PHP MYSQL 查询组合并添加两个相等的结果

Question

有人请帮我解决我已经花了两天时间的 sql 查询....

我有下面给出的 MYSQL 查询

(SELECT
  c.cl_list as cl_list,
  c.name as name,
  pc.value as value,
  count( pc.value) as total
FROM
  projs p 
  LEFT JOIN classify_proj_new pc 
    ON p.proj_id = pc.proj_id_fk
  LEFT JOIN classify_list c 
    ON c.cl_list = pc.class_id_fk
WHERE
  MATCH ( p.title ) AGAINST ( 'jerm'  IN BOOLEAN MODE )
GROUP BY 
  c.cl_list,
  pc.value)
UNION ALL
(SELECT
  c.cl_list as cl_list,
  c.name as name,
  pc.value as value,
  count( pc.value) as total
FROM
  jerm p 
  LEFT JOIN classify_jerm_new pc
    ON p.jerm_id = pc.jerm_id_fk
  LEFT JOIN classify_list c
    ON c.cl_list = pc.class_id_fk
WHERE
  MATCH ( p.jermname ) AGAINST ( 'jerm'  IN BOOLEAN MODE )
GROUP BY
  c.cl_list,
  pc.value)

给出的结果(如下):

  cl_list      name              value        total
------------------------------------------------------------------------------------
    1       department         jewller          2
    3       price                 50            2
    6       color                blue           1
    6       color                Red            2
    1       department         jewller          1
    6       color                Red            1

但我正在尝试获得一个结果，该结果可以添加重复值的总数并避免重复值....类似这样的事情(如下):

  cl_list      name              value        total
------------------------------------------------------------------------------------
    1       department         jewller          3
    3       price                 50            2
    6       color                blue           1
    6       color                Red            3

有人请帮助我，我对我的输出感到非常难过......

非常感谢您...

从您的查询中选择并按 cl_list、名称和值分组:

SELECT
  cl_list,
  name,
  value,
  sum(total) as total
FROM (
  -- your current query here ...
) data
GROUP BY
  cl_list,
  name,
  value
