Question

I get this error:

The maximum recursion 100 has been exhausted before statement
completion

when I run this function:

    WITH allDays AS (

        SELECT @DateEarly AS date

        UNION ALL

        SELECT DATEADD(dd, 1, date) as date
        FROM allDays s  
        WHERE DATEADD(dd, 1, date) <= @DateLate


   )
    SELECT *
    from allDays 
    where dbo.isFestivo(date)>0

I tried to append this option:

OPTION (MAXRECURSION 200);

but i get an error 156 before “option” word.
Do you know why?

Answer 1

You’re probably putting the option in the wrong place. It needs to be after the where

WITH allDays AS (
    SELECT @DateEarly AS date
    UNION ALL
    SELECT DATEADD(dd, 1, date) as date
    FROM allDays s  
    WHERE DATEADD(dd, 1, date) <= @DateLate
)
SELECT *
from allDays 
where dbo.isFestivo(date)>0
option (maxrecursion 200);

But try this instead. It’ll be quicker…

select DATEADD(d, number, @dateearly) as [date]
from master..spt_values 
where type='p'
and number<=datediff(d,@dateearly,@datelate)
and dbo.isFestivo(date)>0
