    Description

      It looks like that, the db server could not query if the value has a dash "-" inside, as far as I know, the affected charset is armscii8.

      For more see the repo command as below, and the db dump is attached:

      MariaDB [bugtest]> create table test(columnname varchar(64) CHARACTER SET armscii8);
      Query OK, 0 rows affected (0.07 sec)
       
      MariaDB [bugtest]> insert into test values ('abc-def');
      Query OK, 1 row affected (0.04 sec)
       
      MariaDB [bugtest]> select * from test where columnname = 'abc-def';
      Empty set (0.00 sec)
       
      MariaDB [bugtest]> select * from test where columnname like 'abc%';
      +------------+
      | columnname |
      +------------+
      | abc-def    |
      +------------+
      1 row in set (0.00 sec)
