无论如何，我是否可以从两个 MySQL 查询创建 Drupal 视图。我想创建事件视图，一个 MySQL 查询用于带来已经开始和尚未完成的事件，另一个查询用于显示事件还没有开始，一共展示了3个项目。

这是我要从中创建视图的两个 SQL 查询：

    SELECT f.delta      AS field_data_field_session_start_date_delta
     , f.entity_id  AS date_id_date_filter
     , f.delta      AS date_delta_date_filter
     , n.title      AS node_title
     , n.nid        AS nid
     , n.language   AS node_language
     , f.field_session_start_date_value AS field_data_field_session_start_date_field_session_start_date
     , f.field_session_start_date_value2 AS field_data_field_session_start_date_field_session_start_date2
     , 'node'       AS field_data_field_session_start_date_node_entity_type
  FROM `node` n
  JOIN `field_data_field_session_start_date` f
    ON f.entity_id = n.nid
   AND f.entity_type = 'node'
   AND f.deleted = '0'
   AND f.field_session_start_date_value >= NOW()
WHERE n.status = '1'
ORDER
    BY f.field_session_start_date_value ASC
LIMIT 3 OFFSET 0


SELECT f.delta      AS field_data_field_session_start_date_delta
     , f.entity_id  AS date_id_date_filter
     , f.delta      AS date_delta_date_filter
     , n.title      AS node_title
     , n.nid        AS nid
     , n.language   AS node_language
     , f.field_session_start_date_value AS field_data_field_session_start_date_field_session_start_date
     , f.field_session_start_date_value2 AS field_data_field_session_start_date_field_session_start_date2
     , 'node'       AS field_data_field_session_start_date_node_entity_type
  FROM `node` n
  JOIN `field_data_field_session_start_date` f
    ON f.entity_id = n.nid
   AND f.entity_type = 'node'
   AND f.deleted = '0'
   AND f.field_session_start_date_value <= NOW()
   AND f.field_session_start_date_value2 > NOW()
WHERE n.status = '1'
ORDER
    BY f.field_session_start_date_value ASC
LIMIT 3 OFFSET 0

我假设您知道如何从原始 sql 创建 Drupal 视图 - 即，只是其中一个查询。

您可以使用 UNION 命令创建 1 个返回两个查询结果的查询（在您的情况下，将两个查询括在括号中以确保 ORDER BY 和 LIMIT 与内部查询相关联）：

(SELECT f.delta      AS field_data_field_session_start_date_delta
     , f.entity_id  AS date_id_date_filter
     , f.delta      AS date_delta_date_filter
     , n.title      AS node_title
     , n.nid        AS nid
     , n.language   AS node_language
     , f.field_session_start_date_value AS field_data_field_session_start_date_field_session_start_date
     , f.field_session_start_date_value2 AS field_data_field_session_start_date_field_session_start_date2
     , 'node'       AS field_data_field_session_start_date_node_entity_type
  FROM `node` n
  JOIN `field_data_field_session_start_date` f
    ON f.entity_id = n.nid
   AND f.entity_type = 'node'
   AND f.deleted = '0'
   AND f.field_session_start_date_value >= NOW()
WHERE n.status = '1'
ORDER
    BY f.field_session_start_date_value ASC
LIMIT 3 OFFSET 0)
UNION
(SELECT f.delta      AS field_data_field_session_start_date_delta
     , f.entity_id  AS date_id_date_filter
     , f.delta      AS date_delta_date_filter
     , n.title      AS node_title
     , n.nid        AS nid
     , n.language   AS node_language
     , f.field_session_start_date_value AS field_data_field_session_start_date_field_session_start_date
     , f.field_session_start_date_value2 AS field_data_field_session_start_date_field_session_start_date2
     , 'node'       AS field_data_field_session_start_date_node_entity_type
  FROM `node` n
  JOIN `field_data_field_session_start_date` f
    ON f.entity_id = n.nid
   AND f.entity_type = 'node'
   AND f.deleted = '0'
   AND f.field_session_start_date_value <= NOW()
   AND f.field_session_start_date_value2 > NOW()
WHERE n.status = '1'
ORDER
    BY f.field_session_start_date_value ASC
LIMIT 3 OFFSET 0)
