Question

我有这个问题：

select
  departments.id as id,
  departments.active as active,
  departments.origin as origin,
  TIMESTAMPDIFF (YEAR, origin, CURDATE()) as duration,
  CONCAT (departments.name, ' ', departments.section) as name,
  GROUP_CONCAT(persons.name SEPARATOR ', ') as persons,
  CONCAT (units.type, ' - ', units.name) as unit
from `departments`
  inner join `units` on `departments`.`unit_id` = `units`.`id`
  left join `department_person` on `departments`.`id` = `department_person`.`department_id`
  left join `persons` on `department_person`.`person_id` = `persons`.`id`
where ((departments.id like '%search%')
       or (CONCAT (departments.name, ' ', departments.section) like '%search%')
       or (TIMESTAMPDIFF (YEAR, origin, CURDATE()) like '%search%')
       or (CONCAT (units.type, ' - ', units.name) like '%search%')
       or (LOWER(`departments`.`active`) LIKE '%search%')
)
group by `departments`.`id`
having GROUP_CONCAT(persons.name SEPARATOR ', ') LIKE '%search%'
order by `id` asc
limit 10
offset 0

我想在所有选定的字段中执行搜索：ID，活动，来源，持续时间，姓名，单位和人。一切正常，除非我在人员中添加having GROUP_CONCAT(persons.name SEPARATOR ', ') LIKE '%search'子句进行搜索。然后，没有任何回报...

您能告诉我如何修改查询以便我可以在人员，group_concat字段内进行搜索吗？提前谢谢。

使用＆＃39; group_concat＆＃39;进行MySQL搜索字段和＆＃39;条款
