Anyone see why this should fail? [message #144451]

I have a MySQL query where I want a difference in times between two dattime
fields. In testing, if I run this query in a MySQL client application (not
Birt)...

SELECT TIMEDIFF('2006-02-24 09:59:31','2006-02-01 00:00:00') as tdiff

then I get a result - 561:59:31.

If I run the exact same query in Birt, and try and preview the result, I get
the following error:

A BIRT exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine
Plug-in ID:org.eclipse.birt.data
Version:2.0.1
Error Code:odaconsumer.CannotGetTimeFromColumn
Error Message:Cannot get the time value from column: 1
Cannot get time value in the result set.
java.sql.SQLException

Anyone know why?

Why don't you use the expression system of birt.
first recover your minutes and after do a difference.

row["YourDate"].getTime()

;-)

Yeeesss....I suppose I could...
But it still doesn't explain why it doesn't work.

This gives the same error:

select sec_to_time(unix_timestamp('2006-02-24 10:59:31') -
unix_timestamp('2006-02-24 09:59:30'))
as elapsed

And it shouldn't. I think there may be a bug?
