mysql - Having子句后如何使用GROUP BY Mysql

Question

这是获取特定用户帐户的查询，产品与帐户相关一对多关系，因此每个产品有四个权限

所有未被Disable 并显示其权限的帐户 我根据场景获得了所有帐户，但问题是如果一个帐户有不止一种产品，那么它显然多次显示帐户 ID

*我正在寻找 GROUP BY a.id 在检查权限的 HAVING 子句之后 * 但没有运气得到语法错误

Error Code: 1064 right syntax to use near 'GROUP BY a.`id` LIMIT 0, 1000' at line 14

这是我的问题

SELECT  a.`id` AS aid,ap.`pid`, p.`products_name`, a.accounts_account_number, c.clients_name,a.accounts_product_type AS pptype,
c.`clients_last_name`, a.`accounts_account_name`
,(SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Readonly' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Readonly,
(SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Buy' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Buy,
(SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Sell' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Sell,
(SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Disable' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS `Disable`
 FROM `bf_clients` c INNER JOIN `bf_user_clients` uc ON (c.`id` = uc.`client_id`)
 INNER JOIN `bf_accounts` a ON (c.`id` = a.`accounts_clients`)
 INNER JOIN `bf_account_products` ap ON (a.`id` = ap.`aid`)
 INNER JOIN `bf_products` p ON (ap.`pid` = p.`id`)
 WHERE uc.`agt_user_id`=2 AND a.deleted=0 AND c.deleted=0                
 HAVING (Readonly !='' OR Buy !=''  OR Sell !=''  OR `Disable` !='' ) 
 AND `Disable` !='1'   ORDER BY a.`id`  GROUP BY a.`id`

任何帮助将不胜感激

你可以尝试使用外层选择

SELECT q.*
  FROM
(
  SELECT a.`id` AS aid,ap.`pid`, p.`products_name`, a.accounts_account_number, c.clients_name,a.accounts_product_type AS pptype,
         c.`clients_last_name`, a.`accounts_account_name`,
         (SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Readonly' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Readonly,
         (SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Buy' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Buy,
         (SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Sell' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS Sell,
         (SELECT `status` FROM `bf_account_permissions` WHERE `permission`='Disable' AND uid=2 AND aid=a.id AND pid=ap.`pid`) AS `Disable`
    FROM `bf_clients` c INNER JOIN `bf_user_clients` uc ON (c.`id` = uc.`client_id`)
   INNER JOIN `bf_accounts` a ON (c.`id` = a.`accounts_clients`)
   INNER JOIN `bf_account_products` ap ON (a.`id` = ap.`aid`)
   INNER JOIN `bf_products` p ON (ap.`pid` = p.`id`)
   WHERE uc.`agt_user_id`=2 AND a.deleted=0 AND c.deleted=0                
  HAVING (Readonly !='' OR Buy !=''  OR Sell !=''  OR `Disable` !='' ) AND `Disable` !='1'   
) q
 GROUP BY aid
