The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

I am working on some SQL statements for an ASP.NET application. One of the
things that is required is to only display information in an open period.
The period is updated automatically by the vendor software as the previous
period is closed. So I finding myself doing a bunch of sub selects like:
where date >= (SELECT DATE(CONCAT('20', CONCAT(YY, CONCAT('-', CONCAT( MM,
(CONCAT('-', DD))))))) FROM LIB/FILE')
Yes, each portion of the date is in separate fields.
Would making this query a function make the query more efficient? I have
never created a function before how would I do that? My thought is having
something like:
IsInRange(date)
So I can do "WHERE IsInRange(date)".
Or is there a better way?
