Question

当我尝试使用下面提到的代码

从redshift中获取数据时，我遇到了以下错误

var jdbc = new ( require('jdbc') );
var config = {
  libpath: 'C:/Users/ABCD/Desktop/jar/RedshiftJDBC41-1.1.6.1006.jar',
  //libs: [__dirname + 'path/to/other/jars.jar'],
  drivername: 'com.amazon.redshift.jdbc41.Driver',
  url: 'jdbc:redshift://examplecluster.abc123xyz789.us-west-2.redshift.amazonaws.com:5439/dev',
  user: 'xxxx',
  password: 'xxxxx'
};

jdbc.initialize(config, function(err, res) {
    if (err) {
    console.log(err);
  }
});

var genericQueryHandler = function(err, results) { 
  if (err) {
      console.log(err);
  } else if (results) {
      console.log(results);
}

jdbc.close(function(err) {
  if(err) {
    console.log(err);
  } else {
    console.log("Connection closed successfully!");
  }
});
};

jdbc.open(function(err, conn) {
if (conn) {
     // SELECT statements are called with executeQuery 
     jdbc.executeQuery("select * from information_schema.tables", genericQueryHandler);
}
});

错误：

C:\Users\ABCD> node redshift.js
C:\Users\ABCD\node_modules\jdbc\lib\jdbc.js:62> 
if(this._props.getPropertySync('user') === undefined){> 
  ^ TypeError: undefined is not a function

有什么可以让我知道上面提到的节点jdbc用于redshift是否有问题？

从节点jdbc进行Redshift数据访问
