select cast(COL1 as datetime) from TABLE where COL1<>'' and isdate(COL1) =1 and
cast(COL1 as datetime) < (DATEADD(YY, -3, GETDATE()))

above query gives the error
Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type datetime.

COL1 is an nvarchar column

Any idea why?

Definitely something to do with the kind of data you have inside the table. Could you provide some of the data inside the table Table for COL1 ?

08/17/2009 in mm/dd/yyyy format. If you see the query, i filter out invalid dates, which are nulls, blanks etc

You have something in there that can't be cast as a datetime and it is failing. Your where clause also casts Col1 as a datetime so if there is something in the table it will throw an exception.
