      Description

      The following query is fine :

      SELECT 
        R.splitlot_id,
        R.run_id, 
        I.ptest_info_id,
        COLUMN_GET(R.dynamic_flags,I.ptest_info_id as CHAR(1)),
        COLUMN_GET(R.dynamic_value,I.ptest_info_id as DECIMAL ) 
      FROM  
        wt_ptest_results_rows R INNER JOIN
        wt_ptest_info I on R.splitlot_id=I.splitlot_id
      where 
        COLUMN_GET(R.dynamic_value,I.ptest_info_id as DECIMAL) IS NOT NULL;

      but

      CREATE VIEW `wt_ptest_results_view`
      (splitlot_id,run_id,ptest_info_id,flags,value) AS 
      SELECT 
        R.splitlot_id,
        R.run_id, 
        I.ptest_info_id,
        COLUMN_GET(R.dynamic_flags,I.ptest_info_id as CHAR(1)),
        COLUMN_GET(R.dynamic_value,I.ptest_info_id as DECIMAL ) 
      FROM  
        wt_ptest_results_rows R INNER JOIN
        wt_ptest_info I on R.splitlot_id=I.splitlot_id
      where 
        COLUMN_GET(R.dynamic_value,I.ptest_info_id as DECIMAL) IS NOT NULL;
       
      select * from wt_ptest_results_view limit 1;

      show create view wt_ptest_results_view;

      Here is an simplified version of the tables in the test :

      CREATE TABLE `wt_ptest_info` (
        `splitlot_id` int(10) unsigned NOT NULL DEFAULT '0',
        `ptest_info_id` smallint(5) unsigned NOT NULL DEFAULT '0',
        KEY `wtptestinfo_splitlot_ptest` (`splitlot_id`,`ptest_info_id`)
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 PACK_KEYS=1
       
       
      CREATE TABLE `wt_ptest_results_rows` (
        `splitlot_id` int(10) unsigned NOT NULL DEFAULT '0',
        `run_id` mediumint(7) unsigned NOT NULL DEFAULT '0',
        `dynamic_flags` blob,
        `dynamic_value` blob,
        PRIMARY KEY (`splitlot_id`,`run_id`)
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1
