当我想限制它时,我的地图会显示融合表中的所有数据。
另外,我如何通过“地理名称”进行查询。领域?我尝试了下面的查询,但它不起作用。
***编辑我使用类似的代码解决了下面的问题:
select: 'State Abbr.',
from: '1xdysxZ94uUFIit9eXmnw1fYc6VcQiXhceFd_CVKa',
where: "'State Abbr.' = 'FL'",
问题在于缺乏报价。
感谢任何帮助!
select: 'State-County',
from: '1xdysxZ94uUFIit9eXmnw1fYc6VcQiXhceFd_CVKa',
where: 'State-County = AL-Autauga'
这是我目前的代码:
****编辑:我已通过更新代码修复了以下问题,如下所示
查询:{ 选择:' GEO_ID', 来自:' 1xdysxZ94uUFIit9eXmnw1fYc6VcQiXhceFd_CVKa', 其中:" GEO_ID =' 05000US01001'" },
