	1
2115389	2011-10-06	2
2115389	2008-04-09	3
11765414	2011-08-08	1
11765414	2011-07-11	2
16316120	2014-07-23	1
16316120	2009-12-18	2

proc sql;

create table WANT as

select *,

COUNT(*) as COUNT

from HAVE

group by ID,

FIL;

quit;

This is the way i wrote the code:

PROC SQL;

CREATE TABLE WORK.NAME AS

SELECT t1.'IDNumber'n,

t1.'Business Name'n,

t1.'Secured Party Name'n,

t1.'Filing Number'n,

t1.'Collateral Type'n,

t1.'Filing Type'n,

t1.'Filing Dt'n,

COUNT(*)as Count

FROM NEED t1

GROUP BY t1.'ID Number'n,

t1.'UCC Filing Dt'n

ORDER BY t1.'ID Number'n,

t1.'UCC Filing Dt'n DESC;

QUIT;

But i do not get the output like the one above.

Thanks,

You select 'IDNumber'n but group and order by 'ID Number',n

Could that be your problem?

Hi Arthur,

I have an example showing what the output should look like.

Thanks,

Arthur is correct, you have this line:

SELECT t1.'IDNumber'n,

Note that there is no space between ID and Number.

GROUP BY t1.'ID Number'n,

This is with a space.

Then IDNumber and Business Name do not appear in your spreadsheet screenshot.

Then you don't DESC on a group by.

Thirdly I would suggest getting your data out of Excel and into SAS, i.e. a dataset, then working with the dataset. Excel is not a useful tool for any operation and I would avoid it entirely.

Finally, the principal is that you group by the columns you want to count the distinct values of, so group by and select should be the same. If thats not what you want, i.e. it looks like you want more columns in the select than the group by I would suggest you subquery the count and left join it back on. I am out of office now for a few days, so good luck.

If you want the result shown in your last example, it will be a lot easier to do it using a sort and data step. e.g.;

proc sort data=need;

by 'Duns Number'n 'UCC Filing Dt'n;

run;

data want;

set need;

by 'Duns Number'n;

if first.'Duns Number'n then Count=1;

else Count+1;

run;

Hi Arthur,

Just a small change

data want;

set need;

by 'Duns Number'n;

if first.'Duns Number'n then Count=0;

else Count+1;

run;

Thanks,
