    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a VARCHAR(32) CHARACTER SET latin1) ENGINE=InnoDB;
      		 
      INSERT INTO t1 VALUES ('A'),('A ');
      		 
      SELECT QUOTE(a) FROM t1 ORDER BY a, BINARY(a) DESC;


      +----------+
      		 
      | QUOTE(a) |
      		 
      +----------+
      		 
      | 'A '     |
      		 
      | 'A'      |
      		 
      +----------+


      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a VARCHAR(32) CHARACTER SET latin1) ENGINE=ColumnStore;
      		 
      INSERT INTO t1 VALUES ('A'),('A ');
      		 
      SELECT QUOTE(a) FROM t1 ORDER BY a, BINARY(a) DESC;


      +----------+
      		 
      | QUOTE(a) |
      		 
      +----------+
      		 
      | 'A'      |
      		 
      | 'A '     |
      		 
      +----------+

      Notice, ColumnStore returns the two records in reverse order.
