If the pattern is empty '', does this mean that the replacement_string param will be added to the value of source? 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' || mobilenumber
The 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...
