Slightly confused. I can issue the select statement from the query browser, but if I issue it through JDBC I get the following error. I don't suppose you know why do you?

Cheers,
Jon.

SELECT SUBSTRING(MAX(CONCAT(LPAD(time, 20, '0'), data)), 21) FROM storm GROUP BY name
SQLException: Column 'data' not found.
