I want to create a view in cb that will show some data based on date-range input.
My question is how can I distinct field from the data?
Here is my map code:
function (doc, meta) {
if(!doc.clipGeneration.fromCache){
var eiid = doc.clipGeneration.batchId;
if (eiid == null){
eiid = "API";
}
if ( !(doc.clipGeneration.externalId.indexOf("API_INTERVAL_TEST")>=0) ) {
emit([doc.clipGeneration.clipStyle, eiid,doc.eventOccurenceTimeStamp[0], doc.eventOccurenceTimeStamp[1], doc.eventOccurenceTimeStamp[2],doc.eventOccurenceTimeStamp[3]], doc.insertRawTimestamp);
emit([doc.clipGeneration.clipStyle, "ALL",doc.eventOccurenceTimeStamp[0], doc.eventOccurenceTimeStamp[1], doc.eventOccurenceTimeStamp[2],doc.eventOccurenceTimeStamp[3]], doc.insertRawTimestamp);
emit([doc.eventOccurenceTimeStamp[0], doc.eventOccurenceTimeStamp[1], doc.eventOccurenceTimeStamp[2],doc.clipGeneration.clipStyle], doc.insertRawTimestamp);
}
}
}
The reduce is _count, and the filters for example are:
startkey: [2015,1,1,null]
endkey: [2015,1,31,"\uffff"]
The output is as expected by the date-range:
{"key":[2015,1,11,"5001188"],"value":1},
{"key":[2015,1,12,"100022"],"value":5},
{"key":[2015,1,12,"155"],"value":11},
{"key":[2015,1,13,"100022"],"value":9},
{"key":[2015,1,13,"155"],"value":6},
{"key":[2015,1,13,"5001159"],"value":1},
{"key":[2015,1,13,"5001190"],"value":3},
{"key":[2015,1,14,"100022"],"value":12},
{"key":[2015,1,14,"5001194"],"value":1},
{"key":[2015,1,15,"100022"],"value":11},
{"key":[2015,1,16,"100022"],"value":10},
{"key":[2015,1,18,"100022"],"value":8},
{"key":[2015,1,18,"5001096"],"value":6},
{"key":[2015,1,18,"5001194"],"value":3}
But as you can see "100022" repeat many times, how can I make somthing like distinct in sql, so it will be shown only once?
Thanks
There is no way to actually make ONLY the ID field distrinct. You can reduce by key, but only the whole key - so [date, id] in your case. You can do this in N1QL, because it has an actual DISTINCT keyword just like SQL, but that's still in developer preview at the moment.

I have few tables which are joined by some conditions.
What I am trying to achieve is Combine 2 SELECT statements in such way where
If there is data in Condition 1 display them OR go to Condition 2 and display data
Condition 1 - I am getting record from table say for exampleA, B, C and D based on some conditions
Condition 2 - I am getting record from table say for example A, B, C and E based on some conditions
What is am trying to achieve is
Display record if it exists in Condition 1
OR
Display record if it exits in Condition 2
Condition 1/ Query 1 - Display data
async getData() {
try {
const data = await this._conn.query(`

NOTE - 1-> I cannot use function or procedure here.
2-> Both the `Conditions` contains `different data`
The problem is, how will the computer choose which option to go to? A computer does not choose, it can't. You have to provide some metric for which to choose. The boolean operator || (or) is for checking if either is true (declarative-sorta), not for imperative. You can 'ask' "is a or b true?" but you can't tell a computer, "do this or that" without any weight to either one which would explain to the computer which to pick and when.
What would be possible is asking,
"If there is data in Condition 1 display them; if not, go to Condition 2 and display data".
If that suits your needs, this is how it could be coded (this is just the framework).
if (data1 != null) {
show data1
}
else {
show data2
}
Or your data could be non-null, but have no contents, in which you could try to get some data from it (say, getChildren() (totally random, I'm just making that up):
if (data1.getChildren() != null) {
show data1
}
else {
show data2
}
I hope you know that this is just pseudocode for the theory of it. show_ is not actual code, it's just the placeholder for whatever you would write. Would this work - checking if it is null and/or checking if its contents are null (i.e., it's empty/without data) and if so then going to the next dataset?
I don't know sql, but I thought that idea of check-null/check-contents-null might help.
My current table looks like this:
Status
Draft
Pending
Complete
I want to sort them based on the value of the cells. Is there a way to do that? I've only been able to sort them using this code:
onChange(status: string){
const sortState: Sort = {active: status, direction: 'desc'};
this.sort.active = sortState.active;
this.sort.direction = sortState.direction;
this.sort.sortChange.emit(sortState);
}
But I want to sort using the values of the status themselves since I'd want to create a button which when click sorts starting from complete or draft or pending.
I'm a little confused by your question, but I think I understand what you're asking.
You're going to want to convert your values into an array and then use the .sort() function. So, assuming you have an array of your cells, we can call that let array = Cell[], you can then access the status of the cells like this:
sortCells(){
let array = Cell[]; // here we're assuming there is already a cell type and a cell.active parameter, like shown in your example.
let possibleValues = ["Draft","Pending","Complete"]; // easier way to compare two values
array.sort((a,b)=>{
let aIndex = possibleValues.indexOf(a.active); // index of gets the location of the element in an array
let bIndex = possibleValues.indexOf(b.active);
if(a > b){
return -1;
} else if(b > a){
return 1;
}else{
return 0; // they are equal
}
})
}
You can read more about sort here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort
I'm trying to create a flash application that will keep track of user generated values. The app should basically allow the user to input the name of the item and it's cost. The total costs should then be added up to show a total value to the user. I can probably figure out how to add the values together, but I'm not really sure how to allow the user to create a list and then allow the user to save it. Can anyone point me towards a tutorial or point me in the right direction?
I am using variables to add user inputed numbers to come up with a total. The first problem is that actionscript 3.0 does not allow variables for texts. I just converted it to 2.0 to fix this. The second problem, is when I test the app and put in my values and click submit, I get NaN in the total values field. Is there a reason why it wouldn't add the values?
Here is the code I used for the submit button:
on (release) {
total = Number(rent) + Number(food) + Number(travel) + Number(entertainment) + Number(bills);
}
Am I missing anything?
Can I give the input text instance names and then give them variables? How are some ways to go about this?
Thanks for the help!
Have an object array, say for example
var stack:Array = new Array();
Then push the item name and it's cost to that array when user inputs, like
stack.push({item:AAA, cost:xx});
So that you can generate the list whenever you want with that array.
You have to see how this works in code. A list in actionscript could be stored inside an array, vector, dictionary or even an Object.
Var myList:Array = [];
myList.push({name: "item 1", cost: 5 });
myList.push({name: "item 2", cost: 7.5 });
If you want to grab the 'product' of "item 1" from the list, you have to create a function for that, lets call it getProductByName
function getProductByName(name:String):Object
{
for each(var product:Object in myList)
{
if (product.name === name) return product;
}
return null; // no match found
}
You can call that function like this:
var product = getProductByName("item 1");
trace(product.cost); // 5
And you can alter the product, so lets make it more expensive
product.cost += 1;
trace(product.cost); // 6
Have fun! If you are using classes, you would create one for the product, with public name and cost, and in that case you'de better use a vector, to ensure working with the right type.
This is what fixed the issue for me in action script 3.0:
myButton.addEventListener(MouseEvent.CLICK, addThem);
function addThem(e:MouseEvent)
{
totalField.text = String ( Number(field1.text) + Number(field2.text) + ....);
}
I also had to name the instances appropriately.
Hmmm, maybe someone can help me out here or point me in the right direction , as i have been banging my head against the wall for a number of days now and dont seem to be gettin anywhere useful.
(and admittedly i'm pretty new with regards to json,objects, google visulization etc)
essentially, i am running 3 different queries on the same page against 3 different fusion tables, which in return are supposed to return an array of 3 different xets of markers.
all is fine, when i run the queries individually and make an array of the markers .
however, running the 3 queries on the same page, i can't seem to find a way to identify the query in the response function.
any hints much appreciated. and i'll be happy to provide more info if needed (tried to get rid of some unneccessary stuff)
this is what i have. thanks
a) calling the function "setFusionData()" with all relevant vars. something like setFusionData("'LatLng','name'", 2729461);
(this is calles 3 times with different variables)
function setFusionData(selColumns,tableId) {
/****
an actual query example is this:
http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
****/
var query = new google.visualization.Query(
'http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq='+ encodeURIComponent("SELECT "+selColumns+" FROM "+tableId+"")
);
query.send(getFusionData); //do something with the response
}
function getFusionData(response) {
/**
here, is the problem as i need to get the table id or reqId or anything that is uniquely passed on from "setFusionData" above
also something like
alert(JSON.stringify(response)) does not return any reqId or table id either
***/
/*return rows/columns and add values to an array of markers***/
var numRows = response.getDataTable().getNumberOfRows();
var numCols = response.getDataTable().getNumberOfColumns();
for (i = 0; i < numRows; i++) {
/* add markers to array etc this works fine***/
}
}
i also tried something like this:
function setFusionData(selColumns,tableId) {
......
query.send(getFusionData({reqId:tableId}));
}
function getFusionData(response) {
alert(response['reqId']);//returns tableId. but how do i get the tableData ?
}
with wich i can get the reqId, but not the table*Data*. So I am only able to get either id or data :(
----edit----------------
after messing around a bit more (see below) it appears that the key/value pairs that get returned when typing the query into the browser directly are different than what gets returned by the call from the script...i.e the following
http ://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
typed directly into the browser bar will return
version:'0.5',reqId:'1234',status:'ok',table etc
however, calling the same from within the script returns something like
{
"rj":"0.5","ef":"ok","pb":[],"qb":[],"h":"{"cols":
[{"id":"col2","label":"LatLng","type":"string"},{"id":"col1","label":"name","type":"string"}],
"rows":
[{"c":[{"v":"47.20572,12.70414"},
{"v":"Hohe Tauern"}]},{"c":[{"v":"47.5530395,12.925611"},{"v":"Berchtesgaden"}]},{"c":[{"v":"47.5585405,14.61887"},{"v":"Gesu00e4use"}]}],
"p":{"totalrows":3}
}"
}
, so no 'reqId' but only some cryptic keys (without one that looks like the reqId either)...... anyone any idea why that would/could be ?
Sometimes you can figure it out by just looking at the JSON response, your sample request returns:
google.visualization.Query.setResponse({
version:'0.5',
reqId:'1234',
status:'ok',
table: {
...
}
})
You already got response.reqId to identify which request is this the response for, now you can use response.table to create a new DataTable instance:
var dt = new google.visualization.DataTable(response.table);
Or, since you have multiple tables, put then in an array indexed with the reqId
tables[response.reqId] = new google.visualization.DataTable(response.table);
You'd do var tables = new Array() before calling setFusionData() for the first time.
I'm attempting to alter the contents of certain parts of a HTML form through usage of the URL. For a text field, I'm aware that this will suffice,
http://<domain>?fieldname=ping&anotherfield=pong
On the form there are multiple select braces (drop down boxes); Is it possible to pick an int or string value through the url for this?
There seems to be little documentation on this (or even people trying to do the same)...
You haven't specified how you want to do this, but I'll assume that you want to use JavaScript:
To get a value from QueryString:
getQueryStringArgument = function(key) {
var hu = window.location.search.substring(1);
var gy = hu.split("&");
for (i = 0; i < gy.length; i++) {
var ft = gy[i].split("=");
if (ft[0] == key)
return ft[1];
}
}
To set the selected value of the select list:
document.getElementById("sel").value = getQueryStringArgument("id");
For a text field, I'm aware that this will suffice
No, it won't (at least, not in a generic way).
For a text field, the default value is specified by the value attribute. There might be a server side script that populates it based on query string data, but there doesn't have to be.
On the form there are multiple select braces (drop down boxes); Is it possible to pick an int or string value through the url for this?
Again, this requires an attribute to be set (selected on <option>), and that could (again) be set by a server side script based on the query string data.
