Accessing data nested inside a JSON data source in Project Siena

Hi all
I'm trying to work with JSON data sources via REST in Project Siena. I can easily set up the JSON data source and get the data into my data sources list. However, the data is nested, so for example a REST request to search returns JSON data that is unpacked
(correctly) as:
search_query > entries > name
I have tried two different REST-based data sources with the same result. I have tried accessing the data a couple of ways: firstly via a Gallery view and secondly just getting a listing with a DropDown.
For this example, I've tried setting the Data items to search_query!entries (and a bunch of other things) with the idea that I could then refer to ThisItem!name and when that failed trying almost everything I could from the function reference
http://siena.blob.core.windows.net/beta/ProjectSienaBetaFunctionReference.html#_Toc373745469
Should this work? It seems like it's an extremely common structure for JSON returned from a RESTful service (top level containing count, pagination, other data and then a set of result details beneath).
Any ideas appreciated. For completeness, the two data sources I've tried are the Box.com Content API (Search and Folders) and the ZenDesk API (Groups).
Cheers.

What you get back from the call is essentially a table with a single row--the "entries" column within that row have multiple rows that contain the name data. Try binding First(search_query)!entries to extract the name records.

Using s SQL server as a data source for Project Siena (An AX SQL database more specificaly)?

I cant seem to find this information on the internet yet so I figured I would ask my question here.
I would like to pull data from a Dynamics AX sql database to use in a project siena app. I have heard that this is something that is planned for a future release of Siena but is there any way this can be done currently?
Thank you

Hi Philip,
It's not supported in the current version. The following thread from Vijay outlines some of the features targeted for the next release:
http://social.technet.microsoft.com/Forums/en-US/405aed19-21b8-4a36-bf45-b1d962567c3b/some-functionality-in-the-next-siena-refresh?forum=projectsiena. As you can see, it will include read/write over web services. So, if your data is exposed using services,
you should be able to meet your requirements.

The data type of "output column "Cookies" (7371)" does not match the data type "System.Int32" of the source column "Cookies"

I have the following data flow:
ADO Source
Input Column: Cookies ID: 7371      Datatype: DT_NUMERIC
Output Column: Cookies     ID: 7391      Datatype: DT_NUMERIC
DATA CONVERSION TASK
Input Column: Cookies       ID: 1311     Datatype: DT_NUMERIC
Output Column: Copy of Cookies   ID: 1444    Datatype: DT_I4
SQL Server Destination
Input Column: Copy of Cookies    ID: 8733    Datatype: DT_I4
Output Column: Cookies       ID: 8323     Datatype: DT_I4
This looks fine to me. Why am I getting the error?
This is SQL Server 2008 and I am working at this point only in BIDS, so it is not a question of dev vs prod server or anything. One environment, running in BIDS. Other similar data flows seems to be working ok. It seems the error is referring to a datatype
mismatch in the source--but how can that be?
Thanks!

Actually, I am wrong in that Visakh. I think you are correct.
There are two versions of all tables, one with 15 minute rollups and one with daily rollups. Otherwise the tables are the same--same exact fields. I use a loop with a data flow inside to get data from one version of the rollup and then the other.
The problem is, for some of the fields with larger values the datatype is NUMERIC instead of INTEGER. (This is Cache database). SO:
dailyCookies:   Field: CountOne   Datatype: NUMERIC
15minCookies:   Field: CountOne   Datatype: INTEGER
A variable dynamically creates the query so it appends "daily" or "15min" to the beginning of the tables. So on the first loop it does the 15min tables and on the second the daily tables. When I created this particular table I have to plug a default query
in so I used the daily. It picked up the datatype as NUMERIC so when I run the package it loops through 15min first and sees the datatype is INTEGER.
How to deal with this? I suppose I could convert the datatype in the source query, but that would be a hassle to do that for some fields and not others. This tables has hundreds of fields, BTW. Can one source object deal with a change of datatypes? SSIS
is so picky on datatypes compared to other tools....

Populating JSON Data to Combobox - Need Help!

Hello,
I am trying to use a dynamicly created JSON comming from a webservice to populate comboboxes. I am really new to Flex and ActionScript 3.0.
The problem what i have here is that my combobox stays empty. I am trying to fill it with all values from "key" (representing the manufacturers)
Here´s my Code so far:
[CODE]<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*" layout="absolute"

            public var myURL:String = "http://dev.ws.topdata.de/data/tdifdata.php?";
            public var params:Object = {Lookup: "DeviceManufacturerId"};
            private function onJSONLoad(event:ResultEvent):void
                //get the raw JSON data and cast to String
                var rawData:String = String(event.result);
                //decode the data to ActionScript using the JSON API
                //in this case, the JSON data is a serialize Array of Objects.
                var arr:Array = (JSON.decode(rawData) as Array);
                //create a new ArrayCollection passing the de-serialized Array
                //ArrayCollections work better as DataProviders, as they can
                //be watched for changes.
                var dp:ArrayCollection = new ArrayCollection(arr);
                //pass the ArrayCollection to the Combobox as its dataProvider.
                dropdown.dataProvider = dp;
                trace(rawData);
        ]]>
    </mx:Script>
    <mx:HTTPService id="service" method="GET" resultFormat="text" url="{myURL}" result="onJSONLoad(event)">
    </mx:HTTPService>
    <s:ComboBox x="26" y="33" labelField="key" id="dropdown"/>
</mx:Application>[/CODE]
trace(rawData); returns something like
[CODE]"1607":
            "key": "Xitan",
            "value": "2283",
            "isPremium": "0"

            "value": "2284",
            "isPremium": "0"
    "1609": [/CODE]
Now i´ve tried to bind this dataProvider for my first combobox listing all items with the value from "key" but my combobox stays blank/empty....

I tried the following now and it says "can´t convert obect@... to Array" maybe there is something wrong with the JSON outout from the webservice? But the JSON from the webservice validates, however if i test it with a small own JSON file locally it works...

"Syntax error or access violation" on Data Flow Task OLE DB Data Source

I am implementing expression parameter for a SQL Server connection string (like this: http://danajaatcse.wordpress.com/2010/05/20/using-an-xml-configuration-file-and-expressions-in-an-ssis-package/) and it works fine except when it reaches data flow
task - OLE DB Source task. In this task, I execute a stored procedure like this:
exec SelectFromTableA ?,?,?
The error message is this:
0xC0202009 at Data Flow Task, OLE DB Source [2]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description: "Syntax error or access violation".
Error: 0xC004706B at Data Flow Task, SSIS.Pipeline: "OLE DB Source" failed validation and returned validation status "VS_ISBROKEN"
When I change the SQL command above with reading from table directly it works fine. I should also add that before changing connection string of the SQL data source to use expression, the SSIS package was working fine and I know that the connection string
is fine because other tasks in the package works fine!
Any idea why?

Hi AL.M,
As per my understanding, I think this problem is due to the mismatching between the source and the destination tables. We can reconfigured every of components of the package to check the table schemas and configuration settings, close the BIDS/SSDT and then
open and try to see if there are errors.
Besides, to trouble shoot this issue, we can use the variable window to see the variable's value. For more details, please refer to the following blog:
http://consultingblogs.emc.com/jamiethomson/archive/2005/12/05/2462.aspx

Access denied to a READ-ONLY data source

Post Author: covey9257
CA Forum: Data Connectivity and SQL
I'm using Crystal 10 sevice pack 6. My report is using an ODBC connection to a PSql 9.5 stored procedure. The stored procedure creates a temp table and inserts records from 3 different ticket tables. It has one parameter in it that selects which location to load the table with. My report works fine as long as I don't try to put any of the fields from the temp table on the report. If I do, then I get the following error.
Failed to open a rowset. Details: 42000:[Pervasive][ODBC Client Interface][LNA][Pervasive][ODBC Engine Interface][Data Record Manager][SPEng][Pervasive][ODBC Engine Interface]Access denied to a READ-ONLY data source.
I found that this was an issue in Crystal 9.0, but nothing with cr 10.
Does anyone know of a work around or fix for this scenario??
Thanks - Cathy

Thanks for the quick reply Don.
If you have the option that Pervasive uses to not use the exclusive lock on the DB try adding it to the SQLExpression function in CR.
I am not sure how to accomplish this. I've done some quick searching but cannot come up with SQL that indicates locking unless I am using some kind of language like VB or C#.
Here is my Command Object statement
INSERT INTO RASAPSign
(sVendNo, sChqNo, dtDateSigned)
VALUES
('{?VendNum}', '{?ChqNum}', CURDATE());
SELECT sVendNo, sChqNo, dtDateSigned
FROM RASAPSign
WHERE sVendNo = '{?VendNum}' and sChqNo = '{?ChqNum}'
Can you give me an idea of what to change? Or at least what terminology to search for?
I tried this option with BEGIN and END
BEGIN
INSERT INTO RASAPSign
(sVendNo, sChqNo, dtDateSigned)
VALUES
('{?VendNum}', '{?ChqNum}', CURDATE());
END
SELECT sVendNo, sChqNo, dtDateSigned
FROM RASAPSign
WHERE sVendNo = '{?VendNum}' and sChqNo = '{?ChqNum}'
But I get a syntax error.
Thanks, rasinc

Accessing JSON Data for Expired or Disabled Webapps

I would like the ability to access webapp items that are either expired or disabled from the outputted JSON data. The reason I would like the ability to check how many web app items a user has submitted and have expired (the webapp items have a time limit of 3 weeks then are disabled) is then I can write liquid code letting the user know they have reached their limit.
In the meantime, is there a workaround for implementing something like this? Thanks.

Save the data in the file as json data

Hello,
I need to read data from list / Pictures gallery / Documents and save the returned data in the file as json data .
How Can I Implement that .
ASk

Try below:
http://msdn.microsoft.com/en-us/library/office/jj164022%28v=office.15%29.aspx
The code in the following example shows you how to request a JSON representation of all of the lists in a site by using C#. It assumes that you have an OAuth access token that you are storing in the
accessToken variable.
C#
HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create(sharepointUrl.ToString() + "/_api/web/lists");
endpointRequest.Method = "GET";
endpointRequest.Accept = "application/json;odata=verbose";
endpointRequest.Headers.Add("Authorization", "Bearer " + accessToken);
HttpWebResponse endpointResponse = (HttpWebResponse)endpointRequest.GetResponse();
Getting properties that aren't returned with the resource
Many property values are returned when you retrieve a resource, but for some properties, you have to send a
GET request directly to the property endpoint. This is typical of properties that represent SharePoint entities.
The following example shows how to get a property by appending the property name to the resource endpoint. The example gets the value of the
Author property from a File resource.
http://<site url>/_api/web/getfilebyserverrelativeurl('/<folder name>/<file name>')/author
To get the results in JSON format, include an Accept header set to
"application/json;odata=verbose".

Create report based on JSON data

Dear All,
I'm on Oracle APEX 4.1 and Oracle 11g. I'm receiving JSON data in my application and would like to print report based on JSON data without storing it in any table.
Can you please suggest best way to achieve it?
Regards,
Chintan

Hi,
in 4.1 you can for example use the open source PL/JSON library (http://sourceforge.net/projects/pljson/) to parse JSON.
In APEX 5.0, we currently plan to add a JSON API package that e.g. can be used to convert JSON to XML. Here is an example:
SQL> select col1, col2
2 from xmltable (
3      '/json/row'
4      passing apex_json.parse('[{"col1": 1, "col2": "hello"},{"col1": 2, "col2": "world"}]')
5      columns
6          col1 number path '/row/col1',
7          col2 varchar2(5) path '/row/col2' );
                COL1 COL2
                   1 hello
                   2 world
At the last OOW, it was also announced that the RDBMS will provide native support. That should be the preferred option in the future.

Parsing Json data to Array

i have json string which i want to parse in string and add in Array,
also i want to access this value as per field name to display in TextBox.
i have parse the json data in string format but i want to add it in array as per their field name,so that i can access it in textfields.
[{"userid":1,"uname":"andruw","address":"west","city":"london","email":"[email protected]"},
{"userid":2,"uname":"pamela","address":"east","city":"london","email":"[email protected]"},
{"userid":3,"uname":"penny","address":"south","city":"paris","email":"[email protected]"},
{"userid":4,"uname":"jhon","address":"north","city":"zurich","email":"[email protected]"}]

Why do you wnat it string in hte first place, now you need to split it to get the info. The honest thing to do is to create a custom class to hold this info and populate the array with objects created from JSON. That way you can easily map data to UI controls.
class Person
    userId:int;
    uname:String;
    address:String;
    city:String;
    email:String;
My 2 cents,

How to retrieve data from inside the folders in SharePoint SSRS

Hi ,
How to get the data from inside the folders and subfolders.
How can I do that.

Vinod

Hi Vinodaggarwal87,
According to your description, you want to retrieve data from sharepoint list in a sub folder. Right?
In this scenario, we should select the XML data source type and in the connection string provide the
List.asmx service URL when creating data source. Then we need to use the List web Service and specify "recursive" for ViewAttribute in Lists.asmx. For detail steps, please refer to the links below:
Generate SSRS report on SharePoint List with folders using List Service.
SSRS: how to specify ViewAttributes when creating a report against a SharePoint's list
If you want to set the ViewAttribute on CAML query level. You need add the view tag outside of query tag:
<View Scope="RecursiveAll">
    <Query>
        <Where>...</Where>
    </Query>
</View>
Reference:

If you have any question, please feel free to ask.

AdvancedDataGrid populated by JSON data

Hi, I'm currently use an AdvancedDataGrid to show a HierarchicalData from and XML file.
It works but now I have to use a JSON data and for a DataGrid with a simple Data Provider I have no problem.
Is it possible to use a JSON source for a HierchicalData?
Thanks,
David

We don't have support for that type of thing built into Muse.
If you find a solution using HTML/JS etc., you maybe be able to insert it into a Muse site using Object -> Insert HTML and accomplish what you are after.

Did you look at the example in the jqGrid Demos page? The answer is there.
Open http://trirand.com/blog/jqgrid/jqgrid.html
Open Chrome Developer Tools
See what is the URL when you click the next page button on the grid?
http://trirand.com/blog/jqgrid/server.php?q=1&_search=false&nd=1374957231342&rows=10&page= 2&sidx=id&sord=desc
If you click the previous page:
http://trirand.com/blog/jqgrid/server.php?q=1&_search=false&nd=1374957248411&rows=10&page= 1&sidx=id&sord=desc
As you can see the page value in the query string change from 2 to 1.
Then, see the PHP code. The page variable is use to retrieve data.
That means if you give a number of rows, the grid does not calculate page number automatically. You should do the calculation from the CFC.

CFAJAXPROXY - getting JSON data ?

I want to pass JSON formatted data to JavaScript components
(I want to use Yahoo Interface framework) - CFC methods accessed
via CFAJAXPROXY tag automatically return results already converted
to JavaScript so my question is how do I either suppress the
JavaScript conversion or how do I reference the JSON data returned
by the method (which I can see in the debugger).

You should be able to use the SP.WebProxy to make the remote REST call. You will have to list the endpoint in your AppManifest under RemoteEndPoints. You can read more in the link below. The REST call method using jQuery is in the second option.
