Hi,

I have a fairly weird 'bug' with a simple query, and I vaguely remember reading the reason for it somewhere a long time ago but would love someone to refresh my memory.

The table is a basic ID, Datetime table.

The query is:

select ID, Datetime from Table where Datetime <= '2010-03-31 23:59:59'

The problem is that the query results include results where the Datetime is '2010-04-01 00:00:00'. The next day. Which it shouldn't.

Anyone?

Cheers

Moo
