2005 to 2000

Is it possible to convert a sql2005 features to sql2000?
Because the ISP server there's no way to install the 2k5 server. Or do you
have a statment that can generate a table filled only with the workdays of a
year on ms sql 2000. THank you very much

But for crying out loud! Find a new ISP, and the current rot away
with its SQL 2000!

In this particular case, it's fairly easy. Rather than using a number
of CTEs, use a number nested derived tables:

FROM (SELECT ...
FROM (SELECT ...
FROM ...) AS Years
CROSS JOIN (SELECT FROM ... ) AS Months
...) AS DatesRaw
LEFT JOIN ( ) As Holidays

But you cannot do recursive derived tables. But you can easily replace
them if you use a table number of numbers to span years, months and
days. See http://www.sommarskog.se/arrays-in-sql-2005.html#tblnum
