Need to Create Macros More Efficiently

I am trying to create multiple macro variables based on various conditions. Below is my code. I am not sure whether this is the most efficient way.

*to get total number of obs and max value of count variable where count<5;

proc sql noprint;

select count(*),max(count)

into : count1, count2

from dataset1

where count<5

;quit;

*to get total number of obs and max value of count variable where count>=5;

proc sql noprint;

select count(*),max(count)

into : count1, count2

from dataset1

where count>=5

;quit;

*count of name where count>=5;

proc sql;

select count (distinct name) into:cnt

from dataset1

where count>=5;

quit;

*count of name where count<5;

proc sql;

select count (distinct name) into:cnt

from dataset1

where count<5;

quit;

*get names into macro where count<5;

proc sql

select distinct name into : name1-:name&sysmaxlong

from dataset1

where count<5;

quit;

repeat the above step for count>=5


Is there a shorter/more concise way for the above. Will appreciate inputs on a more efficient approach.


Thanks!

Re: Need to Create Macros More Efficiently

Are you worried about performance?

It seems that most of these SQL can be merged into one query, by using CASE in the select clause, instead of using a where clause.
