Hi,
I tried to order a text-column only by parts of the entries. Therefore I used
regexp_matches(), but unfortunately I am loosing rows.
SELECT regexp_matches('abc','[0-9]+'), regexp_matches('123','[0-9]+');
Does not return "{null}, {123}" but no result at all.
Is this behavior expected? How can I work around?
I am running postgres 8.4
Andreas
