Question

我是否有从两个MySQL查询创建Drupal视图。我想创建一个事件视图，一个MySQL查询用于引发已启动但尚未完成的事件，另一个查询是调出事件还没有开始，总共显示3个项目。

以下是我想要创建视图的两个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命令创建一个返回两个查询结果的查询（在您的情况下，将两个查询都括在括号中以确保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)

无论如何，我从sql查询创建一个Drupal视图
