It looks to me like your "fromdate" field might be char/varchar instead of datetime. In that case, you'll get any string that starts with a character > "2" in the example you gave.

If the column is datetime, try casting the date in the where clause as datetime.

If the column is char/varchar, you probably need to cast both as datetime, or you need to modify the table so the column is datetime (if that won't break anything else in the database/app/data connection layer). Casting both will result in a slow query (since it'll have functions on both sides of the equation), but will at least work.
