Concat in a where clause

I'm writing an SQL statement where I have to concatenate year, month, and day so I can check for a date range. This is what I have so far:

where YR||MM||DD between 20050701 and 20060630,

but it returns no row. If I comment it out and just use "where YR = 2005", I get lots of rows returned. Why doesn't this work?
