MySQL REGEXP不匹配

Question

I have a regular expression intended to catch phone numbers within a string

/[1,+ ().-][\s.-]\d{3}[\s.-]\d{3}[\s.-]\d{4}/

I try to query my MySql database for this regex using this query:

SELECT
    *
FROM
    `everything`.`instances_meta` AS m
WHERE
    `meta.value` REGEXP "[1,+][\s.-]\d{3}[\s.-]\d{3}[\s.-]\d{4}" 

I can confirm the regex, itself, does what I want from testing it here but it does not pull any matches when queried. Something tells me I am missing some sort of expression to say "anywhere in the string". I would specify the regex engine but I am unsure of what MySql uses.

Answer 1

Use

"[1,+][[:blank:].-][0-9]{3}[[:blank:].-][0-9]{3}[[:blank:].-][0-9]{4}"

as MySQL REGEXP does not support \\s and \\d .

The [:blank:] matches spaces and tabs, and [0-9] matches any ASCII digit.
