In a library if there are 10 datasets and I would like to get the total number of observations from all the 10. is there any way other than using the proc sql and giving the each dataset name?

Hello SASPhile,

This is my solution:

[pre]

proc SQL noprint;

select COUNT(distinct memname) as N into :N

from SASHELP.VMEMBER where libname="WORK" and memtype="DATA";

%let N=%TRIM(&N);

select distinct memname as name into :N1-:N&N

from SASHELP.VMEMBER where libname="WORK" and memtype="DATA";

quit;

%macro a;

%local i obs;

%global nobs;

%do i=1 %to &N;

proc SQL noprint;

select COUNT(*) as obs into bs from &&n&i

;quit;

%if &i = 1 %then %let nobs=&obs;

%let nobs=%EVAL(&nobs+&obs);

%end;

%mend;

%a;

%put nobs=&nobs;

[/pre]

Sincerely,

SPR

This displays name and count:

[pre]

%macro a;

%local i obs;

%do i=1 %to &N;

proc SQL noprint;

select COUNT(*) as obs into bs from &&n&i

;quit;

%put DATASET=&&n&i obs=%TRIM(&obs);

%end;

%mend;

options nonotes;

%a

oprions notes;

[/pre]

Try something like this (replace the SASHELP libref with your libref of interest - make sure you type the libref in all caps):

proc sql;

title 'Total Observations for all datasets in the SASHELP library';

select sum(nlobs) 'Total Observations' format=comma16. as TotObs

from dictionary.tables

where libname ='SASHELP'

and MEMTYPE='DATA'

;

title 'Observations for each dataset in the SASHELP library';

select MEMNAME 'Dataset', sum(nlobs) 'Obs' format=comma16. as Obs

from dictionary.tables

where libname ='SASHELP'

and MEMTYPE='DATA'

group by MEMNAME

;

quit;

proc sql;

title 'Total Observations for all datasets in the SASHELP library';

select sum(nlobs) 'Total Observations' format=comma16. as TotObs

from dictionary.tables

where libname ='SASHELP'

and MEMTYPE='DATA'

;

title 'Observations for each dataset in the SASHELP library';

select MEMNAME 'Dataset', sum(nlobs) 'Obs' format=comma16. as Obs

from dictionary.tables

where libname ='SASHELP'

and MEMTYPE='DATA'

group by MEMNAME

;

quit;

proc contents data=work._all_ out=sum(keep=memname nobs);

set sum end=last;

total+nobs;

output;

if last then do;
