Increasing variable (while/sql)

Krohn — Wed, 15 Oct 2014 20:26:33 GMT

hi,

i'd like to increase a variable (payday) + 1 while it isn't a working day

how can i do something like that, using while and sql?

e.g:

create table new_payday as select

(while payday in ((select holiday from holiday_table),weekday(1),weekday(7)) then payday+1) as payday

from old_payday;

quit;

thanks

Not sure, but I think you are trying something like this

create table new_payday as

select

case when weekday(datepart(payday)) in (1,7) then payday+1 else payday end as payday

from old_payday;

quit;

If it was Saturday that would make the payday Sunday so that logic doesn't make sense for most businesses I know....

Look up the intnx function with the weekday option.

You can also create custom intervals to include your holidays, there's a few posts on here that cover how to do that.

A bit of a long read, but worth it, the very last example is what I'm referring to:

tomorrow im going to test it :smileygrin:

i can only test at job.....thanks

is there a way of using "while" inside proc sql?

I think you're looking for where instead. I'm not familiar with while in SQL though it's getting rusty...

However the intervalds option methodology with customized dataset would render that requirement for this question moot.
