[Zope] sql query that has 1 row result

[Service Informatique CHSR]

Hello,

Let sql_count_bucks be:

SELECT count(*) as Number FROM MyBucks

I know that this query will always have *one* row, and i want to use this
value. Is there a better way of writing this than:

<!--#var "sql_count_bucks()[0]['Number']"-->

kinda unreadable, isn't it? Another example: suppose i want a document to
display an article given the article id in a database. That is, i want to
display the article whose id is 2 with http://mysite.com/document?id=2
As id is the primary key, i know there will always be one article that match
the query. Is there another (better) way to write:

<!--#with "sql_query_article(REQUEST)[0]"-->
Article title: <!--#var title--><p>
Article content: <!--#var content--><p>
<!--#/with-->

It's not very important, because this way of writting works, but i wonder,
just in case i missed something in the FM.

Regards,
Jephte CLAIN
