Details

    Description

      From https://stackoverflow.com/questions/76985048/triggers-not-working-as-expected-for-set-columns-in-mariadb:

      Simplified version:

      CREATE TABLE t1 ( m set('sms') NOT NULL);
      		 
      CREATE TABLE t2 (i int);
      		 
      CREATE TABLE u (i int);
      		 
       create or replace trigger t1 AFTER INSERT ON t1 FOR EACH ROW INSERT IGNORE INTO t2 SELECT u.i from u JOIN (SELECT 'sms' AS method) m ON FIND_IN_SET(m.method, NEW.m);
      		 
      insert into t1 values ('sms');
      		 
      ERROR 1054 (42S22): Unknown column 'm' in 'field list'

      Requires the NEW.m reference to be in the JOIN ON criteria.
