What I would like is to have a do loop within PROC SQL instead of doing it in two steps with PROC SQL and then Data Step:
PROC SQL;
CREATE TABLE TEST AS
SELECT Quantity,
Price,
sum(DEC) AS total_DEC,
sum(Ingredient_Cost) AS total_ing_cost,
(Calculated total_DEC-Calculated total_ing_cost)/ Calculated total_DEC AS discount,
(Calculated total_DEC*(1-.82)) format=8.2 AS target_ing_cost,
(Calculated total_DEC-Calculated target_ing_cost)/ Calculated total_DEC AS target_discount
FROM EGTASK.DATA_EXAMPLE;
QUIT;
data TEST_2;
set TEST;
do i=.8 to 1.2 by .01;
target_cost = Price*Quantity*i;
output;
end;
run;
What I want is to accomplish what is being done in the data step in the PROC SQL instead (do it in one step). Is this possible?
Why not just make the list of values as a separate table and join with it?
data list_of_values;
do i=.8 to 1.2 by .01;
output;
end;
run;
proc sql;
create table TEST as
select a.*
, a.price*a.quantity*b.I as target_cost
from (
select Quantity
, Price
, sum(DEC) as total_DEC
, sum(Ingredient_Cost) as total_ing_cost
, (Calculated total_DEC-Calculated total_ing_cost)/ Calculated total_DEC as discount
, (Calculated total_DEC*(1-.82)) format=8.2 as target_ing_cost
, (Calculated total_DEC-Calculated target_ing_cost)/ Calculated total_DEC as target_discount
from EGTasK.DATA_EXAMPLE
) a
, list_of_values b
;
quit;
