What's wrong with my syntax?

[SASuser4321]

I have the following code with me:

proc sql;

create Table _final_ as

select final_slot, calc_client_slot, CASE

when final_slot = calc_client_slot then 0 

else 1                   

end as flag_    

from app_port;

quit;

but when I run it, it shows error. Here is the log:

675  proc sql;
676  create Table _final_ as
677  select final_slot, calc_client_slot, CASE
678                                       when final_slot = calc_client_slot then 0

                                                                                   76

681        from app_port;

Help would be appreciated. Thank you.

Is "vegetable" a variable?

Have you tried removing the parenthesis around "case"?

[Kurt_Bremser]

Do not post just the error message. Post the whole log of the step, so we see all the message(s) in context.

Copy/paste the log text into a window opened with this button:

I would use a data step:

data _final_;
set have (keep=fruit vegetable);
flag_ = (fruit ne vegetable);
run;

Please post a ready to paste example including a data step creating a mock table for _final_ that demonstrates the error.

NO need parent character if using CASE operator:

proc sql;
create Table _final_ as
select weight, height, CASE
when weight = height then 0
else 1
end as flag_
from sashelp.class;
quit;

Well the code you posted in the question is missing a spaces between some of the words.

17   data _null_;
18     infile example ;
19     input;
20     list;
21   run;

NOTE: The infile EXAMPLE is:
      (system-specific pathname),
      (system-specific file attributes)

RULE:     ----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0
1         proc sql;create Table _final_ asselect final_slot, calc_client_slot, CASEwhen final_slot = calc_clie
     101  nt_slot then 0 else 1                   end as flag_    from app_port;quit; 175
NOTE: 1 record was read from the infile (system-specific pathname).
      The minimum record length was 175.
      The maximum record length was 175.

If you just clean that mess up it seems to work without syntax errors. Of course you didn't give us any actual data to use to really test it.

39   proc sql;
40   create Table _final_ as
41    select final_slot
42         , calc_client_slot
43         , CASE when final_slot = calc_client_slot then 0
44                else 1
45           end as flag_
46    from app_port
47   ;
