      --source plugin/spider/spider/include/init_spider.inc
       
      SET spider_same_server_link= on;
      eval create server s foreign data wrapper mysql options (host "127.0.0.1", database "test", user "root", port $MASTER_MYPORT);
       
      CREATE TABLE t (a INT);
      CREATE TABLE t_spider (a INT) ENGINE=SPIDER COMMENT = "wrapper 'mysql', srv 's', table 't'" CHARSET utf32;
      SELECT * FROM t_spider;
       
      # Cleanup
       
      DROP TABLE t_spider, t;
      DROP SERVER s;

      mysqltest: At line 8: query 'SELECT * FROM t_spider' failed: 1231: Variable 'character_set_client' can't be set to the value of 'utf32'
      

      At this point Spider tries to run SET NAMES utf32 (hopelessly of course).

      Note that the test case sets an explicit character set for the Spider table for simplicity; in reality, it would rather be either a database charset, or a system-wide character-set-server. The result is the same anyway.
