Data subsetting.

msharma1788 — Wed, 21 Feb 2018 18:39:03 GMT

Data Set name is PLN200

SSN PLAN_ID CV_CAT

001 9000 21
001 9020 847

My code is not giving me expected result:

DATA PLN200;
SET PLN200;
BY SSN;
IF PLAN_ID = 9000 AND PLAN_ID = 9020 THEN DO;
IF CV_CAT IN(26,55,65,817,827,847) THEN DELETE;
END; RUN;

I am expecting only "001 9000 21 " in result.

Please suggest.

It is not possible for PLAN_ID to be equal to both 9000 and 9020.

Use OR instead of AND, or better yet:

IF PLAN_ID in (9000, 9020) THEN DO;

Simply,

IF PLAN_ID = 9000 OR PLAN_ID = 9020 THEN DO;

You also can check the condition at the same time:

DATA PLN200;
SET PLN200;
BY SSN;
IF not ( PLAN_ID in ( 9000, 9020) and
CV_CAT IN(26,55,65,817,827,847)) ;
RUN;

I need the data to be deleted only when the SSN is in both the plans 9000 and 9020 , If its in both the plans then it should check the CV_CAT ids mentioned. and should delete that row.

So you need to check multiple rows first to see if that SSN has both 9000 and 9020, does that sound correct?

Since all the data is not in one row your logic needs to be significantly different.

A DATA step is limited to processing one observation at a time. Here's a way to program around that for your purposes:

data want;

merge

pln200 (where=(plan_id=9000 in=in_9000))

pln200 (where=(plan_id=9020 n=in_9020))

pln200;

by ssn;

if in_9000 and in_9020 and CV_CAT IN(26,55,65,817,827,847) THEN DELETE;

run;

The order of the data sets in the MERGE statement is important. The PLN200 with no WHERE condition must be last.

Hi,

Check this one using CALL SYMPUT

DATA HAVE;
INFILE DATALINES dlm=" ";
INPUT SSN PLAN_ID CV_CAT;
datalines;
001 9000 21
001 9020 847
;
run;
proc sort data=HAVE;
by SSN PLAN_ID;
run;

DATA WANT;
SET HAVE;
BY SSN PLAN_ID;
IF FIRST.SSN THEN CALL SYMPUT("Hold"," ");
IF PLAN_ID=9000 THEN CALL SYMPUT("Hold","YES");
IF PLAN_ID=9020 and SYMGET("Hold")="YES" and CV_CAT IN(26,55,65,817,827,847) THEN DELETE;
RUN;
