MySql中的正则表达式替换选择查询

I have this SQL query:

SELECT * FROM pages WHERE page_title = 'paul_mccartney'

But often in page_title the value is like 'paul_mccartney (musician)'. And in this case I get NULL back. I had the idea to regex replace everything which is between ( and ) including the ():

SELECT * FROM pages WHERE REPLACE(REGEXP('/\([^\*].*\)/U'), '', page_title) = 'paul_mccartney'

But it doesn't work. Is my idea possible or not? And how?

    Although your question is about using RegEx but have you looked into MySQL fulltext search functions?

    https://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html https://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html

    Using the following tutorials if you have a row that is like this:

    Id  title
    1   paul_mccartney (musician)
    

    Using the example SQL provided will return a result:

    SELECT * FROM articles
    WHERE MATCH (title) AGAINST ('paul_mccartney' IN BOOLEAN MODE)
