I'm trying to create a dataset linking to Oracle, but I'm having problems getting a case statement to work in the query. It works fine in SQLPlus, Sql developer.
When I try and add the statement it either puts single quotes around the statement, or throws the error 'Invalid or missing expression'.
Here is the query in question:

I'm making a simple forum using MySQL and I use a repeater to display a list of all threads in it. I have two tables for posts, one for threads and one for replies, and I want to sort the threads by either when they were posted or when the last reply was posted in it. My SQL query is really long and hard to read so here's some psuedo code similar to it (easier to understand these column names, etc):
SELECT
threads.id,
threads.title,
threads.timestamp,
users.username,
(SELECT COUNT(*) FROM replies WHERE thread_id = threads.id) AS number_of_replies,
(SELECT COUNT(*) FROM views WHERE thread_id = threads.id) AS number_of_views,
(SELECT timestamp FROM replies WHERE thread_id = threads.id ORDER BY timestamp DESC LIMIT 1) AS last_reply_timestamp
FROM threads
LEFT JOIN users
ON threads.user_id = users.id
ORDER BY ************** DESC
What I do here is I fetch the values id, title, timestamp, the author's username, the number of replies and views for a specific thread, and I also get the timestamp for the last reply to this thread.
Then, what I want to do is sort the whole list so that the threads are displayed in an order matching when either it was posted or the last reply was posted in it (you know, like a normal forum) but I'm not sure how to accomplish this.
I tried this:
ORDER BY CASE WHEN last_reply_timestamp > threads.timestamp THEN last_reply_timestamp ELSE threads.timestamp END DESC
but that, I guess, maybe only looks at the first row and determines which one should be used so the order is not correct.
I'm not sure if it's possible to create a sort of variable that holds the value for each row of the timestamp that applies, if that's possible you could sort by that. For example:
(CASE WHEN last_reply_timestamp > threads.timestamp THEN last_reply_timestamp ELSE threads.timestamp END) AS last_activity_timestamp
...
ORDER BY last_activity_timestamp DESC
So each row has a field "last_activity_timestamp" containing either timestamp, whichever is the later than the other.
Can this be done somehow? How does everyone else solve this? It's so hard to search google because I just get lots of forums but no code.

I have a web site which uses one SQL database but the hosting company is very slow sometimes and I got database timeout, login and similar errors. Can I implement my code to use two databases simultaneously? I have stored procedures and the data is updated periodically.
EDIT:
Simply: When dbDefault is down and inaccessible I need to use dbSecondary so the web app keeps running. Ant these two databases must be always same.
EDIT:
Some errors:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.Cannot open database "db" requested by the login. The login failed. Login failed for user 'root'.

I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.

Is is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.
