What is the correct syntax for a Regex find-and-replace using REGEXP_REPLACE in MariaDB?

Question

I need to run a regex find-and-replace against a column named message in a MySQL table named post.

My database is running MariaDB 10.

Answer 1

You have to do a lot of escaping here:

REGEXP_REPLACE(message, "\\[quote\\sauthor=(.+)\\slink=[^\\]]+]", "\\[quote=\"\\1\"\\]")

Please note that you have to reference the Group by \\1
