Bug 10185: Fix update 3.09.00.025
It can remove all reserves from reserves table when there is no entries in old_reserves. This is due to @ai which is set to NULL in SET @ai = ( SELECT MAX( reserve_id ) FROM tmp_reserves ) and reserve_id > NULL returns no results in INSERT INTO reserves SELECT * FROM tmp_reserves WHERE reserve_id > @ai Signed-off-by: Kyle M Hall <kyle@bywatersolutions.com> Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de> Test plan and comments on second patch.
