This is also true.
Can you 'detatch' your index? By this I mean store the index on a different

Also what type/size machine are you running your query on? How much memory?
What else is in the table? Are the rows fat?

So the fact that even on a single table, it looks like your results are in
order of your identity index and it ignores the order by clause.
Your second index on the value doesn't appear to be used unless it's a
filter before the join and then the join uses the identity index.
Since you're a bit cryptic..
On Table A, you show Col_x_ID, but in your foreign key, you show Col_x. I'm
going to assume that you meant Col_x_ID.
On Table A, do you have an index on Col_x_ID? Is Col_x_ID a unique ID? If
so, is this the primary key for the table?
