调整正则表达式以与MySQL一起使用 [英] Adapting a Regex to work with MySQL

问题描述

我拥有的这个Regex在所有测试中都可以正常工作，但是尽管我一直在使用Google谷歌搜索并尝试其变形示例，但我无法使其在MySQL中正常工作.

I've got this Regex that works fine in all my testing, but I am unable to make it work in MySQL, despite the examples that I've been googling and trying variations of this:

^[A-Za-z]{2,4}-\d{3}-\d{2}$

在Javascript中，它可以正确匹配AA-001-01至ZZZZ-999-99，因此在MySQL中尝试了对正则表达式进行各种调整，但都没有运气:

In Javascript, it correctly matches AA-001-01 through ZZZZ-999-99, and so have tried it in MySQL with various tweaks to the regex, all with no luck:

SELECT * FROM products WHERE sku REGEXP '^[A-Za-z]{2,4}-\d{3}-\d{2}$'

(该表包含数千条记录，其中sku与上面给出的示例匹配)

(The table contains thousands of records where sku matches the samples given above)

据我所知，对Mysql Regex的支持是有限的，但是这应该不能正常工作，或者在使用Mysql时还需要考虑其他语法吗?

As best as i can tell, Mysql Regex support is limited, but should this not work properly, or is there some further syntax consideration to work with Mysql?

推荐答案

要匹配数字，应使用[0-9]或[[:digit:]].

To match a digit you should use either [0-9] or [[:digit:]].

尝试一下:

SELECT col1, col2, ..., coln
FROM products
WHERE sku REGEXP '^[A-Za-z]{2,4}-[0-9]{3}-[0-9]{2}$'
