Question

我想在Google地图上突出显示多个国家/地区，但我对此查询有点困惑。它可以在一个国家/地区运行，例如，如果我强调墨西哥它有效，但是当尝试突出墨西哥和印度时它不起作用。

我已经尝试过以下代码，但它无效

layer = new google.maps.FusionTablesLayer({
  query: {select: "kml_4326", 
          from: tableid,
          where: "name_0 = 'Mexico' and name_0 = 'India'"},
  styles: [{
  polygonOptions: {
    strokeWeight: "0",
    //strokeColor: "#FF0000",
    strokeOpacity: "0.4",
    fillOpacity: "2",
    fillColor: "#FF0000"

  }
}]});

该代码适用于单个国家/地区。

layer = new google.maps.FusionTablesLayer({
  query: {select: "kml_4326", 
          from: tableid,
          where: "name_0 = 'Mexico'"},
  styles: [{
  polygonOptions: {
    strokeWeight: "0",
    //strokeColor: "#FF0000",
    strokeOpacity: "0.4",
    fillOpacity: "2",
    fillColor: "#FF0000"

  }
}]});

此外，我已尝试将以下代码作为Google Developers的Google文档引用，但它会突出显示整个地图。

layer = new google.maps.FusionTablesLayer({
    query: {
      select: 'kml_4326',
      from: tableid
    },
    styles: [{
      polygonOptions: {
        //fillColor: '#00FF00',
       // fillOpacity: 0.3
      }
    }, {
      where: 'name_0 == India',
      polygonOptions: {
        fillColor: '#000'
      }
    }, {
      where: 'name_0 == Mexico',
      polygonOptions: {
        fillOpacity: 1.0,
        fillColor: '#00FF00'
      }
    }]
  });

  layer.setMap(map);

尝试将select语句更改为：

query: {select: "kml_4326", 
          from: tableid,
          where: "name_0 IN ('Mexico','India')"
       },
