错误1054 MySql for my Query

Question

我在MySql中运行以下查询

SELECT count(*) 
  FROM `pitches` AS `Pitch` 
        INNER JOIN `business_sectors_pitches` AS `BusinessSector` 
           ON (`BusinessSector`.`pitch_id` = `Pitch`.`id`) 
         LEFT JOIN `investments` AS `Investment` 
           ON (`Investment`.`pitch_id` = `Pitch`.`id`) 
         LEFT JOIN `users` AS `User` 
           ON (`Pitch`.`user_id` = `User`.`id`) 
         LEFT JOIN `loan_pitches` AS `LoanPitch` 
           ON (`LoanPitch`.`pitch_id` = `Pitch`.`id`) 
         LEFT JOIN `equity_pitches` AS `EquityPitch` 
           ON (`EquityPitch`.`pitch_id` = `Pitch`.`id`) 
 WHERE `Pitch`.`status` = 1 
   AND `Pitch`.`required_funding` >= 0 
   AND `Pitch`.`required_funding` <= 1500000 
 GROUP BY `Pitch`.`id` 
having ( (     sum(`Investment`.`amount`) / `Pitch`.`required_funding` >= 0 
           and sum(`Investment`.`amount`) / `Pitch`.`required_funding` <= 1
         )  or sum(`Investment`.`amount`) / `Pitch`.`required_funding` is null 
       )
       and count(`Investment`.`id`) >= 0 
       and count(`Investment`.`id`) <= 200 ;

并获得以下错误

ERROR 1054 (42S22): Unknown column 'Pitch.required_funding' in 'having clause'

我发现需要替换的地方，但我无法使其有效。

这段代码是从我的Cakephp代码生成的，但我不能让它在mysql客户端中运行。

根据@GolezTrol评论第二次尝试

SELECT count(*)    
FROM `pitches` AS `Pitch`          
INNER JOIN `business_sectors_pitches` AS `BusinessSector`             
  ON (`BusinessSector`.`pitch_id` = `Pitch`.`id`)           
LEFT JOIN `investments` AS `Investment`             
  ON (`Investment`.`pitch_id` = `Pitch`.`id`)           
LEFT JOIN `users` AS `User`             
  ON (`Pitch`.`user_id` = `User`.`id`)           
LEFT JOIN `loan_pitches` AS `LoanPitch`             
  ON (`LoanPitch`.`pitch_id` = `Pitch`.`id`)           
LEFT JOIN `equity_pitches` AS `EquityPitch`             
  ON (`EquityPitch`.`pitch_id` = `Pitch`.`id`)   
WHERE `Pitch`.`status` = 1     
  AND `Pitch`.`required_funding` >= 0     
  AND `Pitch`.`required_funding` <= 1500000 
  AND ( ((select sum(amount) from investments group by pitch_id)  / `Pitch`.`required_funding` >= 0             
  AND (select sum(amount)  from investments group by pitch_id) / `Pitch`.`required_funding` <= 1)  
  OR (select sum(amount)  from investments group by pitch_id) / `Pitch`.`required_funding` is null);
