Can the SAS code include a #?

Sandeep77 — Thu, 08 Dec 2022 11:01:06 GMT

Hi, I have written a code where the address is mentioned in the table header with a # (dr_address##1). When I run the code, it shows an error. Could you please let me know what's wrong in my code? Thanks.

proc sql;
create table Customer_info as
select a.*,
b.dr_title,
b.dr_inits,
b.dr_name,
b.dr_address##1,
b.dr_address##2,
b.dr_address##3,
b.dr_address##4,
b.dr_postcode,
b.dr_phone,
b.dr_phone2,
b.dr_phone3,
b.dr_dob as Date_of_birth,
b.dr_email as email_address,
case when b.dr_phone is not null or 
b.dr_phone2 is not null or 
b.dr_phone3 is not null then 'Y' else 'N'
end as Number_available,
case when Email is not null then 'Y' else 'N'
end as Email_available
from Acc_level_plans as a
inner join p2scflow.debtor as b on a.debt_code=b.debt_code;
quit;

A SAS variable name can not contain a '#'. You can read about naming conventions of SAS variables in the Rules for Variable Names Documentation.

Thank you.

Hello All,

By default, the only special character a SAS variable name can include is _ (an underscore). However, you can use special characters like #'s as part of the SAS variable name if you use a SAS name literal (Example: 'dr_address##1'n) and the VALIDVARNAME system option must be set to ANY (options validvarname=any;). This will allow the use of non-standard characters as part of the variable name.

Here is an example using SAS Name literals in a SQL query, since the original question posted included a SQL query. You can also use SAS Name literals to create variables in a DATA step.

You can copy, paste this code and submit it in a SAS environment to see the results:

options validvarname=any;

proc sql;
create table nonStandardNames as
select make, model, invoice, mpg_city,

'1234 SAS Campus Dr.' as 'dr_address##1'n,
'Cary' as 'dr_address##2'n,
'NC' as 'dr_address##3'n ,
27513 as 'dr_address##4'n
from sashelp.cars
where mpg_city >40;

title "Non-Standard Names";
title2 "Using SAS Name Literals 'dr_address##'n ";

select make, mpg_city, 'dr_address##2'n, 'dr_address##3'n
from nonStandardNames;
quit;

proc contents data=nonStandardNames;
run;
