Actually, all you're missing is some punctuation. Don't skimp on the ::
and () ! Plus, you should use explicit CASTs wherever you remember
them:
SELECT Invoices.InvoiceDate + INTERVAL(CAST(Acct.AverageDaysToPay AS
VARCHAR) || ' days');
Will work fine. Here I've explicitly cast the Average Days integer (if
it's NUMERIC or FLOAT, you will have to use TO_CHAR()) to varchar, then
concatinated it with the word "days". *Then* I convert it to INTERVAL,
which will recognize '# days' as a valid expression.
IMHO, you've been lucky being able to skip the parens and CASTs so far;
get used to using them.
