      Description

      Here is the repro:

      delimiter //

      drop function if exists func5073//
      CREATE FUNCTION func5073(arg ENUM('a', 'b')) RETURNS ENUM('c', 'd') DETERMINISTIC
      BEGIN
      RETURN arg;
      END//

      delimiter ;
      SELECT func5073(1);

      This is what happens on the MariaDB client

      MariaDB [test]> SELECT func5073(1);
      ERROR 1265 (01000): Data truncated for column 'func5073(1)' at row 1
      MariaDB [test]> SELECT version();
      +----------------+
      | version()      |
      +----------------+
      | 10.6.9-MariaDB |
      +----------------+
      

      We get an error about our silly stored function.

      Here is what the python connector does:

      import mariadb
      import mariadb.constants.CLIENT as CLIENT
       
      dut_cfg = {"host": "vqc004a", "port": 60190,
                  "user": "root", "passwd": "",
                  "db": "test", "autocommit": True,
                  "connect_timeout": 60,
                  "client_flag": CLIENT.MULTI_STATEMENTS}
       
      conn = mariadb.connect(**dut_cfg)
      dut_cur = conn.cursor()
       
      sql0="SELECT func5073(1)"
       
      for cursor in (dut_cur, ):
          cursor.execute(sql0)
          print(cursor.fetchall())
      

      Let's run this.

      [root@vqc004a 5073]# python foo.py
      []
      [root@vqc004a 5073]#
      

      There isn't any exception that is raised. I expected a mariadb.DataError exception to be raised.
