Hi,
Could someone explain the following behaviour?
SELECT regexp_replace(E'Hello & goodbye ',E'([&])','&#' ||
ascii(E'\\1') || E';\\1');
This returns:
regexp_replace
------------------------
Hello \& goodbye
(1 row)
So it matched:
SELECT chr(92);
chr
-----
\
(1 row)
But notice that when I append the value it's supposed to have matched
to the end of the replacement value, it shows it should be '&'.
Just to confirm:
SELECT ascii('&');
ascii
-------
38
(1 row)
So I'd expect the output of the original statement to be:
regexp_replace
------------------------
Hello && goodbye
(1 row)
What am I missing?
