After updating from 2.3.1. to 2.6.4
Error is received from PDO when (column) field name contains '&' sign.
Fatal error: Uncaught PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'test_list.a`&`b_sign' in 'field list' in ...../vendor/zendframework/zend-db/src/Adapter/Driver/Pdo/Connection.php on line 360
Even though column is not listed in $crud->column(), callback or any other code.
Regards,
Marty
