我有一个像这样的发电机数据库查询。我执行该操作以将数据添加到两个不同的表中，这个问题是第一个问题的延续。在dynamodb中使用batchWriteItem

  var createuser = {
        "RequestItems": {
          "users": [
            {
              "PutRequest": {
                Item: {
                  "userid": { "N": "usrid" },
                  "role": { "S": 'candidate' },
                  "password": { "S": vucrypt.encryptpass(pass) }
                }
              }
            }
          ],
          "candidate": [
            {
              "PutRequest": {
                Item: {
                  "fname": {
                    "S": req.body.fname
                  },
                  "lname": {
                    "S": req.body.lname
                  },
                  "location": {
                    "S": req.body.location
                  },
                  "phone": {
                    "S": req.body.phone
                  },
                  "ccode": {
                    "S": req.body.ccode
                  },
                  "grad": {
                    "S": req.body.grad
                  },
                  "pgrad": {
                    "S": req.body.pgrad
                  },
                  "ograd": {
                    "S": req.body.ograd …

我想查询没有主分区键主排序键的 dynamo 数据库表

这些在我的桌子上

Primary partition key   userid (String)
Primary sort key    jobcodeid (String)

该表还包含一个关键的 jobid。

所以我想进行一个如下所示的查询。

  var opts  = {
          'ConsistentRead': true,
          TableName : 'interviews',
          KeyConditionExpression: "jobid = :jobid",
          ExpressionAttributeValues: { ":jobid": {"S":jobid} },
        }

我正在使用这个代码

  dynamodb.query(opts, function(err, data) {
  if(err){
   //somthing
   }else{
   //Somthing
   }
 }

但上面的查询返回这样的错误。

ValidationException: Query condition missed key schema element

我怎样才能执行这个查询？

我的 dynamo db 中有两个表，一个是候选表，另一个是用户表我想在 dynamo db 中使用 batchWriteItem 以便在表中添加数据。

我格式化的查询如下

var user = {
        userid: usrid,
        role: 'candidate',
        password: vucrypt.encryptpass(pass)
      };

      var canduser = {
        fname: req.body.fname,
        lname: req.body.lname,
        location: req.body.location,
        phone: req.body.phone,
        ccode: req.body.ccode,
        grad: req.body.grad,
        pgrad: req.body.pgrad,
        ograd: req.body.ograd,
        experience: exp,
        linkedin: req.body.linkedin,
        terms: tandc
      };
      canduser = vutools.fixcanduser(canduser);
      canduser.userid = usrid;

      var writes = {
        'users': [{put: user}],
        'candidate': [{put: canduser}],
      };

但如果我使用
dynamodb.batchWriteItem(writes, function(err, regdata) { }

它以错误告终。如何编写正确的查询？我得到的错误是这个。

MultipleValidationErrors: There were 3 validation errors:
* MissingRequiredParameter: …

我有以下代码行

<?php
    $userobject = $_SESSION[CATS];
    print_r($userobject);
?>

以这种方式给我一个输出.
