As should be obvious, this is stock market data. I want the query to
return only the results where the max date is less that 2013-07-02.
In other words, your query is returning a row for every symbol, not
just the ones that haven't been updated. Have any thoughts?
Explaining your use-case the first time around would have been helpful.
WHERE clauses operate on the data before the GROUP BY operation.
You want to be using a HAVING clause, which operates on the data after
the GROUP BY operation.
select localSymbol, max(localDate2)
from tre_xignite
group by localSymbol
having max(localdate2) < '2013-07-02'
