    Ah, ChrisM@Work, I think I get what you were saying now.

    and LEN(LTRIM(RTRIM(CURRENT_POINT))) > 0

    Seems to have fixed it.

    Thanks all!

    LEN ignores leading spaces, you don't need to trim. However, Steve's suggestion is likely to perform faster because CURRENT_POINT isn't wrapped in a function, which in most cases would prevent an index on CURRENT_POINT from being used for the filter.
