SQL Date

I have got two datetime columns from two seperate tables.

table 1:- 2006-12-07 00:00:00.000
table 2:- 2006-12-07 12:41:00.000

i want to join them together, so how do i cast table 2 column as 2006-12-07 00:00:00.000

I tend to do it by truncating the time portion:

-- UK setup in SQL
select cast(convert(nvarchar(10), mydatecolumn, 103) as datetime) from mytable

-- US setup in SQL
select cast(convert(nvarchar(10), mydatecolumn, 101) as datetime) from mytable

If you are on 2008 or later

join table2
on convert(date, table1.datefield) = convert(date, table2.datefield)

Select Dateadd(day, datediff(day, 0, getdate()), 0 )

is strictly more correct than Leo's post above, although Leo's post will work for days but no other datetime type.
