Webmaster Forum / ASP / Database Access / October 2008

Hi All

I use a MySQL DB with my ASP classic web app.

I've been asked if I can create a routine whereby I get a random number of
products (records) from the DB and display these on the site.  Basically
every time a visitor hits the home page, they want the site to display a
random selection of say 6 products.

I have no problems getting the data and displaying it, my problem is
grabbing 6 random records efficiently.

My initial thought was bring back all of the records to a local array (like
I normally do) and then pick 6 random records in VBscript, but if a DB has
12,000 products this is a silly server hit to bring them all back just to
display 6 out of the 12,000.

The products table doesn't have an auto-number field, the unique-ness is
managed by the product's own unique stock code, but this isn't a sequential
number - its alphanum.

Any ideas on how I can get 6 randoms from the DB rather than bringing all
locally?

Thanks
