Answer 1

This should work absolutely fine.

select substring_index(substring_index('Viewpoint Vancouver, 1200 West 73rd Avenue Suite 606, Vancouver, British Columbia, V6P 6G5',',', -2),',',1)

Check out the documentation for Substring Index here - https://dev.mysql.com/doc/refman/8.0/en/string-functions.html#function_substring-index

Answer 2

I recomment the solution by MontyPython, but would like to add a regular expression solution. MySQL supports regular expressions starting from version 8 , MariaDB has it since version 10.0.5 . Here's an example for MariaDB:

SELECT REGEXP_REPLACE('...', '.*,(.*),', '\\1');

Example:

MariaDB [(none)]> select REGEXP_REPLACE('Viewpoint Vancouver, 1200 West 73rd Avenue Suite 606, Vancouver, British Columbia, V6P 6G5', '.*,(.*),.*', '\\1');
+-----------------------------------------------------------------------------------------------------------------------------------+
| REGEXP_REPLACE('Viewpoint Vancouver, 1200 West 73rd Avenue Suite 606, Vancouver, British Columbia, V6P 6G5', '.*,(.*),.*', '\\1') |
+-----------------------------------------------------------------------------------------------------------------------------------+
|  British Columbia                                                                                                                 |
