Help with the Where clause proc print

Hi,

I am not sure why this would not work. Any suggestions? Thanks.

Libname Review'/folders/myfolders/Review' ;
Libname Learn'/folders/myfolders/Learn' ;  
Libname myformat'/folders/myfolders/sasuser.v94' ; 
Options fmtsearch=(myformat) ;

Proc Print data=learn.sales noobs ; 
	where Region eq ('North' AND Quantity lt 160) 
	OR Customer eq "Pet's are Us" ; /* Double "" because Pet's*/
run ;

I am getting the following error:

 69         Proc Print data=learn.sales noobs ;
 70         where Region eq ('North' AND Quantity lt 160)
 71         OR Customer eq "Pet's are Us" ; /* Double "" because Pet's*/
 ERROR: WHERE clause operator requires compatible variables.
 72         run ;

Thanks.

('North' AND Quantity lt 160)

is a test. It returns a boolean value (0 or 1).

Then you test region eq 1, which triggers the message as the values are of different type.

Your test is malformed. You probably mean

	where (Region eq 'North' AND Quantity lt 160) 
	   OR Customer eq "Pet's are Us" ;

Great, Thanks.

What about if I write the code:

Libname Review'/folders/myfolders/Review' ;
Libname Learn'/folders/myfolders/Learn' ;  
Libname myformat'/folders/myfolders/sasuser.v94' ; 
Options fmtsearch=(myformat) ;

Proc Print data=learn.sales noobs ; 
	where (Region eq 'North' AND Quantity lt 160) ; 
	where Customer eq "Pet's are Us" ; /* Double "" because Pet's*/
run ; 

This seems to only produce results for the second where clause (Pets are Us). Why is that?

the second clause replaces the first one.

is this home work?

Hi, I'm teaching myself SAS from Learning SAS by Example. It has answers to only the odd problems. Plus, it helps to learn the concept by going on here when I am truly unclear about something.
