SQL convert string to date format 112

I have an input date and I need to convert it to format 112 (yyyymmdd) for use later on in my SQL statement.

declare @day varchar(10)

set @day = '6/21/2013'

select @day

I've done this before...IDK if it's because I'm on SQL 2000 for this project that it's not working now.

Solution

I would convert it to a datetime first, then to the format that you want:

declare @day varchar(10)

set @day = '6/21/2013'

select convert(varchar(10), cast(@day as datetime), 112);
