Data sorting as per two variable which has missing values?

k26_23 — Mon, 23 Jun 2025 19:29:44 GMT

I need to sort the table A below in which the values needs to be in the output as per the variable 'Sort-order' and when variable 'ID' is not missing i need all the same ID values data to grouped (like all the TL01 values one by one and then followed by all TL02 and all TL03 values etc...)

example the input data set looks like this :

Table A

Subject	Site	ID	Description	Parameter	Parameter description	Sort-order
101-276	101			NTLDAT	Date of Assessment	01
101-276	101	NTL01	CARCINOMATOSIS:CARCINOMATOSIS	NTLSTAT	Status	02

Re: Data sorting as per two variable which has missing values?

Tom — Tue, 24 Jun 2025 00:25:57 GMT

I do not understand what you are saying. Can you make a better example that more clearly shows what it is that you need to do?

The current dataset does not really help explain the issue very well. Subject and Site are constants. SORT_ORDER seems to be the same as PARAMETER/PARAMETER_DESCRIPTION.

And there are not that many ties for the value of SORT_ORDER . Only 04, 05 and 06 have more than 2 observations. And those all have unique values of ID.

Hello @k26_23,

Try this:

/* Create temporary variable describing block structure */

data _tmp / view=_tmp;
set have;
by subject site;
_block=ifn(first.site,1,sum(_block, (id=' ') ne (lag(id)=' ')));
retain _block;
run;

/* Use the temporary variable to obtain the desired sort order */

proc sql;
create table want(drop=_block) as
select * from _tmp
order by subject, site, _block, id, sort_order;
drop view _tmp;
quit;

Hi k26_23,
What dataset is this ? What is NT, NL, and TL? Are they domain name or specific column (eg., like link id) values?

Re: Data sorting as per two variable which has missing values?

dxiao2017 — Tue, 24 Jun 2025 18:07:18 GMT

Hi @k26_23 , this is your data set A. I have not figure out the solution for your request, also I do not quiet understand the intention of your request, i.e., what kind of dataset you would like to create, and what's for?

It looks to me like you are working on a dataset that has link ID to other datasets. But what's the sort-order column for? Looking from your dataset A, this column is character (if it is numeric the '01' to '06' would be displayed like '1' to '6', without the leading 0), so what's this column for (I converted this column to numeric, incase it is needed as an order variable)?

And it looks to me like, by the sort-order column you created a number for each Parameter column value, if so why not just order your data according to the Parameter column? Are you prompting some convoluted question and a false request that confused yourself? I tried some sql step but did not get the dataset you request. I'll post it here also.
