I was going to give you a doc reference but then realized I couldn't
find it in the new documents. 8-\

[query  list=1
	sql="select * from products where category = 'something'"
	] [sql-param sku] [sql-param category] [/query]

would be the normal form for doing quick lists.

I couldn't find this either, though I know I wrote the doc:

    <FORM HREF="[area @@MV_PAGE]">
    <SELECT NAME=category>
            [query list=1
		sql="select distinct category from products order by category"]
            <OPTION>[sql-code]</OPTION>
            [/query]
    </SELECT>
    <INPUT TYPE=submit>
    </FORM>
    <P>

    [if cgi category]
    [query
       list=1
       sql="
            SELECT * FROM products
            WHERE category = '[cgi name=category filter=sql keep=1]'
            "]
            [sql-param sku] [sql-param category]<BR>
    [/query]
    [/if]

There is supposed to be some stuff to automatically use the value of variables
as the search specification, but I can't for the life of me get it to work
at the moment or even find the docs about it. I will fix that. 8-)
