[ale] [OT] - SQL question and fastest sorting algorithm

[Jason Vinson]

first a question for the DBA/SQL coders out there:

I have a table that i want to grab data out of by referencing two 
separate keys as follows:

select create_time, info from table_notes where case2notes = 12345 or 
subcase2notes in (select from table subcase where subcase2case = 12345)

 From what i understand, you can't do a join on the same table with two 
separate keys, and this method is horribly inefficient (read that as it 
kills my schema browser to even run that command) and i wanted to see 
if there was a better way to request this data, or if i would be better 
off just getting all the data from separate queries and then using a 
sorting algorithm by date.

which leads me to my second question:  what's the most efficient 
sorting algorithm by most standards?

TIA,
Jason
