Since the recent thread with Innodb table space, I

Hi,
This is the free space left in the InnoDB file. InnoDB will claim all the
space that it is configured for and if autoextend is turned on it will use
additional space when needed until the file limit is reached.

Hi all,
Does MySQL support fetch-on-demand of resultsets?
And if so, does it support multiple cursors fetching on the same time
using the same connection?
If so, is it thread safe?
With regards,

If it were all in one row, you may be able to compare datetime fields.
I do not know if you can do this with 2 rows, and the query will probably
be rough.
Did you design the table? Can you create it so that your row has start and
stop times, instead of creating another row?

It would help if you would say how many entries do you have for changed =0

Since changed is a timestamp you should never get an entry of 0. So the
