ORDER BY DESC LIMIT 1 is much simpler and more readable than a sub-query. Though the sub-query approach looks to be a good template for ensuring more accurate results by being more explicit.
Scott, how would a subquery "ensure more accurate results by being more explicit"?
Good question. I'm just now starting to construct sub-queries. Perhaps naively,
I assumed that setting g.date explicitly equal to the results of a MAX function
would return more reliable results than limiting a return list to just the first value
listed. Though it's entirely possible that both approaches use the same logic
under the hood.
Nonetheless, I'm using the DESC LIMIT 1 approach for now as it yields the
results I need and is much more readable.
Thanks again! Scott
