Answer 1

您好，您需要设置toIndex:-1      var sqlParam = new SuperMap.GetFeaturesBySQLParameters({
            queryParameter: {
                name: "Countries@World",
                //attributeFilter: "SMID = 247"
            },
            datasetNames: ["World:Countries"],
            toIndex:-1
        });
