SQL & PL/SQL

Hello,

I have a column table where I have all holidays of the year in the format "yyyymmdd,yyyymmdd,...", for example, "20091012,20091225".

I'd like to do a query where I pass a date and a increment of days and it returns the next valid date, excluding weekends and the holidays that I have in the column holidays that I show above.

P.S: Instead of pass a date and a increment of days, I could pass just a already incremented date, and this query just validate this date, adding 2 days for each weekend and one day for each holiday.

Is there a way to do that?

Thanks
