      Description

      --source include/have_partition.inc
       
      INSTALL SONAME 'ha_spider';
      SET spider_same_server_link= 1;
       
      CREATE TABLE t1 (a INT PRIMARY KEY);
      CREATE TABLE t2 (a INT PRIMARY KEY);
       
      eval 
      CREATE TABLE t (a INT, PRIMARY KEY (a DESC)) ENGINE=SPIDER
      COMMENT "host '127.0.0.1', port '$MASTER_MYPORT', user 'root'"
      PARTITION BY RANGE (a) 
      (PARTITION p1 VALUES LESS THAN (4) COMMENT "table 't1'",
       PARTITION p2 VALUES LESS THAN (MAXVALUE) COMMENT "table 't2'");
       
      INSERT INTO t VALUES (1),(2),(10),(11);
      SELECT * FROM t WHERE a > 1 ORDER BY a;
      

      SELECT returns an empty result set.

      SELECT * FROM t WHERE a > 1 ORDER BY a;
      a
      

      With an ASC key the expected result is returned:

      SELECT * FROM t WHERE a > 1 ORDER BY a;
      a
      2
      10
      11
