Subject: [postmodern-devel] Converting a SQL statement with subquery into
	S-SQL
Message-ID: <9aa76dc50912260623reb41ab0j17c1cb6d721ed581@mail.gmail.com>

Hi All,

I'm trying to make the following SQL statement lispy by converting it to
s-sql:

    SELECT * FROM filter

    WHERE title

    IN ( SELECT filter_title FROM user_filter WHERE user_id = 4);

Here's my best attempt:

    :SELECT '* :FROM 'filter

    :WHERE 'title

    :IN (:SELECT 'filter_title :FROM user_filter :WHERE (:= 'user-id 3))

However, I get the following error:

    Keyword WHERE takes exactly one argument

I've tried the SQL query in psql so I know it works, but I can't seem to
come up with an equivalent s-sql statement.

Thanks for any assistance,

Sam

(:select '* :from 'filter :where
    (:in 'title (:SELECT 'filter_title :FROM user_filter :WHERE (:= 'user-id
