Hi,
Migrating an application from windows to linux, i am experiencing some
query building errors. For non trivial queries, involving parentheses,
the built query contains some extra '':'' character.
For instance, if input :conditions is:
is_spam != 1 and is_prohibited !=1 and is_archived !=1 and id in (select
ticket_id from categories_tickets where category_id in (select
category_id from category_ancestors where ancestor_id = 68))
The following code throws an error:
find(:all, :conditions => sql, :order => ''created_on
desc'', :limit =>
page_size, :offset => offset)
throws an error. The log indicates that the query contains some extra
'':'' :
You have an error in your SQL syntax. Check the manual that corresponds
to your MySQL server version for the right syntax to use near ''select
ticket_id from categories_tickets where category_id in (: SELECT * FROM
tickets WHERE (is_spam != 1 and is_prohibited !=1 and is_archived !=1
and id in (select ticket_id from categories_tickets where category_id in
(select category_id from category_ancestors where ancestor_id = 68)))
ORDER BY created_on desc LIMIT 0, 10
Anybody has experienced this kind of issues?
