Help with a regular expression for UK Phone Numbers

I am having trouble getting a regular expression to work in mySQL. The expression came from http://regexlib.com/REDetails.aspx?regexp_id=593 but when I try and test it I get the following error:-

select count(*) from test.PHONE_NUMBERS where phone not regexp '^(((\+44\s?\d{4}|\(?0\d{4}\)?)\s?\d{3}\s?\d{3})|((\+44\s?\d{3}|\(?0\d{3}\)?)\s?\d{3}\s?\d{4})|((\+44\s?\d{2}|\(?0\d{2}\)?)\s?\d{4}\s?\d{4}))(\s?\#(\d{4}|\d{3}))?$';
ERROR 1139 (42000): Got error 'repetition-operator operand invalid' from regexp

Any ideas?

That looks like a perl regexp, and mysql regexps are a little different.  See http://dev.mysql.com/doc/refman/5.0/en/regexp.html

\+ is intended to be the literal '+' character.  Mysql needs to see \\+ to get this right, because it does backslash escapes before it starts parsing the regexp.

\+ -> \\+

Same with \# and \( and \)

\# -> \\#
\( -> \\(
\) -> \\)

\d is intended to be a digit, and mysql doesn't support this method.  Use [0-9] instead.

\d -> [0-9]

\s is whitespace, not supported by mysql.  Use [[:space:]]

\s -> [[:space:]]

I think that covers all the dialect differences.  In the end the only backslashes present should be in the double-escaped literal (like \\#) patterns.
