How to apply the same code at once?

Hello all,

I have the code below that needs to be applied in all stocks of the data. So, if i have 800 stocks, I should run the code 800 times, each time changing the stock name (red highlighted). How can I make SAS automatically run the code for each stock and then save it as a file with the name of each stock?

Many thanks in advance  

proc sql;
create table C as
select*
from work.data
where stock = "ACERALIA";
quit;

proc sql;
create table b as
select date,code,value
from c;
quit;

proc sql;
create table f as
select a.*,b.*
from work.Date as a left join work.b as b
on a.date=b.date;
quit;

proc sort data=work.f nodupkey;by code date;run;
data a; set f; format date monyy7.; run;
proc sql; create table a_ as select distinct date,0.1 as code from a; quit;

data a2; set a a_;run;
proc sort data= a2; by code date;run;

Re: How to apply the same code at once?

Hi,

I tried the sample code and it works:

title;

data stocks;

input st $;

cards;

ibm

c

jmp

bp

/* put all your stocks in macro variable allstock */

proc sql noprint;

  select st into :allstock separated by ' '

    from stocks;

quit;

%macro test();

%do i=1 %to %sysfunc(countw(&allstock));

%let st=%scan(&allstock,&i);

proc print data=stocks;

   where st="&st";

   title from stock "&st";

Re: How to apply the same code at once?

Before anyone tries to show you what you've asked, it would be helpful if you posted sample data for the files involved and provided an explanation of what you are trying to accomplish.

The code you provided appears to do some things that appear odd.  First you create a table with just a certain value of stock.  Then you create another table, based on the table you created, but only containing 3 variables.  Then you join those two files.  Why?

Then you do a sort to get rid of duplicates.  That would probably be more easily accomplished using a distinct clause in your original proc sql.

I didn't try to follow the rest of the code because I didn't understand what you were trying to accomplish with the first parts.

Re: How to apply the same code at once?

is "asigns" your final output dataset?  and you want to replace "asigns" with stock name?  if so you can try the code below:

%macro test(st);

proc sql;

create table C as

select*

from work.data

where stock = "&st";

quit;

proc sql;

create table b as

select date,code,value

from c;

quit;

proc sql;

create table f as

select a.*,b.*

from work.Date as a left join work.b as b

on a.date=b.date;

quit;

proc sort data=work.f nodupkey;by code date;run;

data a; set f; format date monyy7.; run;

proc sql; create table a_ as select distinct date,0.1 as code from a; quit;

data a2; set a a_;run;

proc sort data= a2; by code date;run;

proc transpose data=a2 out=a3(where=(code^=0.1));

Re: How to apply the same code at once?

Thank you Linlin,

The macro works, but what i would like to do is not to have to change the Stock name each time, cause there could be thousands of stocks. Is there any way that SAS can do it automatically for each stock without me changing the stock name all the time? Maybe if i create a file with all stock names and then SAS looks at this file?

Re: How to apply the same code at once?

Many thanks Linlin, it works great!!!

May I ask one more question? Is there any macro that I can use to save all these files (in excel format) into one folder in my computer?

Many thanks again,

Re: How to apply the same code at once?

Hi Coastas,

I would follow Art and Astounding's suggestion to provide some sample data and your desired output. you will get a lot of good ideas and alternate solutions. there are a lot of  very talented experts on the forum and I have learned a lot from them.

for your question, the code below creates an excel file for each stock. Please modify the red part.

please ignore the warnings:

/*WARNING: File BP.bp.DATA does not exist.

WARNING: Table BP.bp has not been dropped.*/

data stocks;

input st $;

cards;

ibm

ge

co

c

jmp

bp

;

/* put all your stocks in macro variable allstock */

proc sql noprint;

  select st into :allstock separated by ' '

    from stocks;

quit;

%macro test();

%do i=1 %to %sysfunc(countw(&allstock));

%let st=%scan(&allstock,&i);

data &st;

   set stocks(where=(st="&st"));

   run;

%end;

%mend;

%test

%macro test2;

%do i=1 %to %sysfunc(countw(&allstock));

%let st=%scan(&allstock,&i);

/* using your own folder */

  libname &st "c:\temp\forum\&st..xls";

   proc sql;drop table &st..&st;quit;

    data &st..&st;

     set &st;

   run;

  libname &st clear;

%end;

  %mend;

  %test2

Re: How to apply the same code at once?

Costasg,

Both previous posters are likely to be 100% correct here.  You may find a program that will do what you ask.  But it also may take 500 times as long to run as an alternate solution.  Give us some information about your starting data and your desired result and you will get additional suggestions.

Good luck.

Re: How to apply the same code at once?

Thanks again Linlin. Ok, I am attaching some sample files.

Data: a small sample of my data

Date: a list of all dates (as not all funds trade on all dates)

Funds: the codes of all funds

Output: this is the final output for each stock (Ideally, I would like to keep only the new variables (s1,s2....) but rename them with the names of the old ones starting with the second date)

And here again is the code I apply:

proc sql;
create table C as
select*
from work.data
where stock = "ACERALIA";
quit;

proc sql;
create table b as
select date,code,value

from work.Date as a left join work.b as b

Re: How to apply the same code at once?

Since Art and Astounding have not responded yet. I will give a try:

proc sql;

create table b as

  select date,code,value

    from work.data

       where stock = "ACERALIA";

create table a as

  select a.date format=monyy7. ,code,value

    from work.Date as a left join work.b as b

on a.date=b.date;

quit;

proc sort data=work.a nodupkey;by code date;run;

proc sql; create table a_ as select distinct date,0.1 as code from a; quit;

data a2; set a a_;run;

proc sort data= a2; by code date;run;

proc transpose data=a2 out=a4(where=(code^=0.1) drop=_name_);

by code;

id date;

var value;

run;

proc sql;

create table a5 as

select a.*,b.*

from work.funds as a left join work.a4 as b

on a.code=b.code;

quit;

Data a5;
