    Description

      Oracle does not require derived tables to have aliases:

      SQL> SELECT * FROM (SELECT * FROM t1) WHERE a=20;
      		 
       
      		 
      	 A
      		 
      ----------
      		 
      	20

      MariaDB returns an error for the same query:

      MariaDB [test]> SELECT * FROM (SELECT * FROM t1) WHERE a=20;
      		 
      ERROR 1248 (42000): Every derived table must have its own alias

      When running in sql_mode=ORACLE, we'll allow derived tables not to have aliases.
