Calculate a missing field

D_Z_ — Tue, 28 Feb 2012 23:59:03 GMT

I am attempting to do a calculated column in my SQL that takes

Merchandise_AMT - Changed_Price

There are several instances where the value in changed price is '.' I tried doing a missing statement to replace all '.' with '0' but the calculation had the same affect. Does anyone know how to treat the '.' as an actual zero so the calculation will work as intended?

I can't test it at the moment, but how about if you use the sum function? e.g.:

data have;

input x y;

cards;

1 2

1 .

5 7

7 5

. 6

;

proc sql;

create table want as

select *,sum(x,y*-1) as diff

from have

;

quit;

Art297 has a good suggestion.

I have also used this method with success - basically I test if Price is empty and only do the calculation if it's not. My else value can be 0 indicating no change or it could be amount if that makes more sense in your calculation.

,case

when price ge 0 then Amt - price

else 0 /*You may want this to be Amt*/

end as new_var
