...Here is one case in relations_test.rb. Can someone look at this and just tell me it is normal for other DBs and just odd for SQL Server? Or maybe it is just my understand of some SQL standard. I''m really not that SQL smart. Honestly. def test_count_explicit_columns Post.update_all(:comments_count => nil) posts = Post.scoped ... assert_equal 0, posts.where(''id is not null'').select(''comments_count'').count ... end OK, this passes in standard DBs, postgresql, sqlite3, and mysql.

...the number of belonging objects on the associate class through use of increment_counter and decrement_counter. The counter cache is incremented when an object of this class is created and decremented when it?s destroyed. This requires that a column named "#{table_name}_count" (such as comments_count for a belonging Comment class) is used on the associate class (such as a Post class)." So, all that''s possible is incrementing/decrementing "#{table_name}_count" when an item is created or destroyed. I think it''d be useful if :counter_cache also had this functio...
