I want to do something as follows in Qlikview.
Need to call the API in the loop till the resp becomes empty array. Also need to append next value in the URL from the response.
TempTable:
Let next = '';
Let apiUrl = https://myapiurl;
do {
resp = Calling my API (apiUrl + next);
push resp.data to TempTable
next = resp.next;
} (while resp.data.length > 0);
Target is I want a consolidate output of the API calls.
Suppose if we can't do it with TempTble, is there any other ways?

I am trying to display document revisions in a paginated list. This will only work when I know the total results count so I can calculate the page count.
For common document queries this is possible with session.Query(...).Statistics(out var stats).
My current solution is the following:
// get paged revisions
List<T> items = await session.Advanced.Revisions.GetForAsync<T>(id, (pageNumber - 1) * pageSize, pageSize);
double totalResults = items.Count;
// get total results in case items count equals page size
if (pageSize <= items.Count || pageNumber > 1)
{
GetRevisionsCommand command = new GetRevisionsCommand(id, 0, 1, true);
session.Advanced.RequestExecutor.Execute(command, session.Advanced.Context);
command.Result.Results.Parent.TryGet("TotalResults", out totalResults);
}
Problem with this approach is that I need an additional request just to get the TotalResults property which indeed has already been returned by the first request. I just don't know how to access it.
You are right the TotalResults is returned from server but not parsed on the client side.
I opened an issue to fix that: https://issues.hibernatingrhinos.com/issue/RavenDB-15552
You can also get the total revisions count for document by using the /databases/{dbName}/revisions/count?id={docId} endpoint, client code for example:
var docId = "company/1";
var dbName = store.Database;
var json = await store.GetRequestExecutor().HttpClient
.GetAsync(store.Urls.First() + $"/databases/{dbName}/revisions/count?id={docId}").Result.Content.ReadAsStringAsync();
using var ctx = JsonOperationContext.ShortTermSingleUse();
using var obj = ctx.ReadForMemory(json, "revision-count");
obj.TryGet("RevisionsCount", out long revisionsCount);
Another way could be getting all the revisions:
var revisions = await session.Advanced.Revisions.GetForAsync<Company>(docId, 0, int.MaxValue);
Then using the revisions.Count as the total count.
I'm trying to send sms using mysms API. I am able to send to single number using following example:
Example: https://api.mysms.com/json/message/send?api_key=xxxxx&msisdn=xxx&password=xxx&recipient=436761234567&message=Hi
How can I send to multiple number using above example?
I came up with this code:
function sendSMS() {
var apikey = "your api_key";
var mno = 40123123456; // msisdn = your number without +sign in from
var pwd = "yourpassword";
// var no = 40123123456; // single number & replace this with a real one
var grp = [40123123456,40123123456,40123123456]; // multiple numbers / let's call it a group & just replace those with your actual testing numbers
var msg = "Hi!%0aThis is a test message!%0aThis is another row.%0a:D"; // Use %0a to insert a new row in your message
for ( var i in grp ) {
var smsurl = "https://api.mysms.com/json/message/send?api_key="+apikey+"&msisdn="+mno+"&password="+pwd+"&recipient="+grp[i]+"&message="+msg+"";
var xhttp = new XMLHttpRequest();
xhttp.open("GET", smsurl, true);
xhttp.send();
console.log(smsurl);
}
}
Now just make the call:
sendSMS();
This code is javascript and I hope will answer your question well. Also it was tested and proven that is working. There is always room for improvements.
Currently working on an API which given an address returns information about is. Some of the rows in our tables are duplicates, however being as there is over 15 million I cant go and find the duplicates. Instead I have opted to use
var query = `SELECT TOP 1 * from my_TABLE where..conditions`;
This ensures that only one row of the duplicates are returned.
The problem is when this is sent back as a JSON it comes as an array with one object.
In the Server.js file
// create Request object
var request = new sql.Request();
// query to the database
request.query(query, function (err, result) {
if (err) {
console.log("Error while querying database :- " + err);
res.send(err);
}
else {
res.send(result)
}
Returns this:
[{
Address:'our info'
}]
is there a way to have it respond with
{
Address:'our info'
}
Because from DB you've get list of object anyway, even there is only 1 item.
It works as you expected when you try to return json with the first element of your array.
I'm using node js 0.10.12 to perform querys to postgreSQL 9.1.
I get the error error invalid input synatx for integer: "{39}" (39 is an example number) when I try to perform an update query
I cannot see what is going wrong. Any advise?
Here is my code (snippets) in the front-end
//this is global
var gid=0;
//set websockets to search - works fine
var sd = new WebSocket("ws://localhost:0000");
sd.onmessage = function (evt)
{
//get data, parse it, because there is more than one vars, pass id to gid
var received_msg = evt.data;
var packet = JSON.parse(received_msg);
var tid = packet['tid'];
gid=tid;
}
//when user clicks button, set websockets to send id and other data, to perform update query
var sa = new WebSocket("ws://localhost:0000");
sa.onopen = function(){
sa.send(JSON.stringify({
command:'typesave',
indi:gid,
name:document.getElementById("typename").value,
}));
sa.onmessage = function (evt) {
alert("Saved");
sa.close;
gid=0;//make gid 0 again, for re-use
}
And the back -end (query)
var query=client.query("UPDATE type SET t_name=$1,t_color=$2 WHERE t_id = $3 ",[name, color, indi])
query.on("row", function (row, result) {
result.addRow(row);
});
query.on("end", function (result) {
connection.send("o");
client.end();
});
Why this not work and the number does not get recognized?
Thanks in advance
As one would expect from the initial problem, your database driver is sending in an integer array of one member into a field for an integer. PostgreSQL rightly rejects the data and return an error. '{39}' in PostgreSQL terms is exactly equivalent to ARRAY[39] using an array constructor and [39] in JSON.
Now, obviously you can just change your query call to pull the first item out of the JSON array. and send that instead of the whole array, but I would be worried about what happens if things change and you get multiple values. You may want to look at separating that logic out for this data structure.
I am trying to get the actual response (the data) from my database using prepared statements:
$stmt=$dbconn->prepare("SELECT user_videos FROM public.account_recover_users WHERE user_mail= :email");
$stmt->execute(array(':videos'=>$json_videos,':email'=>$email));
I know that $stmt->execute(array(':videos'=>$json_videos,':email'=>$email)); will return a boolean, not the actual data. But how to get the data from my database into an array? I will need to later return that data, the script is accessed via a GET request, and I will need to do exit("{'data':$data_from_db}"); so I don't want to fetch each row using foreach($stmt as $row). Just pass it all as it is.
$results = array();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$results[] = $row;
}
