Ah yeah, the concatenation. I was thinking of using "+" but I can't make it work and the documentation says not to use it for psycopg2.
Sorry what's bottom-post? I see you did that yesterday. Is there a format for before making a bottom-post?On Wed, May 16, 2018 at 11:04 AM, David G. Johnston <david.g.johnston@xxxxxxxxx> wrote:

It does what I want it to do but I am not sure if that's always the case if pattern param is empty.Sorry for bumping this email.I would just like to clarify regarding regexp_replace:
WHEN mobilenumber ~'^9[0-9]' AND LENGTH(mobilenumber) = 10
THEN regexp_replace(mobilenumber, '', '+63')If you could bottom-post like the rest of us that would be helpful.While that seems to work it is definitely obscure. You should just use concatenation.’+63' || mobilenumberThe pattern is a zero-length string, matched once, which first matches the start of the input text. Not sure what happens when the input is the empty string...David J.
