• MySQL Sub-query.. Doesn't provide proper information after 3 entries into table.

  - by Chris Keefer

  After I get 3 rows in my forum_threads table this no longer does it's job; to organize a list of active forum threads and put the most recently responded-to thread at the top of the list, followed by second most recent posted-to thread, followed by third, fourth, etc. Like I said, the query works wonders up until there is a fourth row added to forum_threads. SELECT forum_threads.*, forum_posts.thread_id FROM forum_threads INNER JOIN (SELECT MAX(id) AS id, thread_id as thread_id FROM forum_posts group by thread_id order by id DESC) forum_posts ON forum_threads.id = forum_posts.thread_id

• Is there a way to get photo tags and new friendship type events by querying the FQL stream table?

  - by Fletcher Moore

  When you look at your stream on the Facebook website, events such as "FriendX was tagged in an album", "FriendY is attending EventZ", and "FriendK and FriendL are now friends". I've tried various "vague" queries on the stream table, and so far I have been unable to get these types of events. Is this possible, or do I need to query the all of the other tables and write a ton of logic to try to figure out which new events to show and how to show them?

• Need a good way to store data in a DB from a table on a webpage that can have N columns.

  - by Abe Miessler

  Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?

• C# SQL: What is the best way to implement a dynamic table?

  I want to allow the user to add columns to a table in the UI. The UI: Columns Name:__ Columns Type: Number/String/Date My Question is how to build the SQL tables and C# objects so the implementation will be efficient and scalable.

• JPA Is there a way to do something like SELECT <field>, count(*) FROM <table> GROUP BY <field>

  - by javydreamercsw

  I've been looking in the web for examples on the aggregates like count but it seems all of them are using the aggregate alone. SELECT field, count(*) FROM table GROUP BY field Should have something like: field.value1, x1 field.value2, x2 .... I'm looking for a pure JPA answer for this one. If not I guess I can then do further queries just for the count part but that seems unefficient. Any ideas?
