Re: SQL: Select only rows with Max Value on a Column
#2I prefer SELECT table.*
FROM table
WHERE rev = (SELECT MAX(rev) FROM table WHERE id=table.id)
I hate joins. Subselects are so much clearer imo - and you don't end up with extra fields.

#3Or those who happen to be using a dialect of sql with window functions, selecting the rows where:
ROW_NUMBER() OVER(PARTITION BY Id ORDER BY Rev DESC) AS "Row Number"
Returns 1 is clearer to my mind, with some caveats around dialects which use separate forms of row-number that assign identical/differing numbers to two consecutive identical rows.
