Hello Techiez,
I need help to get total count of observation in all dataset from a Library.
Suppose a library contains 50 datasets(tables).
Some table have X observation , some has Y observation.
Want total count of all the datasets.
thanks in advance.
Regards,
Ritesh
This example uses work library, but you can substitute your own lib:
proc sql;
select sum(nobs) as TotalRows
from dictionary.tables
where libname eq 'WORK';
quit;

thanks nehalsanghv you really solved my query.
A new question came to my mind realted to same.
Suppose A library contains 100 dataset, and i want only 50 dataset count ( selective dataset).
Is it possible?
thanks in advance.

Dataset names are listed in the memname column of dictionary.tables. You can list the memname values you want in the where statement. Give the entire dictionary table a look with a select *, there is a lot of useful metadata.
proc sql;
select sum(nobs)
from dictionary.tables
where libname = 'WORK'
and memname in ('TBL1','TBL2');
quit;
Better use NLOBS .
proc sql;
select sum(nlobs) as TotalRows
from dictionary.tables
where libname eq 'WORK' and memname like '%XX%';
quit;
