Hi
I have 2 data sets (Current and Prev month).
I need to compare the 2 datasets no. of observations and if the current month data set has more no. of records then I need to run or call a macro?
How do I achieve that?
Try this....
proc sql noprint;
select nobs into: curr from dictionary.tables
where upcase(libname)="MYLIB" and upcase(memname)='MY_CURR';
select nobs into: PREV from dictionary.tables
where upcase(libname)="MYLIB" and upcase(memname)='MY_PREV';
QUIT;
%macro HasMore;
%if %eval(&prev<curr) %then %do;
%MyMacro;
%end;
%mend
%HasMore;
Hope this helps.
Like this?
data _null_;
if NOBS1 ne NOBS2 then call execute('%mymacro;');
set TABLE1 nobs=NOBS1;
set TABLE2 nobs=NOBS2;
stop;
run;
Simple since there is no macro language, and fast since we don't use the dictionary.
Thanks Chris it did the job for me....
Any specific reason why the if logic before reading the data sets?
nobs are obtained during compile time so they can be used before SET statement.
If you put it after the SET statements and one of the data sets is empty, it will never be executed.
start using Proc Compare ..
