How to suppress empty output from proc sql

[JMS]

The following code gives an empty result page:

ods listing close;                                              
ods html;                                                        
title 'report 1';
proc sql; select * from sashelp.class where age=99; run; quit;  
ods html close;                                                  
ods listing;       

How can I suppress the empty page when proc sql does not return a result?

You'll need macro logic. The easiest is to pipe it to a table and then check if the table is empty. If so, don't do anything and if it has records you can then print it using PROC PRINT.

Example of conditional logic is here:
