默认情况下，Cassandra将以小写形式转换所有表/列名称。如果需要区分大小写的表/列名称，请用双引号将其括起来。使用desc table_name检查表格详细信息。

Eg:
Create table test(Column1 text primary key,"Column2" text);
 will result in cassandra table with 2 columns (column1 [Note all are lower case] and Column2 [C is uppercase])

这是更正脚本的示例。这里我的密钥空间名称是yupoint。

CREATE TABLE IF NOT EXISTS yupoint.user (
    id text,
    login text,
    password text,
    firstname text,
    lastname text,
    email text,
    activated boolean,
    lang_key text,
    activation_key text,
    reset_key text,
    reset_date timestamp,
    authorities set<text>,;
    PRIMARY KEY(id)
);

CREATE TABLE IF NOT EXISTS yupoint.user_by_login (
    login text,
    id text,
    PRIMARY KEY(login, id)
);

现在更改使用您的键区并创建一些记录。
使用yupoint；

yupoint>INSERT INTO user (id, login, password , firstname, lastname ,email ,activated ,lang_key, activation_key, authorities)
VALUES('3','admin','$2a$10$gSAhZrxMllrbgj/kkK9UceBPpChGWJA7SYIb1Mqo.n5aNLq1/oRrC','','Administrator','admin@localhost',true,'en','', {'ROLE_USER', 'ROLE_ADMIN'});

yupoint>INSERT INTO user_by_login (login, id)
VALUES('admin','3');

Cassandra中的所有标识符（表名、列名等）不区分大小写，除非每次引用它们时都将它们用引号括起来。DataStax documentation on this
因为这往往很繁琐，所以大多数人使用snake_case来命名表和列，如network_data和network_type。如果确实用引号括起来，这些标识符将继续出现在所有DESCRIBE输出中的引号中：

cqlsh:testdb> DESCRIBE TABLES;
table1  table2  network_data  "networkData"  table5

我已将您的查询调整为使用大写，并已在本地成功测试：

const createTable = (
  `CREATE TABLE IF NOT EXISTS testdb."networkData" (
    latitude DOUBLE, 
    longitude DOUBLE, 
    "allowsVoIP" BOOLEAN, 
    speed DOUBLE, 
    uuid TEXT, 
    timestamp TIMESTAMP PRIMARY KEY, 
    "networkType" TEXT, 
    "carrierName" TEXT, 
    altitude DOUBLE, 
    "macAddress" TEXT, 
    "publicIP" TEXT, 
    "ssidLabel" TEXT, 
    "networkInterfaces" TEXT)`
);

const recordCommand = (
  `INSERT INTO testdb."networkData" (
    latitude, 
    longitude, 
    "allowsVoIP", 
    speed, 
    uuid, 
    timestamp, 
    "networkType",
    "carrierName", 
    altitude, 
    "macAddress", 
    "publicIP", 
    "ssidLabel", 
    "networkInterfaces"
  ) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)`
);

const params = [
  request.body.latitude,
  request.body.longitude,
  request.body.allowsVoIP,
  request.body.speed,
  request.body.uuid,
  request.body.timestamp,
  request.body.networkType,
  request.body.carrierName,
  request.body.altitude,
  request.body.macAddress,
  request.body.publicIP,
  request.body.ssidLabel,
  request.body.networkInterfaces,
];

const selectData = `SELECT * FROM testdb."networkData"`;

client.connect()
  .then(() => client.execute(createTable))
  .then(() => client.execute(recordCommand, params, { prepare: true }))
  .then(() => client.execute(selectData))
  .then(result => {
    let count = result.rows.length
    if (count > 0)
      console.log(`Total rows : ${count}`)
    else console.log("No rows")
  })
  .catch(error => console.log(error));
