Hi,
How can I remove characters that form a part of regular expressions? I
would like to remove all instances of the following characters:
[
]
\
+
Given that these all mean something in regexp, I am trying to prefix
them with a backslash, but it doesn't work. I tried the following:
update TABLE
set COLUMN = regexp_replace(COLUMN, E'[\\\[\]\+]+', '')
;
This did not work so I tried the naked characters separated by a pipe,
as follows:
update TABLE
set COLUMN= regexp_replace(COLUMN, E'[\|[|]|+]+', '')
;
But this of course did not work either. I've read and re-read the
pattern matching doc page ( http://snipurl.com/pg_regexp ) but it
doesn't seem to offer much help.
Any thoughts on what I am doing wrong?
