DateTime types and getdate() comparison

SQL 2000. Let's say column MyDate is a datetime type. Is this
comparison syntax OK as is?
... where MyDate <= getdate()
Or is some formatting of the column value and/or of the function's
return value required for the comparison to work?
Thanks
LiamComparison operators (<,>,=, <>, >=, <= ) are allowed between two values wit
h
a datatype of datetime. Your expression is fine.
However, if you want to do things like add or subtract datetime values, you
will need to use the date and time functions in SQL Server.

but don't convert the column - you'll lose any sargability if it's indexed.
i tend not to try to rely on date data having being inserted with a time
of midnight, so i convert the variable and perform range queries
if you need mydate <= just the date: then do
MyDate < tomorrow at midnight
e.g.
where MyDate < dateadd(day, datediff(day, 0, getdate()), 0)+1
or if you need MyDate for just today
where MyDate >= dateadd(day, datediff(day, 0, getdate()), 0)
and MyDate < dateadd(day, datediff(day, 0, getdate()), 0)+1
or if you need mydate <= current date and time, then simply using
getdate() is appropriate.
