Hi all,

Doing some googling and looking through the docs, I can't find an
obvious way to do this beside post processing after the query (which I
am trying to avoid).

I'm trying to select a list of names in alphabetical order but
ignoring the whitespace.

So for example, the name "La Combe" should come after "Lace" but
before "Lacs..."


Any ideas?

Mikel

Could you do it like this:

SELECT
        replace(name_column, ' ', '') AS name_replaced
FROM
        your_table_name
ORDER BY
        name_replaced

This can get a bit slowish if your table has quite a number of rows.

FWIW, this would probably happen automatically if you were using a
non-C locale.  I'm not sure that's really a good solution, because
switching to a different locale would affect every sort operation
you ever do.  But it's an alternative to consider.
