Question

我的查询：

 SELECT ID, assiduos_a1, assiduos_a2, max(date)
   FROM cli_agendados_assiduos
  WHERE ID = 10357410;

哪个returns:

id          assiduos_a1 assiduos_a2 max(date)
10357410    337         508         08/01/2015 14:54:48

但我需要行中的结果，如下所示：

Label       Value   id          max(date)
assiduos_a1 337     10357410    08/01/2015 14:54
assiduos_a2 508     10357410    08/01/2015 14:54

只有在这种格式下我的图表（饼图google）才能正常工作！

Answer 1

您可以使用 union all:

SELECT 'assiduos_a1', assiduos_a1 as value, id, max(date)
FROM cli_agendados_assiduos
WHERE ID = 10357410
UNION ALL
SELECT 'assiduos_a2', assiduos_a2 as value, id, max(date)
FROM cli_agendados_assiduos
WHERE ID = 10357410;
