I want to query a dynamo db table for getting company id but the same table need a hash key so my query is something like this.
var optsq = {
'ConsistentRead': true,
'AttributesToGet': ['companyid'],
TableName : usertable,
Key : {
"userid" : {
"S" : usrname
},
"comapnyid" :{
"S":''
}
}
};
My query will only work if the query has the value of company id as well but i want to get company id how can i achive this. In my node js
dynamodb.getItem(optsq, function(err, compdata) {
if(err){
console.log(err);
}else{
console.log(compdata);
}
Instead of getItem
, you should do a query
, which allows you to specify only the userId
.
var optsq = {
'ConsistentRead': true,
TableName : usertable,
KeyConditionExpression: "userid = :userid",
ExpressionAttributeValues: { ":userid": usrname },
ProjectionExpression: "companyid" }
