I'm trying to execute some Proc SQL conditionally, based on the value of a global macro variable (&pen_ts). I attempted to do it with call execute () but it tells me the quoted string is too long. This is what I'm trying to do:
data _null_;
length longstr $ 200;
longstr = "proc sql;
create table risk_assess as
select distinct compound_id,
code,
penalty_id,
track,
min(seq) format=4. as min_of_seq
from ps.tent_buy
where code = '02603026'
group by compound_id, code, penalty_id, track
having seq = min(seq);
quit;";
if &pen_ts = 'TS' then call execute (longstr);
run;
Any suggestions? Thank you...
Hi,
1) why not to use macro, it seems to be easier to maintain:
%macro doSQL()
%if &pen_ts = 'TS' %then
%do;
proc sql;
create table risk_assess as
select distinct compound_id,
code,
penalty_id,
track,
min(seq) format=4. as min_of_seq
from ps.tent_buy
where code = '02603026'
group by compound_id, code, penalty_id, track
having seq = min(seq);
quit;
%end;
%mend doSQL;
%doSQL()
2) Does macrovariable pen_ts contains `'TS'` (with single quotes) as the value or `TS` (without quotes) as the value? This is important to check the %if condition
since for macrolanguage text `'TS'` not equals to text `TS`
All the best

Hi,
The message about quoted string too long is just a warning. You can turn it off with system option noquotelenmax.
That said, if your goal is to execute a PROC SQL step (or any step) conditionally based on the value of a global macro variable, typically you would use a macro %IF statement for that, e.g.:
%if &pen_ts=TS %then %do ; %*I am assuming your macro variable does not have quotes in the value;
proc sql;
create table risk_assess as
select distinct compound_id,
code,
penalty_id,
track,
min(seq) format=4. as min_of_seq
from ps.tent_buy
where code = '02603026'
group by compound_id, code, penalty_id, track
having seq = min(seq);
quit;
%end ;
If you're not on a recent version of SAS, you will get an error about %if not valid in open code. If that happens, you can create a macro, which is probably a good idea anyway, as you can trade the global macro variable for a local macro parameter:
%macro runquery(pen_ts=);
%if &pen_ts=TS %then %do ; %*I am assuming your macro variable does not have quotes in the value;
proc sql;
create table risk_assess as
select distinct compound_id,
code,
penalty_id,
track,
min(seq) format=4. as min_of_seq
from ps.tent_buy
where code = '02603026'
group by compound_id, code, penalty_id, track
having seq = min(seq);
quit;
%end ;
%mend runquery;
%runquery(pen_ts=no) /*will not execute SQL*/
%runquery(pen_ts=TS) /*will execute SQL*/
%runquery(pen_ts=&pen_ts) /*will pass the value of global macro var to the parameter*/
Once you have written that macro, you'll start seeing additional parameters that might be useful (name of table queried, name of table to create, code ...)
