Need a macro to run daily data for unlimited number of days

I have a code which I am running to join data for certain number of days but now I need to extend the same code for unlimited number of days using a macro. Can anyone please help.

Regards

proc sql;
create table f.rprt as 
select 
a.TY_NUMBER as TY_NUMBER,
a.IO_NUMBER  as  a_IO_NUMBER,		
b.IO_NUMBER  as  b_IO_NUMBER,		
c.IO_NUMBER  as  c_IO_NUMBER,

Is your question: how to run this code every day?

Or is the question how to modify the code so it runs properly on a future day?

Or is the question something else?

Initially I was running this code for few days let say 5 so I was able to hardcode all days dates in the join condition but now I need to run this for about 33 days so need a macro which can automatically replace the table name in the join condition to use all available dates and join data for all those 33 days.

Thanks, I think I understand now.

Suggestion: instead of this data structure

a.IO_NUMBER  as  a_IO_NUMBER,		
b.IO_NUMBER  as  b_IO_NUMBER,		
c.IO_NUMBER  as  c_IO_NUMBER,		
d.IO_NUMBER  as  d_IO_NUMBER,
e.IO_NUMBER  as  e_IO_NUMBER,

which creates a wide data set, much easier to program if you create a long data set instead. And also it is much easier to perform follow-up analyses when you have a long data set.

If you'd like to go that way, let me know.
