SELECT concat('', COLUMN_NAME, ' != null"> ', COLUMN_NAME, ',')  FROM information_schema.COLUMNS
WHERE TABLE_NAME = 'view_opportunity' AND TABLE_SCHEMA = 'helenbergh_mcrm_pro';

SELECT concat('', COLUMN_NAME, ' != null"> #{', COLUMN_NAME, '},')  FROM information_schema.COLUMNS
WHERE TABLE_NAME = 'view_opportunity' AND TABLE_SCHEMA = 'helenbergh_mcrm_pro';

SELECT concat('', COLUMN_NAME, ' != null"> ', COLUMN_NAME, ' = #{', COLUMN_NAME, '},')  FROM information_schema.COLUMNS
WHERE TABLE_NAME = 'view_opportunity' AND TABLE_SCHEMA = 'helenbergh_mcrm_pro';

SELECT concat('private ',
              CASE
